128-472: After the development of efficient telegraph systems in the 1830s, their use saw almost explosive growth in the 1840s . Samuel Morse 's first experimental line between Washington, D.C. , and Baltimore —the Baltimore-Washington telegraph line —was demonstrated on May 24, 1844. By 1850 there were lines covering most of the eastern states, and a separate network of lines was soon constructed in

256-506: A 175-yard (160 m) long trench as well as an eight-mile (13 km) long overhead telegraph. The lines were connected at both ends to revolving dials marked with the letters of the alphabet and electrical impulses sent along the wire were used to transmit messages. Offering his invention to the Admiralty in July 1816, it was rejected as "wholly unnecessary". His account of the scheme and

384-480: A clock-face, and the signal caused a needle to indicate the letter. This early system required the receiver to be present in real time to record the message and it reached speeds of up to 15 words a minute. In 1846, Alexander Bain patented a chemical telegraph in Edinburgh. The signal current moved an iron pen across a moving paper tape soaked in a mixture of ammonium nitrate and potassium ferrocyanide, decomposing

512-468: A few kilometers (in von Sömmering's design), with each of the telegraph receiver's wires immersed in a separate glass tube of acid. An electric current was sequentially applied by the sender through the various wires representing each letter of a message; at the recipient's end, the currents electrolysed the acid in the tubes in sequence, releasing streams of hydrogen bubbles next to each associated letter or numeral. The telegraph receiver's operator would watch

640-609: A higher rate than poor men because they had more to lose. Slavery helped provide them with wealth and power, and they felt that the Civil War would destroy everything that they had if they lost because they saw slavery as the foundation of their wealth, which was under threat and caused them to fight hard. At many points during the war, and especially near the end, the Confederate armies were very poorly fed. At home their families were in worsening condition and faced starvation and

768-547: A lower grade officer. Barring the same type of circumstances that might leave a lower grade officer in temporary command, divisions were commanded by major generals and corps were commanded by lieutenant generals. A few corps commanders were never confirmed as lieutenant generals and exercised corps command for varying periods as major generals. Armies of more than one corps were commanded by (full) generals. There were four grades of general officer ( general , lieutenant general , major general , and brigadier general ), but all wore

896-583: A month later in May 1865. By the time Abraham Lincoln took office as President of the United States on March 4, 1861, the seven seceding slave states had formed the Confederate States . They seized federal property, including nearly all U.S. Army forts, within their borders. Lincoln was determined to hold the forts remaining under U.S. control when he took office, especially Fort Sumter in

1024-698: A moving paper tape by a stylus which was operated by an electromagnet. Morse and Vail developed the Morse code signalling alphabet . On May 24, 1844, Morse sent to Vail the historic first message “ WHAT HATH GOD WROUGHT " from the Capitol in Washington to the old Mt. Clare Depot in Baltimore . The first commercial electrical telegraph was the Cooke and Wheatstone system . A demonstration four-needle system

1152-576: A permanent magnet and connecting the coil with the transmission wires by means of the commutator. The page of Gauss's laboratory notebook containing both his code and the first message transmitted, as well as a replica of the telegraph made in the 1850s under the instructions of Weber are kept in the faculty of physics at the University of Göttingen , in Germany. Gauss was convinced that this communication would be of help to his kingdom's towns. Later in

1280-426: A practical alphabetical system in 1840 called the A.B.C. System, used mostly on private wires. This consisted of a "communicator" at the sending end and an "indicator" at the receiving end. The communicator consisted of a circular dial with a pointer and the 26 letters of the alphabet (and four punctuation marks) around its circumference. Against each letter was a key that could be pressed. A transmission would begin with

1408-545: A sensitive indicator for an electric current. Also that year, André-Marie Ampère suggested that telegraphy could be achieved by placing small magnets under the ends of a set of wires, one pair of wires for each letter of the alphabet. He was apparently unaware of Schweigger's invention at the time, which would have made his system much more sensitive. In 1825, Peter Barlow tried Ampère's idea but only got it to work over 200 feet (61 m) and declared it impractical. In 1830 William Ritchie improved on Ampère's design by placing

1536-601: A short-distance transmission of signals between two telegraphs in different rooms of his apartment. In 1836, the British government attempted to buy the design but Schilling instead accepted overtures from Nicholas I of Russia . Schilling's telegraph was tested on a 5-kilometre-long (3.1 mi) experimental underground and underwater cable, laid around the building of the main Admiralty in Saint Petersburg and

1664-493: A soldier, and his rejection of a Southern identity as a professional author. Because of the destruction of any central repository of records in the capital at Richmond in 1865 and the comparatively poor record-keeping of the time, there can be no definitive number that represents the strength of the Confederate States Army. Estimates range from 500,000 to 2,000,000 soldiers who were involved at any time during

1792-589: A squad or platoon, the smallest infantry maneuver unit in the Army was a company of 100 soldiers. Ten companies were organized into an infantry regiment, which theoretically had 1,000 men. In reality, as disease, desertions and casualties took their toll, and the common practice of sending replacements to form new regiments took hold, most regiments were greatly reduced in strength. By the mid-war, most regiments averaged 300–400 men, with Confederate units slightly smaller on average than their U.S. counterparts. For example, at

1920-405: A steady rhythm, and the usual speed of operation was 30 words per minute. By this point, reception had been automated, but the speed and accuracy of the transmission were still limited to the skill of the human operator. The first practical automated system was patented by Charles Wheatstone. The message (in Morse code ) was typed onto a piece of perforated tape using a keyboard-like device called

2048-467: A telegraph along the Nuremberg–Fürth railway line , built in 1835 as the first German railroad, which was the first earth-return telegraph put into service. By 1837, William Fothergill Cooke and Charles Wheatstone had co-developed a telegraph system which used a number of needles on a board that could be moved to point to letters of the alphabet. Any number of needles could be used, depending on

