200-623: The Union Army Balloon Corps was a branch of the Union Army during the American Civil War , established by presidential appointee Thaddeus S. C. Lowe . It was organized as a civilian operation, which employed a group of prominent American aeronauts and seven specially built, gas-filled balloons to perform aerial reconnaissance on the Confederate States Army . Lowe was one of a few veteran balloonists who

400-603: A brevet brigadier general when the war ended. Francis B. Spinola recruited four regiments in New York, was soon appointed Brigadier General by President Abraham Lincoln and given command of the Spinola Brigade . Later he commanded another unit, the famed Excelsior Brigade . The Garibaldi Guard recruited volunteers for the Union army from Italy and other European countries to form the 39th New York Infantry . At

600-567: A diplomatic cable , is a confidential communication between a diplomatic mission and the foreign ministry of its parent country. These continue to be called telegrams or cables regardless of the method used for transmission. Passing messages by signalling over distance is an ancient practice. One of the oldest examples is the signal towers of the Great Wall of China . In 400 BC , signals could be sent by beacon fires or drum beats . By 200 BC complex flag signalling had developed, and by

800-575: A Washington warehouse. Eventually the Excelsior was sent to Camp Lowe, a high altitude observation point, as a back-up balloon to the Intrepid during harsh winter weather, but the United States was never put into service. LaMountain made reference to these two balloons in his diatribes against Lowe as "being hoarded" by Lowe so he could buy them unused at the end of the war. Initially, Lowe

1000-449: A chief quartermaster, a chief commissary of subsistence, an assistant inspector general, an ordnance officer (all with the rank of colonel ) and a medical director. The actual number of personnel assigned to an army's headquarters could be quite large: at Gettysburg the headquarters of General Meade (excluding engineers, the artillery reserve and the headquarters of each corps) was no less than 3,486 strong. The military organization of

1200-416: A civilian he wore no uniform nor insignias. With each descent came the threat of being fired on, and to make each descent Lowe needed to release gas. In one instance Lowe was forced to land behind enemy lines and await being rescued overnight. After this incident he remained tethered to the ground by which he could be reeled in at a moment's notice. Besides, his use of the telegraph from the balloon car required

1400-622: A civilian operation the Balloon Corps would have never been expected to drop ordnance. Union Army American Indian Wars American Civil War Appomattox Court House During the American Civil War , the United States Army , the land force that fought to preserve the collective Union of the states , was often referred to as the Union army , the federal army , or the northern army . It proved essential to

1600-453: A code by itself. The term heliostat is sometimes used as a synonym for heliograph because of this origin. The Colomb shutter ( Bolton and Colomb , 1862) was originally invented to enable the transmission of morse code by signal lamp between Royal Navy ships at sea. The heliograph was heavily used by Nelson A. Miles in Arizona and New Mexico after he took over command (1886) of

1800-647: A demonstration with his own balloon, the Enterprise , from the lawn of the armory directly across the street from the White House . From a height of 500 feet (150 m) he telegraphed a message to the President describing his view of the Washington, D.C. , countryside. Eventually he was chosen over other candidates to be chief aeronaut of the newly formed Union Army Balloon Corps. The Balloon Corps with

2000-410: A distance and cablegram means something written via a cable, whereas telegraph implies the process of writing at a distance. Later, a Telex was a message sent by a Telex network, a switched network of teleprinters similar to a telephone network. A wirephoto or wire picture was a newspaper picture that was sent from a remote location by a facsimile telegraph . A diplomatic telegram, also known as

2200-470: A distance of a quarter of a mile. In the 1890s inventor Nikola Tesla worked on an air and ground conduction wireless electric power transmission system , similar to Loomis', which he planned to include wireless telegraphy. Tesla's experiments had led him to incorrectly conclude that he could use the entire globe of the Earth to conduct electrical energy and his 1901 large scale application of his ideas,

2400-577: A few ascents in the balloon and was able to signal his observations of the battlefield to men on the ground using a wigwag system that he had devised. The coal gas used in the balloon was only able to keep the balloon aloft for about three to four hours at a time. The patchwork silk was given to Lowe, who had no use for it but to cut it up and distribute it to Congress as souvenirs. The inflated spheres appeared as multi-colored orbs over Richmond and were piloted by Captain Landon Cheeves. The balloon

2600-558: A few days later, and by 18 May, he had set up a balloon camp at Gaines' Farm across the Chickahominy River north of Richmond, and another at Mechanicsville . From these vantage points, Lowe, his assistant James Allen, and his father Clovis were able to overlook the Battle of Seven Pines . A small contingent from Gen. Samuel P. Heintzelman 's corps crossed the river toward Richmond and was slowly being surrounded by elements of

2800-473: A few days, sometimes taking all day to send a message despite the use of the highly sensitive mirror galvanometer developed by William Thomson (the future Lord Kelvin ) before being destroyed by applying too high a voltage. Its failure and slow speed of transmission prompted Thomson and Oliver Heaviside to find better mathematical descriptions of long transmission lines . The company finally succeeded in 1866 with an improved cable laid by SS Great Eastern ,

3000-474: A ground crew who could reel him in. Wise and LaMountain had been longtime detractors of Prof. Lowe, but LaMountain maintained a vitriolic campaign against Lowe to discredit him and usurp his position as Chief Aeronaut. He used the arena of public opinion to revile Lowe. But as Gen. Butler was replaced at Fort Monroe, LaMountain was assigned to the Balloon Corps under Lowe's command. LaMountain continued his public derogation of Lowe as well as creating ill-will among

3200-645: A hand-selected team of expert aeronauts served at Yorktown , Seven Pines , Antietam , Fredericksburg , and other major battles of the Potomac River and the Virginia Peninsula . The Balloon Corps served the Union Army from October 1861 until the summer of 1863, when it was disbanded following the resignation of Lowe. The use of balloons as an air-war mechanism was first recorded in France by

3400-505: A hundred Black men were eventually made officers (not counting those passing as white), none were promoted to a rank higher than major. If captured by Confederate forces, Black soldiers risked being made slaves or summarily executed . Women took on many significant roles in the Union army and were important to its ultimate success on the battlefield. The most direct way they could help was to enlist and fight as soldiers, although women were officially barred from doing so. Nevertheless, it

3600-514: A letter of outrage and threatened to resign his position. No one came to his support, and Comstock remained unyielding. On 8 April 1863, Lowe left the military service and returned to the private sector. Direction of the Balloon Corps defaulted to the Allen brothers, but they were not as competent as Lowe. By 1 August 1863, the Corps was no longer used. Manned air-war mechanisms became important again to

3800-641: A marvel of engineering. They were designed to be loaded into box crates that could easily fit on a standard buckboard . The generators took more time to build than the balloons and were not as readily available as the first balloon. By 1 October 1861, the first balloon, the Union , was ready for action. Though it lacked a portable gas generator, it was called into immediate service. It was gassed up in Washington and towed overnight to Lewinsville via Chain Bridge . The fully covered and trellised bridge required that

4000-555: A message was relayed 640 km (400 mi) in four hours. Miles' enemies used smoke signals and flashes of sunlight from metal, but lacked a sophisticated telegraph code. The heliograph was ideal for use in the American Southwest due to its clear air and mountainous terrain on which stations could be located. It was found necessary to lengthen the morse dash (which is much shorter in American Morse code than in

4200-493: A modification of surveying equipment ( Gauss , 1821). Various uses of mirrors were made for communication in the following years, mostly for military purposes, but the first device to become widely used was a heliograph with a moveable mirror ( Mance , 1869). The system was used by the French during the 1870–71 siege of Paris , with night-time signalling using kerosene lamps as the source of light. An improved version (Begbie, 1870)

4400-606: A natural rubber from the Palaquium gutta tree, after William Montgomerie sent samples to London from Singapore in 1843. The new material was tested by Michael Faraday and in 1845 Wheatstone suggested that it should be used on the cable planned between Dover and Calais by John Watkins Brett . The idea was proved viable when the South Eastern Railway company successfully tested a three-kilometre (two-mile) gutta-percha insulated cable with telegraph messages to

4600-478: A new balloon. He also proposed that Lowe pilot the new balloon. Prof. Lowe was vehemently opposed to flying one of Wise's old-style balloons. The engineers waited the whole month of July for Wise to arrive on scene. By 19 July 1861, McDowell started calling for a balloon to be brought to the front at First Bull Run ( Centreville ). As Wise was not to be found, Whipple sent Lowe out to inflate his balloon and prepare to set out for Falls Church . Mary Hoehling tells of

4800-416: A position. However, there were no proposed details to the establishment of such a unit, or whether it would even be a military or civilian operation. Nor was there any set method to the process of selecting a Chief Aeronaut, rather it became a free-for-all in attempts to attract the attention of any officials in either the government or the military. In actuality the use of balloons was left to the discretion of

5000-461: A role. Thus for example, comparing two infantry regiments at their full authorized strength one might have twice as many soldiers as the other. Furthermore, even when units were of equivalent size, their actual effectiveness depended greatly on training, leadership, equipment and other factors. During the course of the Civil War, the vast majority of soldiers fighting to preserve the Union were in

