203-635: Other engagements Associated articles 1915 1916 1917 1918 Associated articles The Nivelle offensive (16 April – 9 May 1917) was a Franco-British operation on the Western Front in the First World War which was named after General Robert Nivelle , the commander-in-chief of the French metropolitan armies, who led the offensive. The French part of the offensive was intended to be strategically decisive by breaking through
406-475: A 2 mi (3.2 km) front. Preceded by a hurricane bombardment lasting only 35 minutes, the village was captured within four hours. The advance then slowed because of supply and communication difficulties. The Germans brought up reserves and counterattacked , forestalling the attempt to capture the ridge. Since the British had used about a third of their artillery ammunition , General Sir John French blamed
609-401: A Chasseur battalion of the 127th Division and a regiment of the 18th Division. Two days later a battalion of the 166th Division staged a demonstration and on 20 May, the 128th Regiment of the 3rd Division and the 66th Regiment of the 18th Division refused orders; individual incidents of insubordination occurred in the 17th Division. Over the next two days spokesmen were elected in two regiments of
812-584: A French attack by the 164th Division, supported by flame-throwers, captured the 70 ft (21 m)-deep Dragon's Cave shelter at Hurtebise and adjacent positions, from which they repulsed a German counter-attack at the end of June. The capture of the Dragon's Cave marked the beginning of the Battle of the Observatories proper, which lasted all summer as both sides fought for possession of the high ground on
1015-635: A French attack on 4 and 5 May by two regiments captured Craonne and took the edge of the Californie plateau but was not able to cross the Ailette River. An attack by the Tenth Army took Vauclair and the I Colonial Corps took the ruins of Laffaux Mill, before operations were suspended again on 8 May. The Germans began a counter-offensive from Vauxaillon at the west end of the Chemin des Dames, to
1218-481: A German counter-attack on 19 April by the 5th and 6th ( Eingreif divisions,) the 23rd Division and one regiment between Nauroy and Moronvilliers. On the west bank, the Moroccan Division was repulsed on the right and captured Mont sans Nom on the left. To the north-east of the hill the advance reached a depth of 2.4 km (1.5 mi) and next day the advance was pressed beyond Mont Haut and Mont Cornet
1421-519: A German defence which recovered from the defeats of 9 April and organised reverse-slope defences, which were much easier to hold. By 16 May the British had made significant advances and captured 254 German guns but had been unable to achieve a breakthrough. New tactics had been used, particularly in the first phase and had demonstrated that set-piece assaults against elaborately fortified positions could be successful. The Fifth Army attacked on 16 April at 6:00 a.m., which dawned misty and overcast. From
1624-475: A German message ordering the front garrisons to be ready at 5:30 a.m. and changed zero hour to 5:15 a.m. It began to rain at 6:00 a.m. and a force of 63 Schneider CA1 and Saint-Chamond tanks many bogged down in mud. The French infantry and 21 tanks reached the German second position according to plan; the 38th Division captured Fort de Malmaison and XXI Corps took Allemant and Vaudesson. On 25 October
1827-418: A belief among the rank and file that their sacrifices were not appreciated by their government or senior officers. Combatants on both sides claimed the battle was the most psychologically exhausting of the war; recognising this, Pétain frequently rotated divisions, in a process known as the noria system. While this ensured units were withdrawn before their ability to fight was significantly eroded, it meant that
2030-476: A breakthrough from a counter-offensive. He also kept tight control of the main reserve, feeding in just enough troops to keep the battle going. In preparation for their attack, the Germans had amassed a concentration of aircraft near the fortress. In the opening phase, they swept the air space of French aircraft, which allowed German artillery-observation aircraft and bombers to operate without interference. In May,
2233-439: A breakthrough might no longer be possible and instead focused on forcing a French defeat by inflicting massive casualties. His new goal was to "bleed France white." As such, he adopted two new strategies. The first was the use of unrestricted submarine warfare to cut off entente supplies arriving from overseas. The second would be attacks against the French army intended to inflict maximum casualties; Falkenhayn planned to attack