2176-492: A terrain that was not always inviting. California Chief Justice Stephen Field sent one of the first messages from San Francisco to Abraham Lincoln , using the occasion to assure the president of California's allegiance to the Union . The construction coincided with Civil War combat to the southeast. The entire cost of the system was half a million dollars (equivalent to $ 17 million in 2023). Difficulties did not stop with

2304-477: A useful communication system. In 1774, Georges-Louis Le Sage realised an early electric telegraph. The telegraph had a separate wire for each of the 26 letters of the alphabet and its range was only between two rooms of his home. In 1800, Alessandro Volta invented the voltaic pile , providing a continuous current of electricity for experimentation. This became a source of a low-voltage current that could be used to produce more distinct effects, and which

2432-481: Is a ready explanation for this apparent paradox. Emancipation was a salient issue for Union soldiers because it was controversial. Slavery was less salient for most Confederate soldiers because it was not controversial. They took slavery for granted as one of the Southern 'rights' and institutions for which they fought, and did not feel compelled to discuss it. Continuing, retired Professor McPherson also stated that of

2560-622: The American Civil War (1861–1865), fighting against the United States forces to win the independence of the Southern states and uphold and expand the institution of slavery . On February 28, 1861, the Provisional Confederate Congress established a provisional volunteer army and gave control over military operations and authority for mustering state forces and volunteers to the newly chosen Confederate States president, Jefferson Davis (1808-1889),. Davis

2688-576: The Army of Tennessee and various other units under General Joseph E. Johnston , surrendered to the U.S. on April 9, 1865 (officially April 12), and April 18, 1865 (officially April 26). Other Confederate forces further south and west surrendered between April 16, 1865, and June 28, 1865. By the end of the war, more than 100,000 Confederate soldiers had deserted , and some estimates put the number as high as one-third of all Confederate soldiers. The Confederacy's government effectively dissolved when it evacuated

2816-590: The Mississippi River . A second significant step was the passing of the Telegraph Act by Congress in 1860, which authorized the government to open bids for the construction of a telegraph line between Missouri and California and regulated the service to be provided. Eventually, the only bidder would be Sibley, because all competitors—Theodore Adams, Benjamin Ficklin and John Harmon—withdrew at

2944-466: The Pony Express obsolete, which officially ceased operations two days later. The overland telegraph line was operated until 1869, when it was replaced by a multi-line telegraph that had been constructed alongside the route of the first transcontinental railroad . Electric telegraph Electrical telegraphy is a point-to-point text messaging system, primarily used from the 1840s until

3072-867: The Potomac River in his first invasion of the North in the Antietam campaign in Maryland in September 1862. The Confederate States Army did not have a formal overall military commander, or general in chief, until late in the war. The Confederate President, Jefferson Davis , himself a former U.S. Army officer and U.S. Secretary of War , served as commander-in-chief and provided the overall strategic direction for Confederate land and naval forces in both eastern and western theaters. The following men had varying degrees of control: The lack of centralized control

3200-471: The United States Army (established 1775 / 1789). It was to consist of a large provisional force to exist only in time of war and a small permanent regular army. The provisional, volunteer army was established by an act of the Provisional Confederate Congress passed on February 28, 1861, one week before the act which established the permanent regular army organization, passed on March 6. Although

3328-546: The booming economy of California. California was admitted to the United States in 1850, the first state on the Pacific coast. Major efforts ensued to integrate California with the other states, including sea, overland mail pioneered by George Chorpenning , the Pony Express , and passenger services such as Butterfield Overland Mail . Proposals for the subsidy of a telegraph line to California were made in Congress throughout

3456-502: The "flimsy and abstract idea that a negro is equal to an Anglo American". One Louisianan artilleryman stated, "I never want to see the day when a negro is put on an equality with a white person. There is too many free niggers ... now to suit me, let alone having four millions." A North Carolinian soldier stated, "[A] white man is better than a nigger." Decades later in 1894 , Virginian and former famous Confederate cavalry leader, John S. Mosby (1833-1916), reflecting on his role in

3584-470: The 'Stick Punch'. The transmitter automatically ran the tape through and transmitted the message at the then exceptionally high speed of 70 words per minute. An early successful teleprinter was invented by Frederick G. Creed . In Glasgow he created his first keyboard perforator, which used compressed air to punch the holes. He also created a reperforator (receiving perforator) and a printer. The reperforator punched incoming Morse signals onto paper tape and

3712-519: The 1850s, and in 1860 the U.S. Post Office was authorized to spend $ 40,000 per year to build and maintain an overland line. The year before, the California State Legislature had authorized a similar subsidy of $ 6,000 per year. Construction of the first transcontinental telegraph was the work of Western Union , which Hiram Sibley , Jeptha Wade , and Ezra Cornell had established in 1856 by merging companies operating east of

3840-928: The American Civil War were volunteers, both sides by 1862 resorted to conscription as a means to supplement the volunteer soldiers. Although exact records are unavailable, estimates of the percentage of Confederate Army soldiers who were drafted are about double the 6 percent of Union Army soldiers who were drafted. According to the National Park Service, "Soldier demographics for the Confederate Army are not available due to incomplete and destroyed enlistment records." Their estimates of Confederate military personnel deaths are about 94,000 killed in battle, 164,000 deaths from disease, and between 25,976 deaths in Union prison camps. One estimate of

3968-494: The American Civil War's soldiers, noted Princeton University war historian and author James M. McPherson (born 1936), contrasts the views of Confederate soldiers regarding slavery with those of the colonial American revolutionaries of the earlier 18th century . He stated that while the American rebel colonists of the 1770s saw an incongruity between owning slaves on the one hand, and proclaiming to be fighting for liberty on