5200-551: A scientist. His attempts at free flight in preparation for a transatlantic crossing were less than successful, and he did not receive the same type of financial support from the patrons of the sciences, nor did he carry the overall scientific credibility of Lowe. Wise was, however, taken seriously enough by the Topographical Engineers to be asked to build a balloon. Mary Hoehling indicated that Captain Whipple of

5400-614: A ship off the coast of Folkestone . The cable to France was laid in 1850 but was almost immediately severed by a French fishing vessel. It was relaid the next year and connections to Ireland and the Low Countries soon followed. Getting a cable across the Atlantic Ocean proved much more difficult. The Atlantic Telegraph Company , formed in London in 1856, had several failed attempts. A cable laid in 1858 worked poorly for

5600-440: A single-needle telegraph was adapted to indicate just two messages: "Line Clear" and "Line Blocked". The signaller would adjust his line-side signals accordingly. As first implemented in 1844 each station had as many needles as there were stations on the line, giving a complete picture of the traffic. As lines expanded, a sequence of pairs of single-needle instruments were adopted, one pair for each block in each direction. Wigwag

5800-663: A substantial distance was by Ronalds in 1816 using an electrostatic generator . Ronalds offered his invention to the British Admiralty , but it was rejected as unnecessary, the existing optical telegraph connecting the Admiralty in London to their main fleet base in Portsmouth being deemed adequate for their purposes. As late as 1844, after the electrical telegraph had come into use, the Admiralty's optical telegraph

6000-672: A superb scene. I have pleasure in sending you this first dispatch ever telegraphed from an aerial station and in acknowledging indebtedness to your encouragement for the opportunity of demonstrating the availability of the science of aeronautics in the service of the country. T.S.C. Lowe. Lowe's first assignment was with the Topographical Engineers, where his balloon was used for aerial observations and map making. Eventually he worked with Major General Irvin McDowell , who rode along with Lowe making preliminary observations over

6200-418: A system for mass distributing information on current price of publicly listed companies. In a punched-tape system, the message is first typed onto punched tape using the code of the telegraph system—Morse code for instance. It is then, either immediately or at some later time, run through a transmission machine which sends the message to the telegraph network. Multiple messages can be sequentially recorded on

6400-503: A system of communication that would allow the central government to receive intelligence and to transmit orders in the shortest possible time. On 2 March 1791, at 11 am, they sent the message "si vous réussissez, vous serez bientôt couverts de gloire" (If you succeed, you will soon bask in glory) between Brulon and Parce, a distance of 16 kilometres (10 mi). The first means used a combination of black and white panels, clocks, telescopes, and codebooks to send their message. In 1792, Claude

6600-534: A telefax machine. In 1855, an Italian priest, Giovanni Caselli , also created an electric telegraph that could transmit images. Caselli called his invention " Pantelegraph ". Pantelegraph was successfully tested and approved for a telegraph line between Paris and Lyon . In 1881, English inventor Shelford Bidwell constructed the scanning phototelegraph that was the first telefax machine to scan any two-dimensional original, not requiring manual plotting or drawing. Around 1900, German physicist Arthur Korn invented

6800-466: A telegraph between St Petersburg and Kronstadt , but it was never completed. The first operative electric telegraph ( Gauss and Weber , 1833) connected Göttingen Observatory to the Institute of Physics about 1 km away during experimental investigations of the geomagnetic field. The first commercial telegraph was by Cooke and Wheatstone following their English patent of 10 June 1837. It

7000-415: A wire be run along the tether. LaMountain, from his position at Fort Monroe, had the luxury of flying free. When he was enjoined with the Balloon Corps, he began insisting that his reconnaissance flights be made free. Lowe strictly instructed his men against free flight as a matter of policy and procedure. Eventually the two men agreed to a showdown in which LaMountain made one of his free flights. The flight

7200-465: Is a form of flag signalling using a single flag. Unlike most forms of flag signalling, which are used over relatively short distances, wigwag is designed to maximise the distance covered—up to 32 km (20 mi) in some cases. Wigwag achieved this by using a large flag—a single flag can be held with both hands unlike flag semaphore which has a flag in each hand—and using motions rather than positions as its symbols since motions are more easily seen. It

7400-519: Is a telegraph consisting of a line of stations in towers or natural high points which signal to each other by means of shutters or paddles. Signalling by means of indicator pointers was called semaphore . Early proposals for an optical telegraph system were made to the Royal Society by Robert Hooke in 1684 and were first implemented on an experimental level by Sir Richard Lovell Edgeworth in 1767. The first successful optical telegraph network

7600-458: Is a telegraph machine that can send messages from a typewriter-like keyboard and print incoming messages in readable text with no need for the operators to be trained in the telegraph code used on the line. It developed from various earlier printing telegraphs and resulted in improved transmission speeds. The Morse telegraph (1837) was originally conceived as a system marking indentations on paper tape. A chemical telegraph making blue marks improved

7800-571: Is a telegraph system using reflected sunlight for signalling. It was mainly used in areas where the electrical telegraph had not been established and generally used the same code. The most extensive heliograph network established was in Arizona and New Mexico during the Apache Wars . The heliograph was standard military equipment as late as World War II . Wireless telegraphy developed in the early 20th century became important for maritime use, and

8000-575: Is believed hundreds of women disguised themselves as men in order to enlist. While many were discovered and forced to quit, others were only found out after they were killed in combat, and a number managed to serve throughout the entire war with their true identity successfully concealed. One of the more traditional roles played by women in the Union army was that of camp followers . Thousands of white and Black women accompanied Union armies in an unofficial capacity to provide their services as cooks , laundresses , nurses and/or prostitutes . Many were

8200-447: Is that it permits duplex communication. The Wheatstone tape reader was capable of a speed of 400 words per minute. A worldwide communication network meant that telegraph cables would have to be laid across oceans. On land cables could be run uninsulated suspended from poles. Underwater, a good insulator that was both flexible and capable of resisting the ingress of seawater was required. A solution presented itself with gutta-percha ,

8400-616: Is the long-distance transmission of messages where the sender uses symbolic codes, known to the recipient, rather than a physical exchange of an object bearing the message. Thus flag semaphore is a method of telegraphy, whereas pigeon post is not. Ancient signalling systems, although sometimes quite extensive and sophisticated as in China, were generally not capable of transmitting arbitrary text messages. Possible messages were fixed and predetermined, so such systems are thus not true telegraphs. The earliest true telegraph put into widespread use

8600-645: The Bildtelegraph widespread in continental Europe especially since a widely noticed transmission of a wanted-person photograph from Paris to London in 1908 used until the wider distribution of the radiofax. Its main competitors were the Bélinographe by Édouard Belin first, then since the 1930s, the Hellschreiber , invented in 1929 by German inventor Rudolf Hell , a pioneer in mechanical image scanning and transmission. The late 1880s through to

9000-662: The American Civil War began in April 1861, the U.S. Army included ten regiments of infantry , four of artillery , two of cavalry , two of dragoons , and one of mounted rifles . The regiments were scattered widely. Of the 197 companies in the U.S. Army, 179 occupied 79 isolated posts in the West , and the remaining 18 manned garrisons east of the Mississippi River , mostly along the Canada–United States border and on

9200-484: The Atlantic. John LaMountain , born in 1830, had accrued quite a reputation in the field of aeronautics. He had joined company with Wise at one time to help with the plans for a transatlantic flight. Their attempt failed miserably, wrecked their balloon, the Atlantic , and ended their partnership. LaMountain took possession of the balloon. LaMountain's contributions and successes were minimal. However, he did attract

9400-527: The Department of War . These included, at the onset of the war, the adjutant general , inspector general , paymaster-general , judge advocate general , chief of engineers , chief of topographical engineers , quartermaster general , commissary general of subsistence, chief of ordnance , and surgeon general . After the war started, the position of Provost Marshal General was also created. Originally established on September 24, 1862, as an office in

9600-660: The English Channel (1899), from shore to ship (1899) and finally across the Atlantic (1901). A study of these demonstrations of radio, with scientists trying to work out how a phenomenon predicted to have a short range could transmit "over the horizon", led to the discovery of a radio reflecting layer in the Earth's atmosphere in 1902, later called the ionosphere . Radiotelegraphy proved effective for rescue work in sea disasters by enabling effective communication between ships and from ship to shore. In 1904, Marconi began

9800-508: The First Macedonian War . Nothing else that could be described as a true telegraph existed until the 17th century. Possibly the first alphabetic telegraph code in the modern era is due to Franz Kessler who published his work in 1616. Kessler used a lamp placed inside a barrel with a moveable shutter operated by the signaller. The signals were observed at a distance with the newly invented telescope. An optical telegraph

10000-613: The French Aerostatic Corps at the Battle of Fleurus in 1794. U. S. President Abraham Lincoln became interested in an air-war mechanism for reconnaissance purposes. This created a notion at the War Department and at the Treasury that some sort of balloon aviation unit need be established and headed by a "Chief Aeronaut". Several top American balloonists traveled to Washington in hopes of obtaining just such