#17327654640822436-537: A brief engagement first on 7 August, and then again on 23 August, but German reserve forces engaged them in the Battle of Mulhouse and forced the French to retreat twice. The German Army swept through Belgium, executing civilians and razing villages. The application of "collective responsibility" against a civilian population further galvanised the entente. Newspapers condemned the German invasion, violence against civilians and destruction of property, which became known as
2639-404: A change in French command at Verdun from the defensive-minded Philippe Pétain to the offensive-minded Robert Nivelle , the French attempted to re-capture Fort Douaumont on 22 May but were easily repulsed. The Germans captured Fort Vaux on 7 June and with the aid of diphosgene gas, came within 1 kilometre (1,100 yd) of the last ridge before Verdun before being contained on 23 June. Over
2842-500: A core, with the first drilled bore ordnance recorded in operation near Seville in 1247. They fired lead, iron, or stone balls, sometimes large arrows and on occasions simply handfuls of whatever scrap came to hand. During the Hundred Years' War , these weapons became more common, initially as the bombard and later the cannon . Cannons were always muzzle-loaders . While there were many early attempts at breech-loading designs,
3045-412: A decisive blow to the Germans but by 20 April it was clear that the strategic intent of the offensive had not been achieved and by 25 April most of the fighting had ended. The French tactic of assault brutal et continu suited the German defensive dispositions, since much of the new construction had taken place on reverse slopes. The speed of attack and the depth of the French objectives meant that there
3248-640: A dramatic effect on the conflict as 33 divisions were released from the Eastern Front for deployment to the west. The Germans occupied almost as much Russian territory under the provisions of the Treaty of Brest-Litovsk as they did in the Second World War but this considerably restricted their troop redeployment. The Germans achieved an advantage of 192 divisions in the west to the 178 entente divisions, which allowed Germany to pull veteran units from
3451-408: A field carriage, immobility once emplaced, highly individual design, and noted unreliability (in 1460 James II , King of Scots, was killed when one exploded at the siege of Roxburgh). Their large size precluded the barrels being cast and they were constructed out of metal staves or rods bound together with hoops like a barrel, giving their name to the gun barrel . The use of the word "cannon" marks
3654-471: A fighter training school was opened at Valenciennes and better aircraft with twin guns were introduced. The result was higher losses of Allied aircraft, particularly for the British, Portuguese, Belgians and Australians who were struggling with outmoded aircraft, poor training and tactics. The Allied air successes over the Somme were not repeated. During their attack at Arras, the British lost 316 air crews and
3857-519: A high proportion of the French army was affected by the battle. By the beginning of 1917, morale was questionable, even in divisions with good combat records. Groupe d'armées du Nord on the northern flank of Groupe d'armées de Reserve (GAR) had been reduced to one army with three corps and began French operations with preliminary attacks by the Third Army on German observation points at St. Quentin on 1–4, 10 and 13 April, which took some of
4060-521: A hollow iron ball filled with pitch and fuse, designed to be fired at close range and burst on contact. The most popular in Portuguese arsenals was the berço , a 5 cm, one pounder bronze breech-loading cannon that weighted 150 kg with an effective range of 600 meters. A tactical innovation the Portuguese introduced in fort defense was the use of combinations of projectiles against massed assaults. Although canister shot had been developed in
4263-478: A lack of engineering knowledge rendered these even more dangerous to use than muzzle-loaders. In 1415, the Portuguese invaded the Mediterranean port town of Ceuta . While it is difficult to confirm the use of firearms in the siege of the city, it is known the Portuguese defended it thereafter with firearms, namely bombardas , colebratas , and falconetes . In 1419, Sultan Abu Sa'id led an army to reconquer
SECTION 20
#17327654640824466-555: A limited-objective attack on the west end of the Chemin-des-Dames, which forced the Germans to abandon their remaining positions on the ridge and retire across the Ailette valley. The British remained on the offensive for the rest of the year fighting the battles of Messines , 3rd Ypres and Cambrai . After the costly fighting at Verdun and on the Somme in 1916, General Robert Nivelle replaced Marshal Joseph Joffre as
4669-645: A long period of success before Britain resorted to the convoy system, bringing a large reduction in shipping losses. By 1917, the size of the British Army on the Western Front had grown to two-thirds of the size of the French force. In April 1917 the BEF began the Battle of Arras . The Canadian Corps and the 5th Division of the First Army, fought the Battle of Vimy Ridge , completing the capture of
4872-411: A machine-gun that shot forward through the propeller blades. This was achieved by crudely reinforcing the blades to deflect bullets. Several weeks later Garros force-landed behind German lines. His aeroplane was captured and sent to Dutch engineer Anthony Fokker , who soon produced a significant improvement, the interrupter gear , in which the machine gun is synchronised with the propeller so it fires in
5075-423: A major push. The final phase of the battle of the Somme saw the first use of the tank on the battlefield. The entente prepared an attack that would involve 13 British and Imperial divisions and four French corps. The attack made early progress, advancing 3,200–4,100 metres (3,500–4,500 yd) in places but the tanks had little effect due to their lack of numbers and mechanical unreliability. The final phase of
5278-475: A mid-19th-century 12-pounder gun , which fired a 4.1 kg (9.0 lb) round, with a kinetic energy of 240 kilojoules, or a 20th-century US battleship that fired a 1,225 kg (2,701 lb) projectile from its main battery with an energy level surpassing 350 megajoules . From the Middle Ages through most of the modern era , artillery pieces on land were moved by horse-drawn gun carriages . In
5481-407: A new system of defence. Rather than relying on a heavily fortified front line, the defence was to be arranged in a series of echelons. The front line would be a thinly manned series of outposts, reinforced by a series of strongpoints and a sheltered reserve. If a slope was available, troops were deployed along the rear side for protection. The defence became fully integrated with command of artillery at
5684-469: A period of attack and counter-attack which continued into July and August. From 20 to 26 August the French conducted the 2ème Bataille Offensive de Verdun (Second Offensive Battle of Verdun). The French captured Bois d'Avocourt, Mort-Homme, Bois Corbeaux and the Bismarck , Kronprinz and Gallwitz tunnels, which had connected the German front lines to the rear at Mort-Homme and Côte 304. On
5887-441: A position from which the French could not retreat, for reasons of strategy and national pride and thus trap the French. The town of Verdun was chosen for this because it was an important stronghold, surrounded by a ring of forts, that lay near the German lines and because it guarded the direct route to Paris. Falkenhayn limited the size of the front to 5–6 kilometres (3–4 mi) to concentrate artillery firepower and to prevent
6090-497: A prelude to a decisive infantry and cavalry assault. Physically, cannons continued to become smaller and lighter. During the Seven Years War, King Frederick II of Prussia used these advances to deploy horse artillery that could move throughout the battlefield. Frederick also introduced the reversible iron ramrod, which was much more resistant to breakage than older wooden designs. The reversibility aspect also helped increase
6293-587: A series of attacks in Flanders, beginning with the Battle of Pilckem Ridge (31 July – 2 August), followed by the Battle of Langemarck (16–18 August), The Battle of the Menin Road Ridge (20–25 September), The Battle of Polygon Wood (26 September – 3 October), The Battle of Broodseinde (4 October) The Battle of Poelcappelle (9 October) The First Battle of Passchendaele (12 October) and The Second Battle of Passchendaele (26 October – 10 November) for control of

6496-441: A single day in the history of the British Army, about 57,000. The Verdun lesson learnt, the entente tactical aim became the achievement of air superiority and until September, German aircraft were swept from the skies over the Somme. The success of the entente air offensive caused a reorganisation of the German air arm and both sides began using large formations of aircraft rather than relying on individual combat. After regrouping,
6699-507: A six-day bombardment and advanced 5 kilometres (3 mi) to capture Vimy Ridge. German reinforcements counter-attacked and pushed the French back towards their starting points because French reserves had been held back and the success of the attack had come as a surprise. By 15 May the advance had been stopped, although the fighting continued until 18 June. In May the German Army captured a French document at La Ville-aux-Bois describing
6902-565: A sixth of all rounds used by the Portuguese in Morocco were of the fused-shell variety. The new Ming Dynasty established the "Divine Engine Battalion" (神机营), which specialized in various types of artillery. Light cannons and cannons with multiple volleys were developed. In a campaign to suppress a local minority rebellion near today's Burmese border, "the Ming army used a 3-line method of arquebuses/muskets to destroy an elephant formation". When
7105-565: A strong integrating effect on emerging nation-states, as kings were able to use their newfound artillery superiority to force any local dukes or lords to submit to their will, setting the stage for the absolutist kingdoms to come. Modern rocket artillery can trace its heritage back to the Mysorean rockets of Mysore . Their first recorded use was in 1780 during the battles of the Second , Third and Fourth Mysore Wars . The wars fought between