4096-632: The California system. James Gamble , an experienced telegraph builder in California, was put in charge of the western crew, and Edward Creighton was responsible for the eastern crew. From Salt Lake City , a crew in charge of James Street advanced westward, and W.H. Stebbins's crew eastward toward Fort Kearny. Creighton's crew erected its first pole on 4 July 1861. When the project was completed in October 1861, they had planted 27,500 poles holding 2,000 miles (3,200 km) of single-strand iron wire over

4224-594: The Confederacy passed the first conscription law in either Confederate or Union history, the Conscription Act, which made all able bodied white men between the ages of 18 and 35 liable for a three-year term of service in the Provisional Army. It also extended the terms of enlistment for all one-year soldiers to three years. Men employed in certain occupations considered to be most valuable for

4352-821: The Confederacy: Control and operation of the Confederate army were administered by the Confederate States War Department , which was established by the Confederate Provisional Congress in an act on February 21, 1861. The Confederate Congress gave control over military operations, and authority for mustering state forces and volunteers to the President of the Confederate States of America on February 28, 1861, and March 6, 1861. On March 8,

4480-589: The Confederate Congress passed a law that authorized President Davis to issue proclamations to call up no more than 100,000 men. The C.S. War Department asked for 8,000 volunteers on March 9, 20,000 on April 8, and 49,000 on and after April 16. Davis proposed an army of 100,000 soldiers in his message to Congress on April 29. On August 8, 1861, the Confederacy called for 400,000 volunteers to serve for one or three years. Eight months later in April 1862,

4608-558: The Confederate sample. Indeed, while about one-third of all Confederate soldiers belonged to slaveholding families, slightly more than two-thirds of the sample whose slaveholding status is known did so. In some cases, Confederate men were motivated to join the army in response to the United States' actions regarding its opposition to slavery. After the U.S. President Abraham Lincoln issued the Emancipation Proclamation in 1862 - 1863 , some Confederate soldiers welcomed

4736-534: The Episcopalians, Methodists, and Lutherans. One result was wave after wave of religious revivals in the Army, religion playing a major part in the lives of Confederate soldiers. Some men with a weak religious affiliation became committed Christians, and saw their military service in terms of satisfying God's wishes. Religion strengthened the soldiers' loyalty to their comrades and the Confederacy. Military historian Samuel J. Watson argues that Christian faith

4864-579: The ITA-1 Baudot code , a five-bit code. This yielded only thirty-two codes, so it was over-defined into two "shifts", "letters" and "figures". An explicit, unshared shift code prefaced each set of letters and figures. In 1901, Baudot's code was modified by Donald Murray . In the 1930s, teleprinters were produced by Teletype in the US, Creed in Britain and Siemens in Germany. By 1935, message routing

4992-591: The Imperial palace at Tsarskoye Selo and Kronstadt Naval Base . In 1833, Carl Friedrich Gauss , together with the physics professor Wilhelm Weber in Göttingen , installed a 1,200-metre-long (3,900 ft) wire above the town's roofs. Gauss combined the Poggendorff-Schweigger multiplicator with his magnetometer to build a more sensitive device, the galvanometer . To change the direction of

5120-459: The Morse system became the standard for international communication, using a modified form of Morse's code that had been developed for German railways. Electrical telegraphs were used by the emerging railway companies to provide signals for train control systems, minimizing the chances of trains colliding with each other. This was built around the signalling block system in which signal boxes along

5248-519: The Morse system. As well as the rapid expansion of the use of the telegraphs along the railways, they soon spread into the field of mass communication with the instruments being installed in post offices . The era of mass personal communication had begun. Telegraph networks were expensive to build, but financing was readily available, especially from London bankers. By 1852, National systems were in operation in major countries: The New York and Mississippi Valley Printing Telegraph Company, for example,

5376-407: The Union. They felt that they had no choice but to help defend their homes. President Abraham Lincoln was exasperated to hear of such men who professed to love their country but were willing to fight against it. As in the U.S. Army , the Confederate Army's soldiers were organized by military specialty. The combat arms included infantry, cavalry, and artillery. Although fewer soldiers might comprise

5504-582: The alphabet, a message could be transmitted by connecting the wire terminals in turn to an electrostatic machine, and observing the deflection of pith balls at the far end. The writer has never been positively identified, but the letter was signed C.M. and posted from Renfrew leading to a Charles Marshall of Renfrew being suggested. Telegraphs employing electrostatic attraction were the basis of early experiments in electrical telegraphy in Europe, but were abandoned as being impractical and were never developed into

5632-546: The application of electricity to communications at a distance. All the known effects of electricity – such as sparks , electrostatic attraction , chemical changes , electric shocks , and later electromagnetism  – were applied to the problems of detecting controlled transmissions of electricity at various distances. In 1753, an anonymous writer in the Scots Magazine suggested an electrostatic telegraph. Using one wire for each letter of

5760-553: The armature was intended to make marks on paper tape, but operators learned to interpret the clicks and it was more efficient to write down the message directly. In 1851, a conference in Vienna of countries in the German-Austrian Telegraph Union (which included many central European countries) adopted the Morse telegraph as the system for international communications. The international Morse code adopted

5888-474: The army, such as the construction of fortifications and defenses or driving wagons. Since these figures include estimates of the total number of soldiers who served at any time during the war, they do not represent the size of the army at any given date. These numbers also do not include sailors / marines who served in the Confederate States Navy . Although most of the soldiers who fought in

6016-420: The bar, creating a much more powerful electromagnet which could operate a telegraph through the high resistance of long telegraph wires. During his tenure at The Albany Academy from 1826 to 1832, Henry first demonstrated the theory of the 'magnetic telegraph' by ringing a bell through one-mile (1.6 km) of wire strung around the room in 1831. In 1835, Joseph Henry and Edward Davy independently invented

6144-403: The bubbles and could then record the transmitted message. This is in contrast to later telegraphs that used a single wire (with ground return). Hans Christian Ørsted discovered in 1820 that an electric current produces a magnetic field that will deflect a compass needle. In the same year Johann Schweigger invented the galvanometer , with a coil of wire around a compass, that could be used as