10200-589: The Han dynasty (200 BC – 220 AD) signallers had a choice of lights, flags, or gunshots to send signals. By the Tang dynasty (618–907) a message could be sent 1,100 kilometres (700 mi) in 24 hours. The Ming dynasty (1368–1644) added artillery to the possible signals. While the signalling was complex (for instance, different-coloured flags could be used to indicate enemy strength), only predetermined messages could be sent. The Chinese signalling system extended well beyond

10400-532: The London and Birmingham Railway line's chief engineer. The messages were for the operation of the rope-haulage system for pulling trains up the 1 in 77 bank. The world's first permanent railway telegraph was completed in July 1839 between London Paddington and West Drayton on the Great Western Railway with an electric telegraph using a four-needle system. The concept of a signalling "block" system

10600-838: The Official Records of the Union and Confederate Armies , there were over 200 Italians who served as officers in the U.S. army. By 1860, the African American or Black population of the United States consisted of four million enslaved and half a million free Blacks . When the Civil War began, many freedmen in the North attempted to enlist in federal service but were barred from doing so. Popularly-held prejudices doubted whether Black people could be effective soldiers, and President Lincoln believed allowing their enlistment would anger Northern whites and alienate not just

10800-540: The Smithsonian Institution , who became his greatest benefactor. On Henry's and others' recommendations, Lowe was contacted by Secretary of the Treasury Salmon P. Chase , who invited him to Washington for an audience with Secretary of War Simon Cameron and the President. On 11 June 1861, Lowe was received by Lincoln and immediately offered to give the President a live demonstration with

11000-826: The Southwest was still part of Mexico . Some Confederate propaganda condemned foreign-born soldiers in the Union army, likening them to the German Hessian troops who fought alongside the British Army during the American Revolutionary War . A relatively smaller number of Native Americans , including members of Cherokee , Chickasaw , Choctaw and Muscogee peoples, fought for the Confederacy. The great majority of Italian Americans , for both demographic and ideological reasons, served in

11200-509: The U.S. East Coast . There were only 16,367 servicemen in the U.S. Army, including 1,108 commissioned officers. Approximately 20% of these officers, most of them Southerners , resigned, choosing to tie their lives and fortunes to the Confederate army . Almost 200 United States Military Academy graduates who previously left the U.S. Army, including Ulysses S. Grant , William Tecumseh Sherman , and Braxton Bragg , returned to service at

11400-526: The Washington just prior to the Peninsula Campaign. The General Washington Parke Custis , a converted coal barge, had its deck cleared of all items that could entangle the ropes and nets of the balloons, and it was used as a river transport for the Corps. Lowe had two gas generators and a balloon loaded aboard and later reported: I have the pleasure of reporting the complete success of the first balloon expedition by water ever attempted. I left

11600-540: The Washington , and the larger Intrepid , used the waterways to make its way inland. In mid May 1862, Lowe arrived at the White House on the Pamunkey River . This is the first home of George and Martha Washington , after which the Washington presidential residence is named. At this time, it was the home of the son of Robert E. Lee , whose family fled at the arrival of Lowe. Lowe was met by McClellan's Army

11800-435: The regimental colors and rallied their fellow soldiers to fight, provided first aid or helped the wounded back to a field hospital. A related (and sometimes conflated) role was that of "daughter of the regiment". Often literally a daughter of one of the regimental officers, these women looked to the soldiers' well-being but also served as their regiment's "mascot" who inspired the men by wearing stylish clothing and enduring

12000-443: The volunteer units . The pre-war regular army numbered approximately 16,400 soldiers, but by the end while the Union army had grown to over a million soldiers, the number of regular personnel was still approximately 21,699, of whom several were serving with volunteer forces. Only 62,000 commissions and enlistments in total were issued for the regular army during the war as most new personnel preferred volunteer service. Since before

12200-471: The 1850s until well into the 20th century, British submarine cable systems dominated the world system. This was set out as a formal strategic goal, which became known as the All Red Line . In 1896, there were thirty cable-laying ships in the world and twenty-four of them were owned by British companies. In 1892, British companies owned and operated two-thirds of the world's cables and by 1923, their share

12400-530: The 1890s saw the discovery and then development of a newly understood phenomenon into a form of wireless telegraphy , called Hertzian wave wireless telegraphy, radiotelegraphy, or (later) simply " radio ". Between 1886 and 1888, Heinrich Rudolf Hertz published the results of his experiments where he was able to transmit electromagnetic waves (radio waves) through the air, proving James Clerk Maxwell 's 1873 theory of electromagnetic radiation . Many scientists and inventors experimented with this new phenomenon but

12600-647: The Adjutant General's department under Simeon Draper , it was made an independent department in its own right on May 1, 1863, under James B. Fry . The Signal Corps was created and deployed for the first time, through the leadership of Albert J. Myer . One drawback to this system was that the authority and responsibilities of the Secretary of War, his Assistant Secretaries , and the General-in-Chief were not clearly delineated. Additionally,

12800-464: The Allen brothers, who had lost their own balloon when they were vying for the top job; two men the Allen brothers recommended, Eben Seaver and J. B. Starkweather; William Paullin , an older Philadelphia colleague; German balloonist John Steiner; and Ebenezer Mason, Lowe's construction supervisor, who requested active duty. Lowe set up several locations for the balloons—Fort Monroe, Washington D.C., Camp Lowe near Harpers Ferry —but always kept himself at

13000-642: The Army Quartermaster. He was essentially out of a job. Lowe was ordered to join the Army for the Battle of Antietam , but he did not reach the battlefield until after the Confederates began their retreat to Virginia. Lowe had to reintroduce himself to the new commanding general of the Army of the Potomac, Ambrose Burnside , who activated Lowe at the Battle of Fredericksburg . For all its success,

13200-452: The Army when the airship (a dirigible, blimp , or zeppelin ) came into existence with their motorized propulsion and mechanical means of steering. The United States Army Signal Corps established a War Balloon Company in 1893 at Fort Riley , Kansas (at the time, home of the Signal School), and the next year at Fort Logan , Colorado, using a single balloon (the General Myer ) purchased in France. When that balloon deteriorated, members of

13400-411: The Balloon Corps was never fully appreciated by the military community. The ballonists were still regarded as carnival showmen. Others had little respect for their break-neck operation. The only ones who found any value in them were the generals whose jobs and reputations were on the line. Lower-ranking administrators looked with disdain on this band of civilians who, as they perceived them, had no place in

13600-427: The British government followed—by March 1897, Marconi had transmitted Morse code signals over a distance of about 6 km ( 3 + 1 ⁄ 2  mi) across Salisbury Plain . On 13 May 1897, Marconi, assisted by George Kemp, a Cardiff Post Office engineer, transmitted the first wireless signals over water to Lavernock (near Penarth in Wales) from Flat Holm . His star rising, he was soon sending signals across

13800-438: The Civil War was a hazardous occupation: grueling hours spent in close proximity to deadly diseases and nearby battlefields resulted in many suffering permanent disabilities or death. Added to this were the prejudices of the male medical officers in charge who did not want them there and frequently clashed with the nurses over issues of triage , patient treatments and hospice care . Tens of thousands of women served as nurses for

14000-411: The Civil War, the American public had a generally negative view of the nation's armed forces, attributable to a Jeffersonian ideal which saw standing armies as a threat to democracy and instead valorized the " citizen soldier " as being more in keeping with American ideals of equality and rugged individualism . This attitude remained unchanged during the Civil War, and afterwards many would attribute

14200-400: The Confederacy to make a balloon. It was done and soon we had a great patchwork ship ... for use in the Seven Days campaign . One day it was on a steamer down the James River when the tide went out and left it high and dry on a [sand]bar. The Federals gathered it in, and with it the last silk dress in the Confederacy. This was the meanest trick of the war ... The silk material balloon used by

14400-488: The Confederate Army. McClellan felt that the Confederates were simply feigning an attack. Lowe could see, from his better vantage point, that they were converging on Heintzelman's position. Heintzelman was cut off from the main body because the swollen river had taken out all the bridges. Lowe sent urgent word of Heintzelman's predicament and recommended immediate repair of New Bridge and reinforcements for him. At

14600-582: The Confederate cause during the Civil War were known as Southern Unionists . They were also known as Union Loyalists or Lincoln's Loyalists. Within the eleven Confederate states, states such as Tennessee (especially East Tennessee ), Virginia (which included West Virginia at the time), and North Carolina were home to the largest populations of Unionists. Many areas of Southern Appalachia harbored pro-Union sentiment as well. As many as 100,000 men living in states under Confederate control would serve in

14800-403: The Confederates was of a design by Dr. Edward Cheves of Savannah, Georgia. Cheves had the silk material sewn together by seamstresses and then covered the silk material with a varnish made by melting rubber in oil. The balloon was filled with a coal gas and launched from a railroad car that its pilot, Edward Porter Alexander , had positioned near the battlefield. In late June 1862, Alexander made