According to two prominent historians: Between the coast and the Vosges was a westward bulge in the trench line, named the Noyon salient after the French town at the maximum point of the German advance near Compiègne . Joffre's plan for 1915 was to attack the salient on both flanks to cut it off. The Fourth Army had attacked in Champagne from 20 December 1914 – 17 March 1915 but
7511-500: A week-long artillery bombardment and accompanied by tanks. The offensive proceeded poorly as the French troops, with the help of two Russian brigades , had to negotiate rough, upward-sloping terrain in extremely bad weather. Planning had been dislocated by the voluntary German withdrawal to the Hindenburg Line. Secrecy had been compromised and German aircraft gained air superiority, making reconnaissance difficult and in places,

In some armies, the artillery arm has operated field , coastal , anti-aircraft , and anti-tank artillery; in others these have been separate arms, and with some nations coastal has been a naval or marine responsibility. In
7917-645: The Siegfriedstellung , which ran from Laffaux mill to the Chemin des Dames and joined the original defences at Courtecon. The German retirement was carried out urgently and many guns were left behind, along with "vast" stocks of munitions. The French infantry reached the new German positions with an advance of 6.4 km (4 mi). Nivelle ordered the Tenth Army forward between the Fifth and Sixth armies on 21 April and local operations were continued on
8120-612: The Battle of Mons . In the former battle the French Fifth Army was almost destroyed by the German 2nd and 3rd Armies and the latter delayed the German advance by a day. A general entente retreat followed, resulting in more clashes at the Battle of Le Cateau , the Siege of Maubeuge and the Battle of St. Quentin (also called the First Battle of Guise). The German Army came within 70 km (43 mi) of Paris but at

In the Battle of Pollilur , the Siege of Seringapatam (1792) and in Battle of Seringapatam in 1799, these rockets were used with considerable effect against the British. After the wars, several Mysore rockets were sent to England, but experiments with heavier payloads were unsuccessful. In 1804 William Congreve, considering

8729-577: The First Battle of the Marne (6–12 September), French and British troops were able to force a German retreat by exploiting a gap which appeared between the 1st and 2nd Armies, ending the German advance into France. The German Army retreated north of the Aisne and dug in there, establishing the beginnings of a static western front that was to last for the next three years. Following this German retirement,

Belgian neutrality had been guaranteed by Britain under the Treaty of London, 1839 ; this caused Britain to join the war at the expiration of its ultimatum at midnight on 4 August. Armies under German generals Alexander von Kluck and Karl von Bülow attacked Belgium on 4 August 1914. Luxembourg had been occupied without opposition on 2 August. The first battle in Belgium

The offensive was costly in manpower for both sides for relatively little gain of ground against determined German resistance but the ground captured was of great tactical importance. In the drier periods, the British advance was inexorable and during the unusually wet August and in the Autumn rains that began in early October,
9338-547: The Ieperlee from Nieuwpoort to Boezinge . Meanwhile, the British Expeditionary Force (BEF) occupied a position on the flank, having occupied a more central position. From 19 October until 22 November, the German forces made their final breakthrough attempt of 1914 during the First Battle of Ypres , which ended in a mutually-costly stalemate. After the battle, Erich von Falkenhayn judged that it

Between 1915 and 1917 there were several offensives along this front . The attacks employed massive artillery bombardments and massed infantry advances. Entrenchments, machine gun emplacements, barbed wire , and artillery repeatedly inflicted severe casualties during attacks and counter-attacks and no significant advances were made. Among
9744-698: The Treaty of Versailles in 1919. The Western Front was the place where the most powerful military forces in Europe, the German and French armies, met and where the First World War was decided. At the outbreak of the war, the German Army, with seven field armies in the west and one in the east, executed a modified version of the Schlieffen Plan , bypassing French defenses along the common border by moving quickly through neutral Belgium, and then turning southwards to attack France and attempt to encircle
9947-712: The War Office claimed, with some justification, that this withdrawal resulted from the casualties the Germans received during the Battles of the Somme and Verdun, despite the entente suffering greater losses. On 6 April the United States declared war on Germany. In early 1915, following the sinking of the Lusitania , Germany had stopped unrestricted submarine warfare in the Atlantic because of concerns of drawing
10150-407: The catapult , onager , trebuchet , and ballista , are also referred to by military historians as artillery. During medieval times, more types of artillery were developed, most notably the counterweight trebuchet. Traction trebuchets, using manpower to launch projectiles, have been used in ancient China since the 4th century as anti-personnel weapons. The much more powerful counterweight trebuchet

These land versions of artillery were dwarfed by railway guns ; the largest of these large-calibre guns ever conceived – Project Babylon of the Supergun affair – was theoretically capable of putting a satellite into orbit . Artillery used by naval forces has also changed significantly, with missiles generally replacing guns in surface warfare . Over

#173276546408210556-563: The siege of Constantinople in 1453 weighed 19 tons , took 200 men and sixty oxen to emplace, and could fire just seven times a day. The Fall of Constantinople was perhaps "the first event of supreme importance whose result was determined by the use of artillery" when the huge bronze cannons of Mehmed II breached the city's walls, ending the Byzantine Empire , according to Sir Charles Oman . Bombards developed in Europe were massive smoothbore weapons distinguished by their lack of