6272-697: The chemical and producing readable blue marks in Morse code. The speed of the printing telegraph was 16 and a half words per minute, but messages still required translation into English by live copyists. Chemical telegraphy came to an end in the US in 1851, when the Morse group defeated the Bain patent in the US District Court. For a brief period, starting with the New York–Boston line in 1848, some telegraph networks began to employ sound operators, who were trained to understand Morse code aurally. Gradually,

6400-454: The city harbor began bombarding bombarding Fort Sumter on April 12–13, 1861 and forced its capitulation on April 14. The remaining loyal United States in the North, outraged by the Confederacy's attack, demanded war. It rallied behind new 16th President Lincoln's call on April 15 for all the loyal states to send their state militia units avolunteer troops to reinforce and protect the national federal capital of Washington, D.C. , to recapture

6528-447: The communicator. Pressing another key would then release the pointer and the previous key, and re-connect the magneto to the line. These machines were very robust and simple to operate, and they stayed in use in Britain until well into the 20th century. The Morse system uses a single wire between offices. At the sending station, an operator taps on a switch called a telegraph key , spelling out text messages in Morse code . Originally,

6656-418: The completion of the project. Keeping it in operation faced multiple problems: (a) inclement weather in the form of lightning bolts, strong winds, and heavy snow damaged both poles and the wire; (b) rubbing on the poles by bison from time to time sent down sections of the telegraph, eventually contributing to their demise; (c) the system had to be rerouted through Chicago to avoid Confederate attempts to cut

6784-559: The depredations of roving bands of marauders. Many soldiers went home temporarily (A.W.O.L. - " Absent Without Official Leave ") and quietly returned when their family problems had been resolved. By September 1864, however, President Davis publicly admitted that two-thirds of the soldiers were absent, "most of them without leave". The problem escalated rapidly after that, and fewer and fewer men returned. Soldiers who were fighting in defense of their homes realized that they had to desert to fulfill that duty. Historian Mark Weitz argues that

6912-531: The east coast by 24 October 1861, bringing an end to the Pony Express . France was slow to adopt the electrical telegraph, because of the extensive optical telegraph system built during the Napoleonic era . There was also serious concern that an electrical telegraph could be quickly put out of action by enemy saboteurs, something that was much more difficult to do with optical telegraphs which had no exposed hardware between stations. The Foy-Breguet telegraph

7040-504: The electric current, he constructed a commutator of his own. As a result, he was able to make the distant needle move in the direction set by the commutator on the other end of the line. At first, Gauss and Weber used the telegraph to coordinate time, but soon they developed other signals and finally, their own alphabet. The alphabet was encoded in a binary code that was transmitted by positive or negative voltage pulses which were generated by means of moving an induction coil up and down over

7168-605: The electric telegraph, visual systems were used, including beacons , smoke signals , flag semaphore , and optical telegraphs for visual signals to communicate over distances of land. An auditory predecessor was West African talking drums . In the 19th century, Yoruba drummers used talking drums to mimic human tonal language to communicate complex messages – usually regarding news of birth, ceremonies, and military conflict – over 4–5 mile distances. From early studies of electricity , electrical phenomena were known to travel with great speed, and many experimenters worked on

7296-458: The extent the word " battalion " was used to describe a military unit, it referred to a multi-company task force of a regiment or a near-regimental size unit. Throughout the war, the Confederacy raised the equivalent of 1,010 regiments in all branches, including militias, versus 2,050 regiments for the U.S. Army. Four regiments usually formed a brigade , although as the number of soldiers in many regiments became greatly reduced, especially later in

7424-521: The first means of radiowave telecommunication, which he began in 1894. In the early 20th century, manual operation of telegraph machines was slowly replaced by teleprinter networks. Increasing use of the telephone pushed telegraphy into only a few specialist uses; its use by the general public dwindled to greetings for special occasions. The rise of the Internet and email in the 1990s largely made dedicated telegraphy networks obsolete. Prior to

They were eventually caught and captured near Irwinville, Georgia

7680-422: The harbor of Charleston, South Carolina . On February 28, shortly before Lincoln was sworn in as president, the Provisional Confederate Congress had authorized the organization of a large Provisional Army of the Confederate States (PACS). Under orders from Confederate President Jefferson Davis , C.S. troops under the command of General Pierre Gustave Toutant / P. G. T. Beauregard military forces surrounding

7808-407: The heritage of 1776 in opposite ways. Confederates professed to fight for liberty and independence from a too radical government; Unionists said they fought to preserve the nation conceived in liberty from dismemberment and destruction ... The rhetoric of liberty that had permeated the letters of Confederate volunteers in 1861, grew even stronger as the war progressed. Before and during the Civil War,

SECTION 60

7936-618: The home front (such as railroad and river workers, civil officials, telegraph operators, miners, druggists and teachers) were exempt from the draft. The act was amended twice in 1862. On September 27, the maximum age of conscription was extended to 45. On October 11, the Confederate States Congress passed the so-called " Twenty Negro Law ", which exempted anyone who owned 20 or more slaves, a move that caused deep resentment among conscripts who did not own slaves. The C.S. Congress enacted several more amendments throughout

8064-446: The hundreds of Confederate soldiers' letters he had examined, none of them contained any anti-slavery sentiment whatsoever: Although only 20 percent of the soldiers avowed explicit proslavery purposes in their letters and diaries, none at all dissented from that view. McPherson admits some flaws in his sampling of letters. Soldiers from slaveholding families were overrepresented by 100%: Nonslaveholding farmers are underrepresented in

8192-661: The last minute. Later they joined Sibley in his effort. Similar to the first transcontinental railroad , elimination of the gap in the telegraph service between Fort Kearny in Nebraska and Fort Churchill in Nevada was planned to be divided between teams that would be advancing the construction in opposite directions. The Pacific Telegraph Company would build west from Nebraska and the Overland Telegraph Company would build east from Nevada's connection to