15000-645: The Great Wall. Signal towers away from the wall were used to give early warning of an attack. Others were built even further out as part of the protection of trade routes, especially the Silk Road . Signal fires were widely used in Europe and elsewhere for military purposes. The Roman army made frequent use of them, as did their enemies, and the remains of some of the stations still exist. Few details have been recorded of European/Mediterranean signalling systems and

15200-466: The Morse system connected Baltimore to Washington , and by 1861 the west coast of the continent was connected to the east coast. The Cooke and Wheatstone telegraph , in a series of improvements, also ended up with a one-wire system, but still using their own code and needle displays . The electric telegraph quickly became a means of more general communication. The Morse system was officially adopted as

15400-582: The Navy yard early Sunday morning ... having on board competent assistant aeronauts, together with my new gas generating apparatus, which, though used for the first time, worked admirably. The battlefront turned toward Richmond in the Peninsula Campaign . The heavy forestation inhibited the use of balloons, so Lowe and his Balloon Corps, with the use of three of his balloons, the Constitution ,

15600-488: The Scandinavian Regiment (15th Wisconsin). But for the most part, the foreign-born soldiers were scattered as individuals throughout units. The Confederate army was less diverse: 91% of its soldiers were native-born white men and only 9% were foreign-born white men, with Irish being the largest group, other groups included Germans, French, British, and Mexicans. Most Mexicans happened to have been born when

15800-449: The Secretary where his usual transcriptions of messages were lacking. Free flight would almost always require the aeronaut to return and make a report. This would be an obvious detriment to timely reporting. LaMountain and Lowe had long argued over free flight and captive flight. In Lowe's first instance of demonstration at Bull Run, he made a free flight which caught him hovering over Union encampments who could not properly identify him. As

16000-634: The South but the Border States too. However he eventually changed his mind and persuaded Congress to authorize the first official Black enlistment system in late 1862, which evolved into the United States Colored Troops . Before they were allowed to enlist, many Black people volunteered their services to the Union army as cooks, nurses, and in other informal roles, and several volunteer regiments of Black troops were raised by

16200-402: The Topographical Engineers told Lowe that Wise was preparing to bring up his own balloon, supposedly the Atlantic. Other accounts state that John LaMountain had taken possession of the Atlantic after a failed flight he made with Wise in 1859, and later place the Atlantic with LaMountain at Fort Monroe. Lowe's report says that Captain Whipple indicated they had instructed Mr. Wise to construct

16400-496: The Union Army reduced its use of balloons, so did the Confederates. During the Seven Days Battles in late June, McClellan's army was forced to retreat from the outskirts of Richmond. Lowe returned to Washington and he contracted malaria in the swampy conditions and was out of service for a little more than a month. When he returned to duty, he found that all his wagons, mules, and service equipment had been returned to

16600-431: The Union Army. Also vying for the position were Prof. John Wise, Prof. John LaMountain, and Ezra and James Allen. All these men were aeronauts of extraordinary qualification in aviation of the day. Among them Lowe stood out as the most successful in balloon building and the closest to making a transatlantic flight. His scientific record was held in high regard among colleagues of the day, to include one Prof. Joseph Henry of

16800-616: The Union army (including generals Edward Ferrero and Francis B. Spinola ). Six Italian Americans received the Medal of Honor during the war, among whom was Colonel Luigi Palma di Cesnola , who later became the first Director of the Metropolitan Museum of Arts in New York (1879–1904). Most of the Italian-Americans who joined the Union army were recruited from New York City . Many Italians of note were interested in

17000-421: The Union army in maintaining the order and alignment of formations during marches, battles, and transitioning between the two. Sergeants in particular were vital in this role as general guides and their selection ideally reserved for the most distinguished soldiers. NCOs were also charged with training individuals in how to be soldiers. While the captain or other company-level officers were responsible for training

17200-420: The Union army or pro-Union guerilla groups. Although Southern Unionists came from all classes, most differed socially, culturally, and economically from the region's dominant pre-war planter class . Native-born White Americans made up roughly two-thirds of the soldiers in the Union army, with the rest of many different ethnic groups, including large numbers of immigrants. About 25% of the white men who served in

17400-482: The Union army were foreign-born. The U.S. experienced its heaviest rate of immigration during the 1850s, and the vast majority of these people moved to the Northeastern states. Among these immigrants, Germans constituted the largest group with a million arrivals between 1850 and 1860, many of them Forty-Eighters . Nearly as many Irish immigrants arrived during the same period. Immigrant soldiers were among

17600-408: The Union army, among whom are included Clara Barton , Susie King Taylor , Mary Edwards Walker , and Louisa May Alcott . No less vital were the thousands of women who provided service to the Union army in the field of espionage . Early in the war, women were at a distinct advantage as spies , scouts , smugglers , and saboteurs : the idea of women participating in such dangerous lines of work

17800-470: The Union army. He established a military school in New York City where many young Italians were trained and later served in the Union army. Di Cesnola received the Medal of Honor for his actions during the Battle of Aldie . Two more famous examples were Francesco Casale and Luigi Tinelli, who were instrumental in the formation of the 39th New York Infantry Regiment . According to one evaluation of

18000-474: The Union army. An estimated 100,000 white soldiers from states within the Confederacy served in Union army units. Between April 1861 and April 1865, at least 2,128,948 men served in the United States Army, of whom the majority were volunteers. It is a misconception that the South held an advantage because of the large percentage of professional officers who resigned to join the Confederate army. At

18200-457: The Union's victory to the volunteers rather than the leadership and staff work provided by the regular army. In return, officers of the regular army despised the militia and saw them as having dubious value. Commentators such as Emory Upton would later argue that the reliance on militia for the nation's defense was responsible for prolonging conflicts and making them more expensive in both money and lives spent. Despite these attitudes towards

18400-472: The United States Army was based on the traditions developed in Europe, with the regiment being the basis of recruitment, training and maneuvering. However, for a variety of reasons there could be vast differences in the number of actual soldiers organized even into units of the same type. Changes in how units were structured during the course of the war, contrasts in organizational principals between regular and volunteer units, and even simple misnaming all played

18600-402: The United States, and with a shortage of soldiers in the army, President Abraham Lincoln called on the states to raise a force of 75,000 troops for three months to put down the Confederate insurrection and defend the national capital in Washington, D.C. Lincoln's call forced the border states to choose sides, and four seceded, making the Confederacy eleven states strong. It turned out that

18800-530: The air. In another incident, one of the handlers became entangled in the ascending tether rope which had to be chopped loose, leaving the captain free-flying over his own Confederate positions whose troops threatened to shoot him down. Attempts at making gas-filled silk balloons were hampered by the South's inability to obtain any imports. They did fashion a balloon from dress silk. Evans cites excerpts from Confederate letters that stated their balloons were made from dress-making silk and not dresses themselves. As it

19000-419: The argument, but Lowe's position as Chief Aeronaut allowed him to prevail. Lowe believed that balloons used for military purposes had to be better constructed than the common balloons used by civilian aeronauts. They also required special handling and care for use on the battlefield. At first the balloons of the day were inflated at municipal coke gas supply stations and were towed inflated by ground crews to

19200-573: The attention of General Benjamin Butler at Fort Monroe . LaMountain operated at Fort Monroe for a while with the battered Atlantic and was actually accredited with having made the first effective wartime observations from an aerial position. He also obtained use of a balloon, the Saratoga , which he soon lost in a windstorm. LaMountain advocated free flight balloon reconnaissance, whereas Lowe used captive or tethered flight, remaining always attached to

19400-624: The balloon. On Saturday, 16 June, with his own balloon, the Enterprise , Lowe ascended some 500 feet (150 m) above the Columbian Armory with a telegraph key and operator, and a wire following a tether line to the White House across the street. From aloft he transmitted the message: Balloon Enterprise Washington, June 16 1861 To President United States: This point of observation commands an area nearly fifty miles in diameter. The city with its girdle of encampments presents

19600-519: The battle front. He served General McClellan at Yorktown until the Confederates retreated toward Richmond . The heavily forested Virginia Peninsula forced him to take to the waterways. Balloon service was requested at more remote locations as well. Eben Seaver was assigned to take the Eagle to the Mississippi River to assist in battlefronts there. Mr. Starkweather was sent to Port Royal with

19800-466: The battlefield at Bull Run . McDowell became impressed with Lowe and his balloon, and a good word reached the President, who personally introduced Lowe to Union General-in-Chief Winfield Scott . "General, this is my friend Professor Lowe who is organizing an aeronautics corps and who is to be its chief. I wish you would facilitate his work in every way." This introduction fairly well settled the selection of Lowe as Chief Aeronaut. The details of establishing

20000-451: The colors. There were a number of staff NCO positions including quartermaster sergeant , ordnance sergeant , and commissary sergeant. NCOs in the volunteer forces were quite different from their regular counterparts as the war began. Appointed to their role as each regiment was created, they were often on a first-name basis with both their superior officers and the enlisted men they were tasked to lead. Discipline among friends and neighbors