After marching through Belgium, Luxembourg and the Ardennes , the Germans advanced into northern France in late August, where they met the French Army, under Joseph Joffre , and the divisions of the British Expeditionary Force under Field Marshal Sir John French . A series of engagements known as the Battle of the Frontiers ensued, which included the Battle of Charleroi and
10962-467: The 13-foot-wide (4 m) German tank traps. Special "grapnel tanks" towed hooks to pull away the German barbed wire. The attack was a great success for the British, who penetrated further in six hours than at the Third Ypres in four months, at a cost of only 4,000 British casualties. The advance produced an awkward salient and a surprise German counter-offensive began on 30 November, which drove back
11165-442: The 15th century. The development of specialized pieces—shipboard artillery, howitzers and mortars —was also begun in this period. More esoteric designs, like the multi-barrel ribauldequin (known as "organ guns"), were also produced. The 1650 book by Kazimierz Siemienowicz Artis Magnae Artilleriae pars prima was one of the most important contemporary publications on the subject of artillery. For over two centuries this work
11368-551: The 16th century unequalled by contemporary European neighbours, in part due to the experience gained in intense fighting in Morocco, which served as a proving ground for artillery and its practical application, and made Portugal a forerunner in gunnery for decades. During the reign of King Manuel (1495–1521) at least 2017 cannon were sent to Morocco for garrison defense, with more than 3000 cannon estimated to have been required during that 26-year period. An especially noticeable division between siege guns and anti-personnel guns enhanced
11571-440: The 16th century, cannon were largely (though not entirely) displaced from the battlefield—the cannon were too slow and cumbersome to be used and too easily lost to a rapid enemy advance. The combining of shot and powder into a single unit, a cartridge, occurred in the 1620s with a simple fabric bag, and was quickly adopted by all nations. It speeded loading and made it safer, but unexpelled bag fragments were an additional fouling in
11774-431: The 20th century, target acquisition devices (such as radar) and techniques (such as sound ranging and flash spotting ) emerged, primarily for artillery. These are usually utilized by one or more of the artillery arms. The widespread adoption of indirect fire in the early 20th century introduced the need for specialist data for field artillery, notably survey and meteorological, and in some armies, provision of these are

By the end of May more units of the 5th, 6th, 13th, 35th, 43rd, 62nd, 77th and 170th divisions mutinied; revolts occurred in 21 divisions in May. The offensive was suspended on 9 May. The army, politicians and public were stunned by

From 16 April to 10 May the Fourth, Fifth, Sixth and Tenth armies took 28,500 prisoners and 187 guns. The advance of the Sixth Army was one of the largest made by a French army since trench warfare began. After the substitution of limited objectives in favour of breakthrough attempts,

The experienced French forces were successful in advancing but the British artillery cover had neither blasted away barbed wire, nor destroyed German trenches as effectively as was planned. They suffered the greatest number of casualties (killed, wounded and missing) in

The Germans realised that the use of tanks by the entente posed a new threat to any defensive strategy they might mount. The battle had also seen the first mass use of German Stosstruppen on the Western front in the attack, who used infantry infiltration tactics to penetrate British defences, bypassing resistance and quickly advancing into
13398-558: The British launched an offensive in Flanders, in part to take the pressure off the French armies on the Aisne, after the French part of the Nivelle Offensive failed to achieve the strategic victory that had been planned and French troops began to mutiny . The offensive began on 7 June, with a British attack on Messines Ridge , south of Ypres, to retake the ground lost in the First and Second battles in 1914. Since 1915 specialist Royal Engineer tunnelling companies had been digging tunnels under

Following the successful entente attack and penetration of the German defences at Cambrai, Ludendorff and Hindenburg determined that the only opportunity for German victory lay in a decisive attack along the Western front during the spring, before American manpower became overwhelming. On 3 March 1918, the Treaty of Brest-Litovsk was signed and Russia withdrew from the war. This would now have

German attacks on 30 to 31 May prompted a French counter-attack on 18 June and another German attack on 21 June. The main German effort was made in the centre, with five attacks against the Californie plateau from 3 to 6 June, followed by another German attack on 17 June. On 25 June,

The same month, the French Commander-in-chief , General Robert Nivelle, ordered a new offensive against the German trenches, promising that it would end the war within 48 hours. The 16 April attack, dubbed the Nivelle Offensive (also known as the Second Battle of the Aisne ), would be 1.2 million men strong, preceded by

On 4 July, a German attack began on a 11 mi (17 km) front between Craonne and Cerny, followed by French counter-attacks on 7 and 9 July; from 5 May the Germans attacked seventy times in eighty days. German attacks were conducted against Côte 304 and Mort Homme on 29 and 30 June, beginning

The resistance of the German 4th Army , unusually wet weather, the onset of winter and the diversion of British and French resources to Italy, following the Austro-German victory at the Battle of Caporetto (24 October – 19 November) allowed the Germans to avoid a general withdrawal, which had seemed inevitable to them early in October. The campaign ended in November when