8320-615: The late 20th century. It was the first electrical telecommunications system and the most widely used of a number of early messaging systems called telegraphs , that were devised to send text messages more quickly than physically carrying them. Electrical telegraphy can be considered the first example of electrical engineering . Text telegraphy consisted of two or more geographically separated stations, called telegraph offices . The offices were connected by wires, usually supported overhead on utility poles . Many electrical telegraph systems were invented that operated in different ways, but

8448-453: The line communicate with neighbouring boxes by telegraphic sounding of single-stroke bells and three-position needle telegraph instruments. In the 1840s, the electrical telegraph superseded optical telegraph systems such as semaphores, becoming the standard way to send urgent messages. By the latter half of the century, most developed nations had commercial telegraph networks with local telegraph offices in most cities and towns, allowing

8576-584: The line in Missouri to disrupt communications among Union forces; (d) Native Americans soon started to do the same farther west as part of their hostilities with the Army. Financially, the first transcontinental telegraph was a big success from the beginning. The charge during the first week of operation was US$ 1 (equivalent to about $ 34 in 2023) per word, whereas the Telegraph Act of 1860 had specified 30 cents. The telegraph line immediately made

8704-491: The magnetic needles inside a coil of wire connected to each pair of conductors. He successfully demonstrated it, showing the feasibility of the electromagnetic telegraph, but only within a lecture hall. In 1825, William Sturgeon invented the electromagnet , with a single winding of uninsulated wire on a piece of varnished iron , which increased the magnetic force produced by electric current. Joseph Henry improved it in 1828 by placing several windings of insulated wire around

8832-477: The mercury dipping electrical relay , in which a magnetic needle is dipped into a pot of mercury when an electric current passes through the surrounding coil. In 1837, Davy invented the much more practical metallic make-and-break relay which became the relay of choice in telegraph systems and a key component for periodically renewing weak signals. Davy demonstrated his telegraph system in Regent's Park in 1837 and

8960-602: The military situation at Charleston Harbor in Charleston, South Carolina , where South Carolina state militia had besieged the longtime Federal Fort Sumter in Charleston harbor, held by a small U.S. Army garrison under the command of Major Robert Anderson . (1805-1871). By March 1861, the Provisional Congress of the Confederate States meeting in the temporary capital of Montgomery, Alabama , expanded

9088-432: The most widely used of its type was the Cooke and Wheatstone telegraph , invented in 1837. The second category are armature systems, in which the current activates a telegraph sounder that makes a click; communication on this type of system relies on sending clicks in coded rhythmic patterns. The archetype of this category was the Morse system and the code associated with it, both invented by Samuel Morse in 1838. In 1865,

9216-511: The move, as they believed it would strengthen pro-slavery sentiment in the Confederacy, and thus lead to greater enlistment of soldiers in the Confederate armies. One Confederate soldier from the West in Texas gave his reasons for fighting for the Confederacy, stating that "we are fighting for our property", contrasting this with the motivations of Union soldiers, who, he claimed, were fighting for

9344-592: The need to protect or to destroy slavery. Others point to less overtly political reasons to fight, such as the defense of one's home and family, or the honor and brotherhood to be preserved when fighting alongside other men. Most historians agree that, no matter what he thought about when he went into the war, the experience of combat affected him profoundly and sometimes affected his reasons for continuing to fight. Educated soldiers drew upon their knowledge of American history to justify their costs. Historian James M. McPherson says: Confederate and Union soldiers interpreted

9472-422: The number of characters it was required to code. In May 1837 they patented their system. The patent recommended five needles, which coded twenty of the alphabet's 26 letters. Samuel Morse independently developed and patented a recording electric telegraph in 1837. Morse's assistant Alfred Vail developed an instrument that was called the register for recording the received messages. It embossed dots and dashes on

9600-464: The official count of 103,400 deserters is too low. He concludes that most of the desertions came because the soldier felt he owed a higher duty to his own family than to the Confederacy. Confederate policies regarding desertion generally were severe. For example, on August 19, 1862, famed General Thomas J. "Stonewall" Jackson (1824-1863), approved the court-martial sentence of execution for three soldiers for desertion, rejecting pleas for clemency from

9728-414: The ones that became widespread fit into two broad categories. First are the needle telegraphs, in which electric current sent down the telegraph line produces electromagnetic force to move a needle-shaped pointer into position over a printed list. Early needle telegraph models used multiple needles, thus requiring multiple wires to be installed between stations. The first commercial needle telegraph system and

9856-464: The other, the later Confederacy's soldiers did not, as the Confederate ideology of white supremacy negated any contradiction between the two: Unlike many slaveholders in the age of Thomas Jefferson, Confederate soldiers from slaveholding families expressed no feelings of embarrassment or inconsistency in fighting for their liberty while holding other people in slavery. Indeed, white supremacy and

9984-451: The pivotal Battle of Chancellorsville , the average U.S. Army infantry regiment's strength was 433 men, versus 409 for Confederate infantry regiments. Rough unit sizes for CSA combat units during the war: Regiments, which were the basic units of army organization through which soldiers were supplied and deployed, were raised by individual states. They were generally referred by number and state, for example 1st Texas , 12th Virginia . To

10112-415: The pointer reached the position of the depressed key, it would stop and the magneto would be disconnected from the line. The communicator's pointer was geared to the magneto mechanism. The indicator's pointer was moved by a polarised electromagnet whose armature was coupled to it through an escapement . Thus the alternating line voltage moved the indicator's pointer on to the position of the depressed key on

10240-410: The pointers on the dials at both ends set to the start position. The transmitting operator would then press down the key corresponding to the letter to be transmitted. In the base of the communicator was a magneto actuated by a handle on the front. This would be turned to apply an alternating voltage to the line. Each half cycle of the current would advance the pointers at both ends by one position. When