20200-405: The commanding generals through a process of trial and error based on the best recommendations of the balloonists themselves. Of those seeking the position, only two were given actual opportunities to perform combat aerial reconnaissance, Prof. Thaddeus Lowe and Mr. John LaMountain . Professor Thaddeus S. C. Lowe was one of the top American balloonists who sought the position of Chief Aeronaut for

20400-582: The company sewed together a silk replacement in 1897. The balloon, dubbed the Santiago , saw limited use in combat in 1898 during the Spanish–American War . Reports of Lowe's work in aeronautics and aerial reconnaissance were heard abroad. In 1864, Lowe was offered a Major-General position with the Brazilian Army , which was at war with Paraguay , but he turned it down. In the 19th century,

20600-438: The consensus was that these new waves (similar to light) would be just as short range as light, and, therefore, useless for long range communication. At the end of 1894, the young Italian inventor Guglielmo Marconi began working on the idea of building a commercial wireless telegraphy system based on the use of Hertzian waves (radio waves), a line of inquiry that he noted other inventors did not seem to be pursuing. Building on

20800-411: The coordinates of the letter of the alphabet being transmitted. The number of said torches held up signalled the grid square that contained the letter. There is no definite record of the system ever being used, but there are several passages in ancient texts that some think are suggestive. Holzmann and Pehrson, for instance, suggest that Livy is describing its use by Philip V of Macedon in 207 BC during

21000-400: The corps and its method of operation were left up to Lowe. The misunderstanding that the Balloon Corps would remain a civilian contract lasted its duration, and neither Lowe nor any of his men ever received commissions. John Wise was an early pioneer of American ballooning born in 1808. Although he made great contributions to the then newborn science of aeronautics, he was more a showman than

21200-458: The earliest electrical telegraphs. A telegraph message sent by an electrical telegraph operator or telegrapher using Morse code (or a printing telegraph operator using plain text) was known as a telegram. A cablegram was a message sent by a submarine telegraph cable, often shortened to "cable" or "wire". The suffix -gram is derived from ancient Greek: γραμμα ( gramma ), meaning something written, i.e. telegram means something written at

21400-486: The effective use of field artillery. On 24 September 1861, he was directed to position himself at Fort Corcoran , just across the Potomac river, west of Washington, to ascend and overlook the Confederate encampments at Falls Church, Virginia, at a distance further west. A concealed Union artillery battery was remotely located at Camp Advance. Lowe was to give flag signal directions to the artillery, who would fire blindly on Falls Church. Each signal would indicate adjustments to

21600-495: The efforts of the Confederate States Army . Over the course of the war, 2,128,948 men enlisted in the Union army, including 178,895, or about 8.4% being colored troops ; 25% of the white men who served were immigrants, and a further 18% were second-generation Americans. 596,670 Union soldiers were killed, wounded or went missing during the war. The initial call-up in 1861 was for just three months, after which many of these men chose to reenlist for an additional three years. When

21800-445: The efforts of the four "supply" departments (Quartermaster, Subsistence, Ordnance & Medical) were not coordinated with each other, a condition that would last throughout the war. Although the "War Board" could provide military advice and help coordinate military policy, it was not until the appointment of Ulysses Grant as General-in-Chief was there more than the vaguest coordination of military strategy and logistics. The Union army

22000-493: The end of the war, prominent examples include Harriet Tubman , Mary Louvestre , Pauline Cushman , Elizabeth Van Lew , and Mary Bowser . In his 1997 book examining the motivations of the American Civil War's soldiers, For Cause and Comrades , historian James M. McPherson states that Union soldiers fought to preserve the United States, as well as to end slavery, stating that: Telegraph Telegraphy

22200-537: The erroneous belief that there was an electrified atmospheric stratum accessible at low altitude. They thought atmosphere current, connected with a return path using "Earth currents" would allow for wireless telegraphy as well as supply power for the telegraph, doing away with artificial batteries. A more practical demonstration of wireless transmission via conduction came in Amos Dolbear 's 1879 magneto electric telephone that used ground conduction to transmit over

22400-415: The extensive definition used by Chappe, Morse argued that the term telegraph can strictly be applied only to systems that transmit and record messages at a distance. This is to be distinguished from semaphore , which merely transmits messages. Smoke signals, for instance, are to be considered semaphore, not telegraph. According to Morse, telegraph dates only from 1832 when Pavel Schilling invented one of

22600-537: The field operations of the army. At the start of the war, Simon Cameron served as Secretary of War before being replaced in January 1862 by Edwin Stanton . The role of general-in-chief was filled by several men during the course of the war: The gap from March 11 to July 23, 1862, was filled with direct control of the army by President Lincoln and Secretary Stanton, with the help of an unofficial "War Board" that

22800-428: The field. Lowe recognized the need for the development of portable hydrogen gas generators, by which the balloons could be filled in the field. Lowe had to deal with administrative officers who usually held ranks lower than major and had more interest in accounting than providing for a proper war effort. This caused delays in the funding of materials. Lowe was called out for another demonstration mission that would change

23000-508: The fight against Geronimo and other Apache bands in the Apache Wars . Miles had previously set up the first heliograph line in the US between Fort Keogh and Fort Custer in Montana . He used the heliograph to fill in vast, thinly populated areas that were not covered by the electric telegraph. Twenty-six stations covered an area 320 by 480 km (200 by 300 mi). In a test of the system,

23200-623: The first commercial service to transmit nightly news summaries to subscribing ships, which could incorporate them into their on-board newspapers. A regular transatlantic radio-telegraph service was finally begun on 17 October 1907. Notably, Marconi's apparatus was used to help rescue efforts after the sinking of RMS  Titanic . Britain's postmaster-general summed up, referring to the Titanic disaster, "Those who have been saved, have been saved through one man, Mr. Marconi...and his marvellous invention." The successful development of radiotelegraphy

23400-651: The ground without any wires connecting the stations. Other attempts were made to send the electric current through bodies of water, to span rivers, for example. Prominent experimenters along these lines included Samuel F. B. Morse in the United States and James Bowman Lindsay in Great Britain, who in August 1854, was able to demonstrate transmission across a mill dam at a distance of 500 yards (457 metres). US inventors William Henry Ward (1871) and Mahlon Loomis (1872) developed electrical conduction systems based on

23600-467: The idea of dropping ordnance on the enemy from an aerial station was not seriously considered, although there was a patent issued to a Charles Perley in February 1863 for a bomb-dropping device that could be floated aloft by balloon. The balloon bomb was to be unmanned, and the plan was a theory which had no effective way of assuring that a bomb could be delivered and dropped remotely on the enemy. Also, as

23800-419: The ideas of previous scientists and inventors Marconi re-engineered their apparatus by trial and error attempting to build a radio-based wireless telegraphic system that would function the same as wired telegraphy. He would work on the system through 1895 in his lab and then in field tests making improvements to extend its range. After many breakthroughs, including applying the wired telegraphy concept of grounding

24000-435: The job too unsuitable for women of social rank, particularly at the thought of unmarried women surrounded by thousands of men in close quarters. Nevertheless, Congress eventually approved for women to serve as nurses, to which Dorothea Dix – appointed Superintendent of Army Nurses – was responsible for setting hiring guidelines and starting a training program for prospective candidates. For the women who served, nursing during

24200-561: The largest ship of its day, designed by Isambard Kingdom Brunel . An overland telegraph from Britain to India was first connected in 1866 but was unreliable so a submarine telegraph cable was connected in 1870. Several telegraph companies were combined to form the Eastern Telegraph Company in 1872. Australia was first linked to the rest of the world in October 1872 by a submarine telegraph cable at Darwin . From

24400-420: The left, to the right, long or short. Simultaneously reports were telegraphed down to headquarters at the fort. With only a few corrections, the battery was soon landing rounds right on target. This was the precursor to the use of the artillery forward observer (FO). The next day, Lowe received orders to build four proper balloons with hydrogen gas generators. Lowe went to work at his Philadelphia facility. He

24600-415: The letter post on price, and competition from the telephone , which removed their speed advantage, drove the telegraph into decline from 1920 onwards. The few remaining telegraph applications were largely taken over by alternatives on the internet towards the end of the 20th century. The word telegraph (from Ancient Greek : τῆλε ( têle ) 'at a distance' and γράφειν ( gráphein ) 'to write')

24800-421: The line at his own expense and agreed that the railway could have free use of it in exchange for the right to open it up to the public. Most of the early electrical systems required multiple wires (Ronalds' system was an exception), but the system developed in the United States by Morse and Vail was a single-wire system. This was the system that first used the soon-to-become-ubiquitous Morse code . By 1844,

25000-603: The military. Furthermore, none of the corps ever received a military commission, leaving them facing the dangers of being captured and treated as spies, summarily punishable by death. The Balloon Corps was eventually assigned to the Army Corps of Engineers and put under the administrative purview of one Captain Cyrus B. Comstock , who did not appreciate a civilian (Lowe) being paid more than he. He reduced Lowe's pay from $ 10 gold to $ 6 currency (equal to $ 3 gold) per day. Lowe posted