When she led the assault on Paris, Joan faced stiff artillery fire, especially from the suburb of St. Denis, which ultimately led to her defeat in this battle. In April 1430, she went to battle against the Burgundians, whose support was purchased by the English. At this time, the Burgundians had
15225-601: The French Third Army of Groupe d'armées du Nord (GAN, Northern Army Group) captured the German defences west of the Hindenburg Line (Siegfriedstellung) near St Quentin from 1 to 4 April, before further attacks were repulsed. The British Third and First armies achieved the deepest advance since trench warfare began, along the Scarpe river in the Battle of Arras , which inflicted many casualties on
15428-496: The French army had "quickly overcome its depression". The Battle of La Malmaison ( Bataille de la Malmaison 23–27 October 1917) led to the French capture of the village and fort of La Malmaison and control of the Chemin des Dames ridge. Boehn chose to defend the front positions, rather than treat them as an advanced zone and conduct the main defence north of the Canal de l'Oise à l'Aisne . Gas bombardments on low-lying land near
15631-457: The French countered by deploying escadrilles de chasse with superior Nieuport fighters and the air over Verdun turned into a battlefield as both sides fought for air superiority . The Battle of Verdun began on 21 February 1916 after a nine-day delay due to snow and blizzards. After a massive eight-hour artillery bombardment, the Germans did not expect much resistance as they slowly advanced on Verdun and its forts. Sporadic French resistance
15834-595: The French on the Chemin des Dames ridge (the Second Battle of the Aisne ). A subsidiary attack was to be made by the Fourth Army (the Third Battle of Champagne). The final stage of the offensive was to follow the meeting of the British and French armies, having broken through the German lines, to pursue the defeated German armies towards the German frontier. The Franco-British attacks were tactically successful;
16037-515: The French suffered 117,000 casualties including 32,000 killed in the first few days but that the effect on military and civilian morale was worse than the casualties. In 1962, Gerald Nicholson , the Canadian official historian, recorded c. 163,000 German casualties and 187,000 French casualties. Most of the new French Schneider tanks were destroyed by artillery fire. In 2005, Doughty quoted figures of 134,000 French casualties on
16240-400: The French trenches. The green-yellow cloud started killing some defenders and those in the rear fled in panic , creating an undefended 3.7-mile (6 km) gap in the entente line. The Germans were unprepared for the level of their success and lacked sufficient reserves to exploit the opening. Canadian troops on the right drew back their left flank and halted the German advance. The gas attack
16443-578: The French were not able to attack in Artois at the same time. The Tenth Army formed the northern attack force and was to attack eastwards into the Douai plain on a 16 km (9.9 mi) front between Loos and Arras. On 10 March, as part of the larger offensive in the Artois region, the British Army fought the Battle of Neuve Chapelle to capture Aubers Ridge. The assault was made by four divisions on
16646-686: The German alliance), the final lines were occupied with the armies of each nation defending a part of the front. From the coast in the north, the primary forces were from Belgium, the British Empire and then France. Following the Battle of the Yser in October, the Belgian army controlled a 35 km (22 mi) length of West Flanders along the coast, known as the Yser Front , along the Yser and
16849-548: The German defences in front of the Siegfriedstellung (Hindenburg Line) in preliminary operations. The main attack on 13 April made very little progress, against a German defence relying mainly on machine-gun fire and local counter-attacks. On 9 April the British Third Army attacked to the east of Arras from Croisilles to Ecurie, against Observation Ridge, north of the Arras–Cambrai road and then towards Feuchy and
17052-589: The German defences on the Aisne front within 48 hours, with casualties expected to be around 10,000 men. A preliminary attack was to be made by the French Third Army at St Quentin and the British First , Third and Fifth armies at Arras , to capture high ground and divert German reserves from the French fronts on the Aisne and in Champagne . The main offensive was to be delivered by
17255-404: The German front line. On 25 February the German armies west of the line began Operation Alberich a withdrawal to the line and completed the retirement on 5 April, leaving a supply desert of scorched earth to be occupied by the entente. This withdrawal negated the French strategy of attacking both flanks of the Noyon salient, as it no longer existed. The British continued offensive operations as
17458-521: The German second and third lines. To the south of the road the initial objective was Devil's Wood to Tilloy-lès-Mofflaines and Bois des Boeufs, with a final objective of the Monchyriegel (Monchy switch line) between Wancourt and Feuchy. The Third Army attack on the German defences either side of the Scarpe river penetrated 6,000 yd (3.4 mi; 5.5 km), the furthest advance achieved since
17661-415: The German second position been reached. On the second day Nivelle ordered the Fifth Army to attack north-eastwards to reinforce success, believing that the Germans intended to hold the ground in front of the Sixth Army. The Fifth Army was not able substantially to advance on 17 April but the Sixth Army, which had continued to attack overnight, forced a German withdrawal from the area of Braye–Condé–Laffaux to
17864-404: The Germans achieved only costly defensive successes, which led the German commanders in early October to begin preparations for a general retreat. Both sides lost a combined total of over a half million men during this offensive. The battle has become a byword among some British revisionist historians for bloody and futile slaughter, whilst the Germans called Passchendaele "the greatest martyrdom of
18067-476: The Germans adopted a new defence-in-depth scheme that consisted of a series of defensive zones and positions with a depth of up to 8.0 km (5 mi). On 25 September, the British began the Battle of Loos , part of the Third Battle of Artois, which was meant to supplement the larger Champagne attack. The attack was preceded by a four-day artillery bombardment of 250,000 shells and a release of 5,100 cylinders of chlorine gas. The attack involved two corps in
18270-462: The Germans on 20 August. Although the German army bypassed Antwerp, it remained a threat to their flank. Another siege followed at Namur, lasting from about 20–23 August. The French deployed five armies on the frontier. The French Plan XVII was intended to bring about the capture of Alsace–Lorraine . On 7 August, the VII Corps attacked Alsace to capture Mulhouse and Colmar. The main offensive
18473-477: The Germans, attracted reserves and captured Vimy Ridge to the north. The main French offensive on the Aisne began on 16 April and also achieved considerable tactical success but the attempt to force a strategically decisive battle on the Germans was a costly failure and by 25 April the main offensive had been suspended. The failure of the Nivelle strategy and the high number of French casualties led to mutinies ,
18676-684: The Javanese were considered excellent in casting artillery, and in the knowledge of using it. In 1513, the Javanese fleet led by Pati Unus sailed to attack Portuguese Malacca "with much artillery made in Java, for the Javanese are skilled in founding and casting, and in all works in iron , over and above what they have in India ". By the early 16th century, the Javanese had already started locally-producing large guns, which were dubbed "sacred cannon[s]" or "holy cannon[s]" and have survived up to