10368-469: The popular press of Richmond, including its five major newspapers, sought to inspire a sense of patriotism, Confederate identity, and the moral high ground in the southern population. The southern churches met the shortage of Army chaplains by sending missionaries. The Southern Baptists sent a total of 78 missionaries, starting in 1862. Presbyterians were even more active, with 112 missionaries sent in early 1865. Other missionaries were funded and supported by

10496-513: The possibilities of rapid global communication in Descriptions of an Electrical Telegraph and of some other Electrical Apparatus was the first published work on electric telegraphy and even described the risk of signal retardation due to induction. Elements of Ronalds' design were utilised in the subsequent commercialisation of the telegraph over 20 years later. The Schilling telegraph , invented by Baron Schilling von Canstatt in 1832,

10624-580: The printer decoded this tape to produce alphanumeric characters on plain paper. This was the origin of the Creed High Speed Automatic Printing System, which could run at an unprecedented 200 words per minute. His system was adopted by the Daily Mail for daily transmission of the newspaper contents. With the invention of the teletypewriter , telegraphic encoding became fully automated. Early teletypewriters used

10752-613: The provisional military forces and established a more permanent regular Confederate States Army. An accurate count of the total number of individuals who served in the Military forces of the Confederate States (Army, Navy and Marine Corps) is not possible due to incomplete and destroyed / burned Confederate records; and archives. Estimates of the number of Confederate soldiers, sailors and marines are between 750,000 and 1,000,000 troops. This does not include an unknown number of Negro slaves who were pressed into performing various tasks for

10880-497: The public to send messages (called telegrams ) addressed to any person in the country, for a fee. Beginning in 1850, submarine telegraph cables allowed for the first rapid communication between people on different continents. The telegraph's nearly-instant transmission of messages across continents – and between continents – had widespread social and economic impacts. The electric telegraph led to Guglielmo Marconi 's invention of wireless telegraphy ,

11008-404: The rank of (full) general; the highest-ranking (earliest date of rank) was Samuel Cooper , Adjutant General and Inspector General of the Confederate States Army. Officers' uniforms bore a braided design on the sleeves and kepi , the number of adjacent strips (and therefore the width of the lines of the design) denoting rank. The color of the piping and kepi denoted the military branch. The braid

11136-480: The receiving end. The system was very stable and accurate and became accepted around the world. The next improvement was the Baudot code of 1874. French engineer Émile Baudot patented a printing telegraph in which the signals were translated automatically into typographic characters. Each character was assigned a five-bit code, mechanically interpreted from the state of five on/off switches. Operators had to maintain

11264-450: The return current and one for a signal bell. When at the starting station the operator pressed a key, the corresponding pointer was deflected at the receiving station. Different positions of black and white flags on different disks gave combinations which corresponded to the letters or numbers. Pavel Schilling subsequently improved its apparatus by reducing the number of connecting wires from eight to two. On 21 October 1832, Schilling managed

11392-443: The right of property in slaves were at the core of the ideology for which Confederate soldiers fought. McPherson states that Confederate States Army soldiers did not discuss the issue of slavery as often as the opposing United States Army soldiers did, because most Confederate soldiers readily accepted as an obvious fact that they were fighting to perpetuate slavery and thus did not feel the need to debate over it: [O]nly 20 percent of

11520-409: The same insignia regardless of grade. This was a decision made early in the conflict. The Confederate Congress initially made the rank of brigadier general the highest rank. As the war progressed, the other general-officer ranks were quickly added, but no insignia for them was created. (Robert E. Lee was a notable exception to this. He chose to wear the rank insignia of a colonel.) Only seven men achieved

11648-473: The same year, instead of a voltaic pile , Gauss used an induction pulse, enabling him to transmit seven letters a minute instead of two. The inventors and university did not have the funds to develop the telegraph on their own, but they received funding from Alexander von Humboldt . Carl August Steinheil in Munich was able to build a telegraph network within the city in 1835–1836. In 1838, Steinheil installed

11776-422: The sample of 429 Southern soldiers explicitly voiced proslavery convictions in their letters or diaries. As one might expect, a much higher percentage of soldiers from slaveholding families than from non-slaveholding families expressed such a purpose: 33 percent, compared with 12 percent. Ironically, the proportion of Union soldiers who wrote about the slavery question was greater, as the next chapter will show. There

11904-426: The sending rate. There were many experiments with moving pointers, and various electrical encodings. However, most systems were too complicated and unreliable. A successful expedient to reduce the cost per message was the development of telegraphese . The first system that did not require skilled technicians to operate was Charles Wheatstone's ABC system in 1840 in which the letters of the alphabet were arranged around

12032-459: The soldiers' regimental commander. General Jackson's goal was to maintain discipline in a volunteer army whose homes were under threat of enemy occupation. Historians of the Civil War have emphasized how soldiers from poor families deserted because they were urgently needed at home. Local pressures mounted as Union forces occupied more and more Confederate territory, putting more and more families at risk of hardship. One Confederate Army officer at

12160-488: The solidarity of the Confederacy was dissatisfaction in the Appalachian Mountains districts caused by lingering Unionism and a distrust of the power wielded by the slave-holding class. Many of their soldiers deserted, returned home, and formed a military force that fought off Regular Army units trying to capture and punish them. North Carolina lost nearly a quarter of its soldiers (24,122) to desertion. This

12288-509: The state capital of Virginia in Richmond. Both the United States and the Confederate States began in earnest to raise large, mostly volunteer, armies, with the opposing objectives: putting down the rebellion and preserving the Union on the one hand, and establishing Southern independence from the northern United States on the other. The Confederate States Congress provided for a regular Confederate States Army, patterned after its parent in