25200-624: The modern International Morse code) to aid differentiating from the morse dot. Use of the heliograph declined from 1915 onwards, but remained in service in Britain and British Commonwealth countries for some time. Australian forces used the heliograph as late as 1942 in the Western Desert Campaign of World War II . Some form of heliograph was used by the mujahideen in the Soviet–Afghan War (1979–1989). A teleprinter

25400-462: The most enthusiastic in the Union army, not only from a desire to help save their adoptive home but to prove their patriotism towards it. To help cement immigrant enthusiasm and loyalty to the Union, several generals were appointed from these communities, including Franz Sigel and Michael Corcoran . Many immigrant soldiers formed their own regiments, such as the Irish Brigade , including

25600-426: The necessity of leading their units into combat and their conspicuousness when accompanied by staff and escorts. Among memorable field leaders of the army were Nathaniel Lyon (first Union general to be killed in battle during the war), William Rosecrans , George Henry Thomas , William Tecumseh Sherman , and Phil Sheridan . Others include Benjamin F. Butler . Non-commissioned officers (NCOs) were important in

25800-672: The notion that Black soldiers were a liability, allowing about 200,000 Black soldiers to serve in the Union army during the Civil War. Even as they served their country, Black soldiers were subject to discrimination. They were more often assigned to menial labor. Some Union officers refused to employ them in combat, but when they were they often had to use inferior weapons and equipment. Black soldiers were paid less than white soldiers ($ 10 vs $ 16 per month) until Congress yielded to public pressure and approved equal pay in June 1864. Black units were led predominantly by white officers, and while more than

26000-406: The other men in the Corps. Lowe lodged a formal complaint to Gen. George B. McClellan , and by February 1862 LaMountain was discharged from military service. There were two methods of piloting balloons: free flight or captive. Free flight meant that the balloon was able to travel in any direction or distance for as long or as far as the pilot was able to fly it. Captive flight meant that the balloon

26200-491: The outbreak of the American Civil War, Giuseppe Garibaldi was a very popular figure. The 39th New York Volunteer Infantry Regiment , of whose 350 members were Italian, was nicknamed Garibaldi Guard in his honor. The unit wore red shirts and bersaglieri plumes . They carried with them both a Union Flag as well as an Italian flag with the words Dio e popolo, meaning "God and people." In 1861 Garibaldi himself volunteered his services to President Abraham Lincoln . Garibaldi

26400-479: The outbreak of the Civil War. This group's loyalties were far more evenly divided. Clayton R. Newell (2014) states, 92 wore Confederate gray and 102 put on the blue of the United States Army. Hattaway and Jones (1983), John and David Eicher (2001), and Jennifer M. Murray (2012), state that 99 joined the Confederate army and 114 returned to the Union forces. With the Southern slave states declaring secession from

26600-418: The position, and Lowe was at last unencumbered from taking up the task. Lowe describes the inflation incident in his official report less dramatically, saying that he was told by the gas plant supervisor to disconnect and let another balloon go first. Lowe did not name names, but it is not likely that it was anyone other than Wise. Lowe's report about a new balloon has to be considered over Hoehling's account of

26800-399: The possible messages. One of the few for which details are known is a system invented by Aeneas Tacticus (4th century BC). Tacticus's system had water filled pots at the two signal stations which were drained in synchronisation. Annotation on a floating scale indicated which message was being sent or received. Signals sent by means of torches indicated when to start and stop draining to keep

27000-534: The regulars' performance could impress even the most battle-hardened volunteers. At The Wheatfield during the Battle of Gettysburg , the regulars' fighting skill and orderly retirement under fire drew the admiration of many observers, including Prince Philippe, Count of Paris . As one volunteer put it, "For two years the U.S. Regulars taught us how to be soldiers [;] in the Wheatfield at Gettysburg, they taught us how to die like soldiers." The regulars became

27200-406: The regulars, they would serve as an important foundation around which the Union army was built. In the disastrous First Battle of Bull Run , it was the regulars who acted as rearguard during the retreat while the volunteers fled, and when George McClellan was put in charge of what became the Army of the Potomac he used regular officers and non-commissioned officers to train the volunteers. Training

27400-415: The restoration and preservation of the United States as a working, viable republic. The Union Army was made up of the permanent regular army of the United States , but further fortified, augmented, and strengthened by the many temporary units of dedicated volunteers , as well as including those who were drafted in to service as conscripts . To this end, the Union army fought and ultimately triumphed over

27600-402: The same grade regardless of their date of commission, a feature which could have become a subject of contention. The use of brevet ranks was also a common feature of the Union army. Officer appointments depended on the commission grade and whether it was in the regular or volunteer forces. The President reserved the right to issue commission for all regular officers and for general officers in

27800-511: The same hardships as them. Some of the most prominent women to accompany the Union armies in the field include Anna Etheridge , Marie Tepe , and Nadine Turchin . Women also sought to serve more formally as nurses in the Union army, many having been inspired by the work of Florence Nightingale during the Crimean War . However, there was strong resistance against these efforts at first. Societal prejudices saw women as too delicate and

28000-419: The same run of tape. The advantage of doing this is that messages can be sent at a steady, fast rate making maximum use of the available telegraph lines. The economic advantage of doing this is greatest on long, busy routes where the cost of the extra step of preparing the tape is outweighed by the cost of providing more telegraph lines. The first machine to use punched tape was Bain's teleprinter (Bain, 1843), but

28200-430: The same time, he sent over an order for the inflation of the Intrepid , a larger balloon that could take him higher with telegraph equipment, in order to oversee the imminent battle. When Lowe arrived from Mechanicsville to the site of the Intrepid at Gaines' Mill, he saw that the aerostat's envelope was an hour away from being fully inflated. He then called for a camp kettle to have the bottom cut out of it, and he hooked

28400-406: The soldiers when assembled into squads, platoons or as a company, experienced NCOs could take over this training as well. NCOs were also responsible for the regimental colors , which helped the unit maintain formation and serve as a rally point for the regiment. Typically a sergeant was designated the standard-bearer and protected by a color guard of corporals who only opened fire in defense of

28600-455: The speed of recording ( Bain , 1846), but was delayed by a patent challenge from Morse. The first true printing telegraph (that is printing in plain text) used a spinning wheel of types in the manner of a daisy wheel printer ( House , 1846, improved by Hughes , 1855). The system was adopted by Western Union . Early teleprinters used the Baudot code , a five-bit sequential binary code. This

28800-592: The standard by which the Volunteers were measured, and to be described as being as good or better than them was considered the highest compliment. Commissioned officers in the Union army could be divided in several categories: general officers , including lieutenant general , which was added on March 2, 1864, major generals and brigadier generals ; field officers including colonels , lieutenant colonels and majors ; and company officers including captains , first lieutenants and second lieutenants . There

29000-579: The standard for continental European telegraphy in 1851 with a revised code, which later became the basis of International Morse Code . However, Great Britain and the British Empire continued to use the Cooke and Wheatstone system, in some places as late as the 1930s. Likewise, the United States continued to use American Morse code internally, requiring translation operators skilled in both codes for international messages. Railway signal telegraphy

29200-420: The start of the war, there were 824 graduates of the U.S. Military Academy on the active list; of these, 296 resigned or were dismissed, and 184 of those became Confederate officers. Of the approximately 900 West Point graduates who were then civilians, 400 returned to the U.S. Army and 99 to the Confederacy. The ratio of U.S. Army to Confederate professional officers was 642 to 283. One of the resigning officers

29400-498: The states. These included the 1st Kansas Colored Infantry Regiment , the first Black regiment to be raised and the first to engage in combat; the 1st Louisiana Native Guard , raised from both freedmen and escaped slaves after the Capture of New Orleans ; and the 54th Massachusetts Infantry Regiment , which became the most famous Black unit after their valiant participation in the Battle of Fort Wagner . Their efforts helped to dispel

29600-413: The sudden appearance of John Wise who demanded that Lowe stop his inflating of the Enterprise and let him inflate his balloon instead. Wise had legal papers upholding his purported authority. Although Wise's arrival on the scene was tardy, he did inflate his balloon and proceeded toward the battlefield. On the way the balloon became caught in the brush and was permanently disabled. This ended Wise's bid for

29800-462: The synchronisation. None of the signalling systems discussed above are true telegraphs in the sense of a system that can transmit arbitrary messages over arbitrary distances. Lines of signalling relay stations can send messages to any required distance, but all these systems are limited to one extent or another in the range of messages that they can send. A system like flag semaphore , with an alphabetic code, can certainly send any given message, but

30000-559: The system is designed for short-range communication between two persons. An engine order telegraph , used to send instructions from the bridge of a ship to the engine room, fails to meet both criteria; it has a limited distance and very simple message set. There was only one ancient signalling system described that does meet these criteria. That was a system using the Polybius square to encode an alphabet. Polybius (2nd century BC) suggested using two successive groups of torches to identify