18879-580: The Lodz offensive in Poland (11–25 November), Falkenhayn hoped that the Russians would be made amenable to peace overtures. In his discussions with Bethmann Hollweg, Falkenhayn viewed Germany and Russia as having no insoluble conflict and that the real enemies of Germany were France and Britain. A peace with only a few annexations of territory also seemed possible with France and that with Russia and France out of
19082-717: The Mysorian rockets to have too short a range (less than 1,000 yards) developed rockets in numerous sizes with ranges up to 3,000 yards and eventually utilizing iron casing as the Congreve rocket which were used effectively during the Napoleonic Wars and the War of 1812 . With the Napoleonic Wars, artillery experienced changes in both physical design and operation. Rather than being overseen by "mechanics", artillery
19285-525: The Portuguese and Spanish arrived at Southeast Asia, they found that the local kingdoms were already using cannons. Portuguese and Spanish invaders were unpleasantly surprised and even outgunned on occasion. Duarte Barbosa ca. 1514 said that the inhabitants of Java were great masters in casting artillery and very good artillerymen. They made many one-pounder cannons (cetbang or rentaka ), long muskets, spingarde (arquebus), schioppi (hand cannon), Greek fire , guns (cannons), and other fire-works. In all aspects
19488-526: The Scarpe to Vimy Ridge. The crest of the ridge was captured at about 1:00 p.m. in an advance which penetrated about 4,000 yd (2.3 mi; 3.7 km) during the day. German reserves had been held too far back from the front and did not begin to reach the battlefield until the evening, when they were able only to reinforce the survivors of the front defences in improvised positions. The British engaged in several general attacks and limited attacks, which took more ground but became increasingly costly, against
19691-465: The Scarpe; accommodation for 150,000 men was identified in reconnaissance photographs. On 6 April a division was seen encamped near Arras, troop and transport columns crowded the streets while more narrow-gauge railways and artillery were seen to have moved closer to the front. British aerial activity opposite the 6th Army greatly increased and by 6 April Ludendorff was certain that an attack was imminent. By early April German air reinforcements had arrived
19894-424: The Sixth Army (General Charles Mangin ) and the Tenth Army (General Denis Duchêne ). Forty-nine infantry and five cavalry divisions were massed on the Aisne front with 5,300 guns. The ground at Brimont began to rise to the west towards Craonne and then reached a height of 180 m (590 ft) along a plateau which continued westwards to Fort Malmaison. The French held a bridgehead 20 km (12 mi) wide on
20097-499: The United States into the conflict. With the growing discontent of the German public due to the food shortages, the government resumed unrestricted submarine warfare in February 1917. They calculated that a successful submarine and warship siege of Britain would force that country out of the war within six months, while American forces would take a year to become a serious factor on the Western Front. The submarine and surface ships had
20300-447: The Western Front was against the French near the Belgian town of Ypres . The Germans had already deployed gas against the Russians in the east at the Battle of Humin-Bolimów . Despite the German plans to maintain the stalemate with the French and British, Albrecht, Duke of Württemberg , commander of the 4th Army planned an offensive at Ypres, site of the First Battle of Ypres in November 1914. The Second Battle of Ypres , April 1915,
20503-417: The army group commanders and the British, Alexandre Ribot , the new French Prime Minister supported the plan. Nivelle offered his resignation but it was refused, despite Nivelle's authority having been undermined. Preparing the Nivelle Offensive was a huge and costly undertaking, involving c. 1.2 million troops and 7,000 artillery pieces on a front between Reims and Roye . The principal effort
20706-530: The army. These may be grouped into brigades; the Russian army also groups some brigades into artillery divisions, and the People's Liberation Army has artillery corps. The term "artillery" also designates a combat arm of most military services when used organizationally to describe units and formations of the national armed forces that operate the weapons. During military operations , field artillery has
20909-401: The battle continued throughout July and August, with some success for the British despite the reinforcement of the German lines. By August, General Haig had concluded that a breakthrough was unlikely and instead, switched tactics to a series of small unit actions. The effect was to straighten out the front line, which was thought necessary in preparation for a massive artillery bombardment with
21112-499: The battle took place in October and early November, again producing limited gains with heavy loss of life. All told, the Somme battle had made penetrations of only 8 kilometres (5 mi) and failed to reach the original objectives. The British had suffered about 420,000 casualties and the French around 200,000. It is estimated that the Germans lost 465,000, although this figure is controversial. The Somme led directly to major new developments in infantry organisation and tactics; despite
21315-461: The beginning German machine-gunners were able to engage the French infantry and inflict many casualties, although German artillery-fire was far less destructive. Courcy on the right flank was captured but the advance was stopped at the Aisne–Marne canal. The canal was crossed further north and Bermericourt was captured against a determined German defence. From Bermericourt to the Aisne the French attack
21518-427: The beginning of trench warfare. Most of the objectives had been reached by the evening of 10 April, except for the line between Wancourt and Feuchy around Neuville-Vitasse . The village fell that day, although the German garrisons in some parts of Monchyriegel held out for several more days. The Third Army consolidated and then advanced on Monchy-le-Preux . To the north the First Army attacked from Ecurie north of
21721-619: The bronze "thousand ball thunder cannon", an early example of field artillery . These small, crude weapons diffused into the Middle East (the madfaa ) and reached Europe in the 13th century, in a very limited manner. In Asia, Mongols adopted the Chinese artillery and used it effectively in the great conquest . By the late 14th century, Chinese rebels used organized artillery and cavalry to push Mongols out. As small smooth-bore barrels, these were initially cast in iron or bronze around
21924-420: The canal dispersed very slowly and became so dense that the carriage of ammunition and supplies to the front was made impossible. Eingreif divisions were distributed in battalions along the front line and caught in the French bombardments, where the infantry shelters had been identified by French air reconnaissance and systematically destroyed. Zero hour had been set for 5:45 a.m. but the French intercepted
22127-456: The chain of events and on 16 May, Nivelle was sacked and moved to North Africa. He was replaced by the considerably more cautious Pétain, with Foch as chief of the general staff; the new commanders abandoned the strategy of decisive battle for one of recuperation and defence, to avoid high casualties and to restore morale.A record 27,000 French soldiers deserted in 1917; Pétain had 40–62 mutineers shot as examples and introduced reforms to improve