12416-455: The subsequent acts came before five state supreme courts; all five upheld them. In his 2010 book Major Problems in the Civil War , historian Michael Perman says that historians are of two minds on why millions of men seemed so eager to fight, suffer and die over four years: Some historians emphasize that Civil War soldiers were driven by political ideology, holding firm beliefs about the importance of liberty, Union, or state rights, or about

12544-456: The time noted, "The deserters belong almost entirely to the poorest class of non-slave-holders whose labor is indispensable to the daily support of their families" and that "When the father, husband or son is forced into the service, the suffering at home with them is inevitable. It is not in the nature of these men to remain quiet in the ranks under such circumstances." Some soldiers also deserted from ideological motivations. A growing threat to

12672-401: The total Confederate wounded is 194,026. In comparison, the best estimates of the number of Union military personnel deaths are 110,100 killed in battle, 224,580 deaths from disease, and 30,218 deaths in Confederate prison camps. The estimated figure for Union Army wounded is 275,174. The main Confederate armies, the Army of Northern Virginia under General Robert E. Lee and the remnants of

12800-433: The two clicks. The message was then written out in long-hand. Royal Earl House developed and patented a letter-printing telegraph system in 1846 which employed an alphabetic keyboard for the transmitter and automatically printed the letters on paper at the receiver, and followed this up with a steam-powered version in 1852. Advocates of printing telegraphy said it would eliminate Morse operators' errors. The House machine

12928-400: The two forces were to exist concurrently, little was done to organize the Confederate regular army. Members of all the military forces of the Confederate States (the army, the navy, and the marine corps) are often referred to as "Confederates", and members of the Confederate army were referred to as "Confederate soldiers". Supplementing the Confederate army were the various state militias of

13056-416: The use of sound operators eliminated the need for telegraph receivers to include register and tape. Instead, the receiving instrument was developed into a "sounder", an electromagnet that was energized by a current and attracted a small iron lever. When the sounding key was opened or closed, the sounder lever struck an anvil. The Morse operator distinguished a dot and a dash by the short or long interval between

13184-443: The various forts, arsenals, shipyards and other seized federal installations from the secessionists, to put down and suppress the rebellion and to save the Union. Four more upper border slave states (North Carolina, Tennessee, Arkansas and finally Virginia) then joined the Confederacy, making eleven seceded states rather than fight fellow Southerners. The Confederacy then moved its national capital from temporary Montgomery, Alabama to

13312-436: The war to address losses suffered in battle as well as the United States' greater supply of manpower. In December 1863, it abolished the previous practice of allowing a rich drafted man to hire a substitute to take his place in the ranks. Substitution had also been practiced in the United States, leading to similar resentment from the lower classes. In February 1864, the age limits were extended to between 17 and 50. Challenges to

13440-488: The war, more than four were often assigned to a brigade. Occasionally, regiments would be transferred between brigades. Two to four brigades usually formed a division . Two to four divisions usually formed a corps . Two to four corps usually formed an army. Occasionally, a single corps might operate independently as if it were a small army. The Confederate States Army consisted of several field armies, named after their primary area of operation. The largest Confederate field army

13568-590: The war, stated in a letter to a friend that "I've always understood that we went to war on account of the thing we quarreled with the North about. I've never heard of any other cause than slavery." As stated by researcher / authors Andrew Hall, Connor Huff and Shiro Kuriwaki in the article Wealth, Slaveownership, and Fighting for the Confederacy: An Empirical Study of the American Civil War , research done using an 1862 Georgia lottery showed that rich white Southern men actually enlisted at

13696-486: The war. Reports from the C.S. War Department beginning at the end of 1861 indicated 326,768 men that year, 449,439 in 1862, 464,646 in 1863, 400,787 in 1864, and "last reports" showed 358,692. Estimates of enlistments throughout the war range from 1,227,890 to 1,406,180. The following calls for soldiers were issued: The C.S.A. was initially a (strategically) defensive army, and many soldiers were resentful when General Robert E. Lee led his Army of Northern Virginia across

13824-410: Was a five-needle, six-wire system, and had the major advantage of displaying the letter being sent so operators did not need to learn a code. The insulation failed on the underground cables between Paddington and West Drayton, and when the line was extended to Slough in 1843, the system was converted to a one-needle, two-wire configuration with uninsulated wires on poles. The cost of installing wires

13952-680: Was a graduate of the United States Military Academy , on the Hudson River at West Point, New York , colonel of a volunteer regiment during the Mexican–American War (1846-1848). He had also been a United States senator from Mississippi and served as U.S. Secretary of War under 14th President Franklin Pierce . On March 1, 1861, on behalf of the new Confederate States government, Davis assumed control of

14080-410: Was a major factor in combat motivation. According to his analysis, the soldiers' faith was consoling for the loss of comrades; it was a shield against fear; it helped reduce drinking and fighting in the ranks; it enlarged the soldiers' community of close friends and helped compensate for their long-term separation from home. In his 1997 book For Cause and Comrades , which examines the motivations of

14208-449: Was a strategic weakness for the Confederacy, and there are only a few examples of its armies acting in concert across multiple theaters to achieve a common objective. One instance occurred in late 1862 with Lee's invasion of Maryland , coincident with two other actions: Bragg's invasion of Kentucky and Earl Van Dorn 's advance against Corinth, Mississippi . All three initiatives were unsuccessful, however. Georgia Governor Joseph E. Brown

14336-415: Was an early needle telegraph . It had a transmitting device that consisted of a keyboard with 16 black-and-white keys. These served for switching the electric current. The receiving instrument consisted of six galvanometers with magnetic needles, suspended from silk threads . The two stations of Schilling's telegraph were connected by eight wires; six were connected with the galvanometers, one served for