30200-619: The system saw only limited use. Later versions of Bain's system achieved speeds up to 1000 words per minute, far faster than a human operator could achieve. The first widely used system (Wheatstone, 1858) was first put into service with the British General Post Office in 1867. A novel feature of the Wheatstone system was the use of bipolar encoding . That is, both positive and negative polarity voltages were used. Bipolar encoding has several advantages, one of which

30400-477: The telegraph was almost always necessary. At closer altitudes a series of prepared flag signals, hand signals, or even a megaphone could be used to communicate with the ground. At night either the telegraph or lamps could be used. In the later battles of Lowe's tenure, all reports and communications were ordered to be made orally by ascending and descending with the balloon. This is notable in Lowe's Official Report II to

30600-478: The towing handlers crawl over the bridge beams and stringers to cross the upper Potomac River into Fairfax County . The balloon and crew arrived by daylight, exhausted from the nine-hour overnight ordeal, when a gale-force wind took the balloon away. It was later recovered, but not before Lowe, who was humiliated by the incident, went on a tirade about the delays in providing proper equipment. Lowe built seven balloons, six of which were put into service. Each balloon

30800-537: The transmitter and receiver, Marconi was able, by early 1896, to transmit radio far beyond the short ranges that had been predicted. Having failed to interest the Italian government, the 22-year-old inventor brought his telegraphy system to Britain in 1896 and met William Preece , a Welshman, who was a major figure in the field and Chief Engineer of the General Post Office . A series of demonstrations for

31000-445: The two stations to form a complete electrical circuit or "loop". In 1837, however, Carl August von Steinheil of Munich , Germany , found that by connecting one leg of the apparatus at each station to metal plates buried in the ground, he could eliminate one wire and use a single wire for telegraphic communication. This led to speculation that it might be possible to eliminate both wires and therefore transmit telegraph signals through

31200-405: The valve ends of the Intrepid and the Constitution together. He had the gas of the Constitution transferred to the Intrepid and was up in the air in 15 minutes. From this new vantage point, Lowe was able to report on all the Confederate movements. McClellan took Lowe's advice, repaired the bridge, and had reinforcements sent to Heintzelman's aid. An account of the battle was being witnessed by

31400-835: The visiting Count de Joinville who at day's end addressed Lowe with: "You, sir, have saved the day!" Because of the effectiveness of the Union Army Balloon Corps, the Confederates felt compelled to incorporate balloons as well. Since coke gas was not readily available in Richmond, the first balloons were made of the Montgolfier rigid style: cotton stretched over wood framing and filled with hot smoke from fires made of oil-soaked pine cones. They were piloted by Captain John R. Bryan for use at Yorktown. Bryan's handlers were poorly experienced, and his balloon began spinning in

31600-525: The volunteer forces. volunteer field and company-grade officers could be commissioned by either the president or their respective governor. Company officers were also unique in that they were usually elected by members of their company. The political appointment and/or election of volunteer officers was part of a long-standing militia tradition and of a political patronage system common in the United States. While many of these officers were West Point graduates or had prior military experience, others had none, nor

31800-411: The volunteers, especially in regards to critical administrative and logistical matters, remained an important function of the regulars during the war. This was particularly the case with regular army artillery, as they were more widely dispersed than the infantry and cavalry (making them more visible to the olunteers) and were assigned to specific units to train their volunteer counterparts. In battle,

32000-404: The war and joined the army, reaching positions of authority. Brigadier General Edward Ferrero was the original commander of the 51st New York Regiment . He commanded both brigades and divisions in the eastern and western theaters of war and later commanded a division of the United States Colored Troops . Colonel Enrico Fardella, of the same and later of the 85th New York regiment, was made

32200-400: The war itself proved to be much longer and far more extensive in scope and scale than anyone on either side, Union North or Confederate South, expected or even imagined at the outset on the date of July 22, 1861. That was the day that Congress initially approved and authorized subsidy to allow and support a volunteer army of up to 500,000 troops to the cause. The call for volunteers initially

32400-452: The wives or other female relatives of the soldiers themselves who saw to their personal needs and (if time allowed) looked to the well-being of other soldiers. A somewhat more formal role for some camp followers was that of vivandière . Originally a female sutler , the role of vivandière expanded to include other responsibilities, including on the battlefield. Armed for their own protection, they brought water to thirsty soldiers, carried

32600-508: Was Michigan , which designated Fort Wayne as a training center for both officers and NCOs. As the war progressed NCOs gained valuable experience and even drastic disciplinary measures such as execution by firing squad were carried out when deemed necessary. The promotion of soldiers to NCOs (and NCOs to officers) was also increasingly based on battlefield performance, although each state maintained their own standards for when and where promotions could be granted. Southerners who were against

32800-758: Was Robert E. Lee , who initially was offered the assignment as commander of a field army to suppress the rebellion. Lee disapproved of secession, but refused to bear arms against his native state, Virginia , and resigned to accept the position as commander of the Virginian Confederate forces. Lee eventually became the overall commander of the Confederate army. The Confederacy had the advantage of having several military colleges, including The Citadel and Virginia Military Institute , but they produced fewer officers. Though officers were able to resign, enlisted soldiers did not have this right. As they usually had to either desert or wait until their enlistment term

33000-459: Was a competitor to electrical telegraphy using submarine telegraph cables in international communications. Telegrams became a popular means of sending messages once telegraph prices had fallen sufficiently. Traffic became high enough to spur the development of automated systems— teleprinters and punched tape transmission. These systems led to new telegraph codes , starting with the Baudot code . However, telegrams were never able to compete with

33200-455: Was a success as a reconnaissance flight with LaMountain being able to go where he would. But on his return he was threatened by Union troops who could not identify him. His balloon was shot down, and LaMountain was treated harshly until he was clearly identified. Lowe considered the incident an argument against free flight. LaMountain insisted that the flight was highly successful despite the unfortunate incident. The showdown did nothing to settle

33400-485: Was a telegraph code developed for use on the French telegraph using a five-key keyboard ( Baudot , 1874). Teleprinters generated the same code from a full alphanumeric keyboard. A feature of the Baudot code, and subsequent telegraph codes, was that, unlike Morse code, every character has a code of the same length making it more machine friendly. The Baudot code was used on the earliest ticker tape machines ( Calahan , 1867),

33600-418: Was accompanied by two gas generating sets. The smaller balloons were used in windier weather, or for quick, one-man, low altitude ascents. They inflated quickly since they required less gas. They were: The larger balloons were used for carrying more weight, such as a telegraph key set and an additional man as an operator. They could also ascend higher. They were: The latter two balloons were held in storage in

33800-474: Was appointed Ingénieur-Télégraphiste and charged with establishing a line of stations between Paris and Lille , a distance of 230 kilometres (140 mi). It was used to carry dispatches for the war between France and Austria. In 1794, it brought news of a French capture of Condé-sur-l'Escaut from the Austrians less than an hour after it occurred. A decision to replace the system with an electric telegraph

34000-457: Was authorized a number of aides-de-camp as their personal staff and a general staff . The general staff included representatives of the other combat arms, such as a chief of artillery and chief of cavalry (the infantry being typically represented by the commanding officer) and representatives of the staff bureaus and offices. The staff department officers typically assigned to an army or military department included an assistant adjutant general,

34200-401: Was coined by the French inventor of the semaphore telegraph , Claude Chappe , who also coined the word semaphore . A telegraph is a device for transmitting and receiving messages over long distances, i.e., for telegraphy. The word telegraph alone generally refers to an electrical telegraph . Wireless telegraphy is transmission of messages over radio with telegraphic codes. Contrary to

34400-475: Was composed of numerous organizations, which were generally organized geographically. Each of these armies was usually commanded by a major general . Typically, the Department or District commander also had field command of the army of the same name, but some conflicts within the ranks occurred when this was not true, particularly when an army crossed a geographic boundary. The commanding officer of an army

34600-414: Was demonstrated on the London and Birmingham Railway in July of the same year. In July 1839, a five-needle, five-wire system was installed to provide signalling over a record distance of 21 km on a section of the Great Western Railway between London Paddington station and West Drayton. However, in trying to get railway companies to take up his telegraph more widely for railway signalling , Cooke

34800-421: Was developed in Britain from the 1840s onward. It was used to manage railway traffic and to prevent accidents as part of the railway signalling system. On 12 June 1837 Cooke and Wheatstone were awarded a patent for an electric telegraph. This was demonstrated between Euston railway station —where Wheatstone was located—and the engine house at Camden Town—where Cooke was stationed, together with Robert Stephenson ,

35000-535: Was easily met by patriotic Northerners, abolitionists , and even immigrants who enlisted for a steady income and meals. Over 10,000 German Americans in New York and Pennsylvania immediately responded to Lincoln's call, along with Northern French Americans , who were also quick to volunteer. As more men were needed, however, the number of volunteers fell and both money bounties and forced conscription had to be turned to. Many Southern Unionists would also fight for