22330-506: The commander of the French armies on the Western Front in December. Nivelle claimed that a massive barrage on German lines would bring France victory in 48 hours. The Russian Revolution , the German withdrawal to the Hindenburg Line and the likelihood of a declaration of war by the US, made some assumptions of the plan obsolete. At a meeting on 6 April, despite the doubts of other politicians,
22533-431: The course of military history, projectiles were manufactured from a wide variety of materials, into a wide variety of shapes, using many different methods in which to target structural/defensive works and inflict enemy casualties . The engineering applications for ordnance delivery have likewise changed significantly over time, encompassing some of the most complex and advanced technologies in use today. In some armies,
22736-413: The creeping barrage moved too fast for the French troops. Within a week the French suffered 120,000 casualties. Despite the casualties and his promise to halt the offensive if it did not produce a breakthrough, Nivelle ordered the attack to continue into May. On 3 May the weary French 2nd Colonial Division, veterans of the Battle of Verdun, refused orders, arriving drunk and without their weapons. Lacking
22939-537: The cumulative weakening of the armies in the west led to the return of mobility in 1918. The German spring offensive of 1918 was made possible by the Treaty of Brest-Litovsk that ended the war of the Central Powers against Russia and Romania on the Eastern Front . Using short, intense "hurricane" bombardments and infiltration tactics , the German armies moved nearly 100 kilometres (60 miles) to
23142-461: The current context originated in the Middle Ages . One suggestion is that it comes from French atelier , meaning the place where manual work is done. Another suggestion is that it originates from the 13th century and the Old French artillier , designating craftsmen and manufacturers of all materials and warfare equipments (spears, swords, armor, war machines); and, for the next 250 years,
23345-511: The defense in a siege was lost. Cannons during this period were elongated, and the recipe for gunpowder was improved to make it three times as powerful as before. These changes led to the increased power in the artillery weapons of the time. Joan of Arc encountered gunpowder weaponry several times. When she led the French against the English at the Battle of Tourelles, in 1430, she faced heavy gunpowder fortifications, and yet her troops prevailed in that battle. In addition, she led assaults against
23548-415: The development of artillery ordnance, systems, organizations, and operations until the present, with artillery systems capable of providing support at ranges from as little as 100 m to the intercontinental ranges of ballistic missiles . The only combat in which artillery is unable to take part is close-quarters combat , with the possible exception of artillery reconnaissance teams. The word as used in
23751-478: The dismissal of Nivelle, his replacement by Philippe Pétain and the adoption of a defensive strategy by the French, while their armies recuperated and rearmed. Fighting known as the Battle of the Observatories continued for local advantage all summer on the Chemin des Dames and along the Moronvilliers heights east of Reims . In late October, the French conducted the Battle of La Malmaison (23–27 October),
23954-464: The divisional level. Members of the German high command viewed this new scheme with some favour and it later became the basis of an elastic defence in depth doctrine against entente attacks. During the autumn of 1915, the " Fokker Scourge " began to have an effect on the battlefront as entente reconnaissance aircraft were nearly driven from the skies. These reconnaissance aircraft were used to direct gunnery and photograph enemy fortifications but now
24157-453: The early 15th century, the Portuguese were the first to employ it extensively, and Portuguese engineers invented a canister round which consisted of a thin lead case filled with iron pellets, that broke up at the muzzle and scattered its contents in a narrow pattern. An innovation which Portugal adopted in advance of other European powers was fuse-delayed action shells, and were commonly used in 1505. Although dangerous, their effectiveness meant
24360-479: The east of Reims which became known as Bataille des Monts , with the VIII, XVII and XII Corps on an 11 km (6.8 mi) front. The attack began at 4:45 a.m. in cold rain alternating with snow showers. The right flank guard to the east of Suippes was established by the 24th Division and Aubérive on the east bank of the river and the 34th Division took Mont Cornillet and Mont Blond. The Monts were held against
24563-414: The end of the 14th century, cannons were only powerful enough to knock in roofs, and could not penetrate castle walls. However, a major change occurred between 1420 and 1430, when artillery became much more powerful and could now batter strongholds and fortresses quite efficiently. The English, French, and Burgundians all advanced in military technology, and as a result the traditional advantage that went to
24766-457: The end of the war. It also inaugurated the cult of the ace , the most famous being Manfred von Richthofen (the Red Baron). Contrary to the myth, anti-aircraft fire claimed more kills than fighters. The final entente offensive of the spring was the Second Battle of Artois , an offensive to capture Vimy Ridge and advance into the Douai plain. The French Tenth Army attacked on 9 May after
24969-433: The enemy by obscuring their view. Fire may be directed by an artillery observer or another observer, including crewed and uncrewed aircraft, or called onto map coordinates . Military doctrine has had a significant influence on the core engineering design considerations of artillery ordnance through its history, in seeking to achieve a balance between the delivered volume of fire with ordnance mobility. However, during
25172-503: The entente were nearly blinded by German fighters. However, the impact of German air superiority was diminished by their primarily defensive doctrine in which they tended to remain over their own lines, rather than fighting over entente held territory. In September 1915 the entente launched another offensive, with the French Third Battle of Artois , Second Battle of Champagne and the British at Loos. The French had spent
25375-567: The failure on the Shell Crisis of 1915 , despite the early success. All sides had signed the Hague Conventions of 1899 and 1907 , which prohibited the use of chemical weapons in warfare. In 1914, there had been small-scale attempts by both the French and Germans to use various tear gases , which were not strictly prohibited by the early treaties but which were also ineffective. The first use of more lethal chemical weapons on
25578-410: The fallen city, and Marinids brought cannons and used them in the assault on Ceuta. Finally, hand-held firearms and riflemen appear in Morocco, in 1437, in an expedition against the people of Tangiers . It is clear these weapons had developed into several different forms, from small guns to large artillery pieces. The artillery revolution in Europe caught on during the Hundred Years' War and changed
25781-406: The first warning of an attack on 16 April. German artillery-observation aircraft crews were able to range guns on terrain features, areas and targets before the offensive began so that the positions of the heaviest French guns, advanced batteries and areas not under French bombardment could be reported quickly along with the accuracy of German return-fire. Ground communication with the German artillery