14464-845: Was an extreme case of a Southern States Rights advocate asserting control over Confederate soldiers: he defied the Confederate government's wartime policies and resisted the military draft. Believing that local troops should be used only for the defense of Georgia, Brown tried to stop Colonel Francis Bartow from taking Georgia troops out of the state to the First Battle of Bull Run. Many of the Confederacy's senior military leaders (including Robert E. Lee, Albert Sidney Johnston , and James Longstreet ) and even President Jefferson Davis, were former U.S. Army and, in smaller numbers, U.S. Navy officers who had been opposed to, disapproved of, or were at least unenthusiastic about secession, but resigned their U.S. commissions upon hearing that their states had left

14592-435: Was approved for a telegraph between the imperial palace at Peterhof and the naval base at Kronstadt . However, the project was cancelled following Schilling's death in 1837. Schilling was also one of the first to put into practice the idea of the binary system of signal transmission. His work was taken over and developed by Moritz von Jacobi who invented telegraph equipment that was used by Tsar Alexander III to connect

14720-533: Was considerably modified from the original American Morse code , and was based on a code used on Hamburg railways ( Gerke , 1848). A common code was a necessary step to allow direct telegraph connection between countries. With different codes, additional operators were required to translate and retransmit the message. In 1865, a conference in Paris adopted Gerke's code as the International Morse code and

14848-658: Was created in 1852 in Rochester, New York and eventually became the Western Union Telegraph Company . Although many countries had telegraph networks, there was no worldwide interconnection. Message by post was still the primary means of communication to countries outside Europe. Telegraphy was introduced in Central Asia during the 1870s. A continuing goal in telegraphy was to reduce the cost per message by reducing hand-work, or increasing

14976-523: Was eventually adopted. This was a two-needle system using two signal wires but displayed in a uniquely different way to other needle telegraphs. The needles made symbols similar to the Chappe optical system symbols, making it more familiar to the telegraph operators. The optical system was decommissioned starting in 1846, but not completely until 1855. In that year the Foy-Breguet system was replaced with

15104-669: Was far less limited than the momentary discharge of an electrostatic machine , which with Leyden jars were the only previously known human-made sources of electricity. Another very early experiment in electrical telegraphy was an "electrochemical telegraph" created by the German physician , anatomist and inventor Samuel Thomas von Sömmering in 1809, based on an earlier 1804 design by Spanish polymath and scientist Francisco Salva Campillo . Both their designs employed multiple wires (up to 35) to represent almost all Latin letters and numerals. Thus, messages could be conveyed electrically up to

15232-484: Was granted a patent on 4 July 1838. Davy also invented a printing telegraph which used the electric current from the telegraph signal to mark a ribbon of calico infused with potassium iodide and calcium hypochlorite . The first working telegraph was built by the English inventor Francis Ronalds in 1816 and used static electricity. At the family home on Hammersmith Mall , he set up a complete subterranean system in

15360-459: Was henceforth the international standard. The US, however, continued to use American Morse code internally for some time, hence international messages required retransmission in both directions. In the United States, the Morse/Vail telegraph was quickly deployed in the two decades following the first demonstration in 1844. The overland telegraph connected the west coast of the continent to

15488-427: Was implemented in Germany during the 1930s as a network used to communicate within the government. At the rate of 45.45 (±0.5%) baud – considered speedy at the time – up to 25 telex channels could share a single long-distance telephone channel by using voice frequency telegraphy multiplexing , making telex the least expensive method of reliable long-distance communication. Automatic teleprinter exchange service

15616-539: Was installed on the Euston to Camden Town section of Robert Stephenson 's London and Birmingham Railway in 1837 for signalling rope-hauling of locomotives. It was rejected in favour of pneumatic whistles. Cooke and Wheatstone had their first commercial success with a system installed on the Great Western Railway over the 13 miles (21 km) from Paddington station to West Drayton in 1838. This

15744-597: Was introduced into Canada by CPR Telegraphs and CN Telegraph in July 1957 and in 1958, Western Union started to build a Telex network in the United States. Confederate States Army The Confederate States Army , also called the Confederate Army or the Southern Army , was the military land force of the Confederate States of America (commonly referred to as the Confederacy) during

15872-509: Was the Army of Northern Virginia , whose surrender at Appomattox Courthouse in 1865 marked the end of major combat operations in the U.S. Civil War. Companies were commanded by captains and had two or more lieutenants. Regiments were commanded by colonels. Lieutenant colonels were second in command. At least one major was next in command. Brigades were commanded by brigadier generals although casualties or other attrition sometimes meant that brigades would be commanded by senior colonels or even

16000-439: Was the highest rate of desertion of any Confederate state. Young Samuel Clemens (1835-1910, later to be known as Mark Twain ) soon deserted the Southern army long before he became a world-famous writer, journalist and lecturer, but he often commented upon that episode in his life comically, even writing a book about it. Author Neil Schmitz has examined the deep unease Twain felt about losing his honor, his fear of facing death as

16128-469: Was the last great barrier to full automation. Large telegraphy providers began to develop systems that used telephone-like rotary dialling to connect teletypewriters. These resulting systems were called "Telex" (TELegraph EXchange). Telex machines first performed rotary-telephone-style pulse dialling for circuit switching , and then sent data by ITA2 . This "type A" Telex routing functionally automated message routing. The first wide-coverage Telex network

16256-426: Was ultimately more economically significant than the cost of training operators. The one-needle telegraph proved highly successful on British railways, and 15,000 sets were in use at the end of the nineteenth century; some remained in service in the 1930s. The Electric Telegraph Company , the world's first public telegraphy company, was formed in 1845 by financier John Lewis Ricardo and Cooke. Wheatstone developed

16384-477: Was used on four main American telegraph lines by 1852. The speed of the House machine was announced as 2600 words an hour. David Edward Hughes invented the printing telegraph in 1855; it used a keyboard of 26 keys for the alphabet and a spinning type wheel that determined the letter being transmitted by the length of time that had elapsed since the previous transmission. The system allowed for automatic recording on