35200-452: Was established on March 17, 1862. The board consisted of Ethan A. Hitchcock , the chairman, with Department of War bureau chiefs Lorenzo Thomas (Adjutant General), Montgomery C. Meigs (Quartermaster General), Joseph G. Totten (Chief of Engineers), James W. Ripley (Chief of Ordnance), and Joseph P. Taylor (Commissary General). Reporting directly to the Secretary of War were the bureau chiefs or heads of staff departments which made up

35400-451: Was further differentiation between line officers, who were members of the artillery, cavalry or infantry branches, and staff officers, who were part of the various departments and bureaus of the War Department. All line officers outranked staff officers except in cases pertaining to their staff assignment, in which they received their orders from their respective department chiefs. Regular general officers outranked volunteer general officers of

35600-558: Was given funding to order India silk and cotton cording he had proposed for their construction. Along with that came Lowe's undisclosed recipe for a varnish that would render the balloon envelopes leakproof. The generators were built at the Washington Navy Yard by master joiners who fashioned a contraption of copper plumbing and tanks which, when filled with sulfuric acid and iron filings, would yield hydrogen gas. The generators were Lowe's own design and were considered

35800-605: Was invented by Claude Chappe and operated in France from 1793. The two most extensive systems were Chappe's in France, with branches into neighbouring countries, and the system of Abraham Niclas Edelcrantz in Sweden. During 1790–1795, at the height of the French Revolution , France needed a swift and reliable communication system to thwart the war efforts of its enemies. In 1790, the Chappe brothers set about devising

36000-468: Was invented by US Army surgeon Albert J. Myer in the 1850s who later became the first head of the Signal Corps . Wigwag was used extensively during the American Civil War where it filled a gap left by the electrical telegraph. Although the electrical telegraph had been in use for more than a decade, the network did not yet reach everywhere and portable, ruggedized equipment suitable for military use

36200-646: Was loaded onto a primitive form of an aircraft carrier, the CSS Teaser . Before the first balloon could be used, it was captured by the crew of the USS Maratanza during transportation on the James River. A second balloon was put into action in the summer of 1863, when it was blown from its mooring and taken by Union forces and divided up as souvenirs for members of the Federal Congress. As

36400-782: Was made in 1846, but it took a decade before it was fully taken out of service. The fall of Sevastopol was reported by Chappe telegraph in 1855. The Prussian system was put into effect in the 1830s. However, they were highly dependent on good weather and daylight to work and even then could accommodate only about two words per minute. The last commercial semaphore link ceased operation in Sweden in 1880. As of 1895, France still operated coastal commercial semaphore telegraph stations, for ship-to-shore communication. The early ideas for an electric telegraph included in 1753 using electrostatic deflections of pith balls, proposals for electrochemical bubbles in acid by Campillo in 1804 and von Sömmering in 1809. The first experimental system over

36600-452: Was military leadership a primary consideration in such appointments. Such a policy inevitably resulted in the promotion of inept officers over more able commanders. As the war dragged on and casualties mounted, governors reacted to their constituents' complaints and instead began to issue commissions on the basis of battlefield rather than political competence. Officers tended to suffer a higher percentage of battle wounds on account of either

36800-499: Was not enforced as strictly as in the regular army, and while some NCOs brought with them prior battlefield experience (whether from the Mexican–American War or foreign military service) many at the start of the war were as equally ignorant as their officers in military matters. Training for these NCOs took place during off-duty hours and often involved lessons based on manuals such as Hardee's Tactics . One notable exception

37000-400: Was not immediately available. Permanent or semi-permanent stations were established during the war, some of them towers of enormous height and the system was extensive enough to be described as a communications network. A heliograph is a telegraph that transmits messages by flashing sunlight with a mirror, usually using Morse code. The idea for a telegraph of this type was first proposed as

37200-468: Was offered $ 30 per day for each day his balloon was in use. Lowe offered to accept $ 10 gold per day (colonel's pay) if he were to be allowed to build more suitable balloons. He was also allowed to hire as many men as he needed for $ 3 currency per day. Lowe was able to enlist his father, Clovis Lowe, an accomplished balloonist; Captain Dickinson, a seafaring volunteer from his days of transatlantic attempts;

37400-402: Was offered a major general's commission in the U.S. Army through the letter from Secretary of State William H. Seward to H. S. Sanford , the U.S. Minister at Brussels , July 17, 1861. Colonel Luigi Palma di Cesnola , a former Italian and British soldier and veteran of the Crimean War , commanded the 4th New York Cavalry and would rise to become one of the highest ranking Italian officer in

37600-628: Was over in order to join the Confederate States Army; though few are believed to have done so, their total number is unknown. U.S. President Abraham Lincoln exercised supreme command and control over the army in his capacity as commander-in-chief of the United States Armed Forces . Below him was the Secretary of War , who oversaw the administration of the army, and the general-in-chief , who directed

37800-455: Was preceded by a 50-year history of ingenious but ultimately unsuccessful experiments by inventors to achieve wireless telegraphy by other means. Several wireless electrical signaling schemes based on the (sometimes erroneous) idea that electric currents could be conducted long-range through water, ground, and air were investigated for telegraphy before practical radio systems became available. The original telegraph lines used two wires between

38000-433: Was proposed by Cooke in 1842. Railway signal telegraphy did not change in essence from Cooke's initial concept for more than a century. In this system each line of railway was divided into sections or blocks of varying length. Entry to and exit from the block was to be authorised by electric telegraph and signalled by the line-side semaphore signals, so that only a single train could occupy the rails. In Cooke's original system,

38200-431: Was put: "... not a single Southern Belle was asked to give up her Sunday best for the cause." Eugene Block quotes a letter that Lowe received from Confederate Major General James Longstreet asserting that they were sent out to gather up all the silk dresses to be found to fashion a balloon: While we were longing for balloons that poverty denied us, a genius arose and suggested that we send out and get every silk dress in

38400-501: Was quickly followed by a different system developed in the United States by Samuel Morse . The electric telegraph was slower to develop in France due to the established optical telegraph system, but an electrical telegraph was put into use with a code compatible with the Chappe optical telegraph. The Morse system was adopted as the international standard in 1865, using a modified Morse code developed in Germany in 1848. The heliograph

38600-549: Was rejected several times in favour of the more familiar, but shorter range, steam-powered pneumatic signalling. Even when his telegraph was taken up, it was considered experimental and the company backed out of a plan to finance extending the telegraph line out to Slough . However, this led to a breakthrough for the electric telegraph, as up to this point the Great Western had insisted on exclusive use and refused Cooke permission to open public telegraph offices. Cooke extended

38800-454: Was retained by a tether or series of tethers manned by ground crews. Free flight required that the pilot ascend and return by his own control. Captive flight used ground crews to assist in altitude control and speedy return to the exact starting point. Tethers also allowed for the stringing of telegraph wires back to the ground. Information gathered from balloon observation was relayed to the ground by various means of signaling. From high altitudes

39000-506: Was simply not considered. Eventually though their opponents recognized their existence, and while female spies caught in the act were not typically executed like their male colleagues, they still faced the threat of lengthy prison sentences. For self-evident reasons many of these activities were kept secret and any documentation (if it existed) was often destroyed. As such the identity of many of these women will never be known. Of those who became famous for their espionage work during or after

39200-496: Was still 42.7 percent. During World War I , Britain's telegraph communications were almost completely uninterrupted while it was able to quickly cut Germany's cables worldwide. In 1843, Scottish inventor Alexander Bain invented a device that could be considered the first facsimile machine . He called his invention a "recording telegraph". Bain's telegraph was able to transmit images by electrical wires. Frederick Bakewell made several improvements on Bain's design and demonstrated

39400-404: Was still used, although it was accepted that poor weather ruled it out on many days of the year. France had an extensive optical telegraph system dating from Napoleonic times and was even slower to take up electrical systems. Eventually, electrostatic telegraphs were abandoned in favour of electromagnetic systems. An early experimental system ( Schilling , 1832) led to a proposal to establish

39600-617: Was the Chappe telegraph , an optical telegraph invented by Claude Chappe in the late 18th century. The system was used extensively in France, and European nations occupied by France, during the Napoleonic era . The electric telegraph started to replace the optical telegraph in the mid-19th century. It was first taken up in Britain in the form of the Cooke and Wheatstone telegraph , initially used mostly as an aid to railway signalling . This

39800-480: Was used by British military in many colonial wars, including the Anglo-Zulu War (1879). At some point, a morse key was added to the apparatus to give the operator the same degree of control as in the electric telegraph. Another type of heliograph was the heliostat or heliotrope fitted with a Colomb shutter. The heliostat was essentially a surveying instrument with a fixed mirror and so could not transmit

40000-436: Was working on an attempt to make a transatlantic crossing by balloon. His efforts were interrupted by the onset of the Civil War, which broke out one week before one of his most important test flights. Subsequently, he offered his aviation expertise to the development of an air-war mechanism through the use of aerostats for reconnaissance purposes. Lowe met with U.S. President Abraham Lincoln on 11 June 1861, and proposed