25984-417: The fronts of the Fourth and Fifth armies with little success. On 4 to 5 May Brimont was to be captured, which would have been of great tactical value to the French; the attack was postponed on the orders of the French government and was then cancelled. The Tenth Army captured the Californie plateau on the Chemin des Dames and the Sixth Army captured the Siegfriedstellung for 4.0 km (2.5 mi) along
26187-494: The ground breaking legs and ankles. The development of modern artillery occurred in the mid to late 19th century as a result of the convergence of various improvements in the underlying technology. Advances in metallurgy allowed for the construction of breech-loading rifled guns that could fire at a much greater muzzle velocity . After the British artillery was shown up in the Crimean War as having barely changed since
26390-423: The gun barrel and a new tool—a worm —was introduced to remove them. Gustavus Adolphus is identified as the general who made cannon an effective force on the battlefield—pushing the development of much lighter and smaller weapons and deploying them in far greater numbers than previously. The outcome of battles was still determined by the clash of infantry. Shells, explosive-filled fused projectiles, were in use by
26593-497: The intervals when the blades of the propeller are out of the line of fire. This advance was quickly ushered into service, in the Fokker E.I ( Eindecker , or monoplane, Mark 1), the first single seat fighter aircraft to combine a reasonable maximum speed with an effective armament. Max Immelmann scored the first confirmed kill in an Eindecker on 1 August. Both sides developed improved weapons, engines, airframes and materials, until
26796-418: The introduction in the 15th century of a dedicated field carriage with axle, trail and animal-drawn limber—this produced mobile field pieces that could move and support an army in action, rather than being found only in the siege and static defenses. The reduction in the size of the barrel was due to improvements in both iron technology and gunpowder manufacture, while the development of trunnions —projections at
26999-470: The introduction of a gun shield necessary. The problems of how to employ a fixed or horse-towed gun in mobile warfare necessitated the development of new methods of transporting the artillery into combat. Two distinct forms of artillery were developed: the towed gun, used primarily to attack or defend a fixed-line; and the self-propelled gun, intended to accompany a mobile force and to provide continuous fire support and/or suppression. These influences have guided
27202-486: The largest share of an army's total firepower. Originally, the word "artillery" referred to any group of soldiers primarily armed with some form of manufactured weapon or armour. Since the introduction of gunpowder and cannon, "artillery" has largely meant cannon, and in contemporary usage, usually refers to shell -firing guns , howitzers , and mortars (collectively called barrel artillery , cannon artillery or gun artillery ) and rocket artillery . In common speech,
27405-691: The line and retrain them as Stosstruppen (40 infantry and 3 cavalry divisions were retained for German occupation duties in the east). Artillery Artillery are ranged weapons that launch munitions far beyond the range and power of infantry firearms . Early artillery development focused on the ability to breach defensive walls and fortifications during sieges , and led to heavy, fairly immobile siege engines . As technology improved, lighter, more mobile field artillery cannons developed for battlefield use. This development continues today; modern self-propelled artillery vehicles are highly mobile weapons of great versatility generally providing
27608-701: The main theatres of war during the First World War . Following the outbreak of war in August 1914, the German Army opened the Western Front by invading Luxembourg and Belgium , then gaining military control of important industrial regions in France . The German advance was halted with the Battle of the Marne . Following the Race to the Sea , both sides dug in along a meandering line of fortified trenches , stretching from
27811-402: The main assault and two corps performing diversionary attacks at Ypres. The British suffered heavy losses, especially due to machine gun fire during the attack and made only limited gains before they ran out of shells. A renewal of the attack on 13 October fared little better. In December, French was replaced by General Douglas Haig as commander of the British forces. Falkenhayn believed that
28014-454: The means to punish an entire division, its officers did not immediately implement harsh measures against the mutineers. Mutinies occurred in 54 French divisions and 20,000 men deserted. Other entente forces attacked but suffered massive casualties. Appeals to patriotism and duty followed, as did mass arrests and trials. The French soldiers returned to defend their trenches but refused to participate in further offensive action. On 15 May Nivelle
28217-451: The modern period, the consideration of protecting the gunners also arose due to the late-19th-century introduction of the new generation of infantry weapons using conoidal bullet , better known as the Minié ball , with a range almost as long as that of field artillery. The gunners' increasing proximity to and participation in direct combat against other combat arms and attacks by aircraft made
28420-422: The more deadly phosgene gas in 1915, then the infamous mustard gas in 1917, which could linger for days and could kill slowly and painfully. Countermeasures also improved and the stalemate continued. Specialised aeroplanes for aerial combat were introduced in 1915. Aircraft were already in use for scouting and on 1 April, the French pilot Roland Garros became the first to shoot down an enemy aircraft by using
28623-452: The most costly of these offensives were the Battle of Verdun , in 1916, with a combined 700,000 casualties, the Battle of the Somme , also in 1916, with more than a million casualties, and the Battle of Passchendaele , in 1917, with 487,000 casualties. To break the deadlock of the trench warfare on the Western Front, both sides tried new military technology , including poison gas , aircraft, and tanks . The adoption of better tactics and
28826-444: The north bank of the Aisne, south of the Chemin des Dames, from Berry-au-Bac to Fort Condé on the road to Soissons. German air reconnaissance was possible close to the front although longer-range sorties were impossible to protect because of the greater number of Allied aircraft. The qualitative superiority of German fighters enabled German air observers on short-range sorties to detect British preparations for an attack on both sides of
29029-468: The nuts, bolts and screws made their mass production and repair much easier. While the Gribeauval system made for more efficient production and assembly, the carriages used were heavy and the gunners were forced to march on foot (instead of riding on the limber and gun as in the British system). Each cannon was named for the weight of its projectiles, giving us variants such as 4, 8, and 12, indicating
29232-487: The opposing forces made reciprocal outflanking manoeuvres, known as the Race to the Sea and quickly extended their trench systems from the Swiss frontier to the North Sea . The territory occupied by Germany held 64 percent of French pig-iron production , 24 percent of its steel manufacturing and 40 percent of the coal industry – dealing a serious blow to French industry. On the entente side (those countries opposing
29435-459: The original aim of capturing the ridges east of Ypres then advancing to Roulers and Thourout to close the main rail line supplying the German garrisons on the Western front north of Ypres. If successful the northern armies were then to capture the German submarine bases on the Belgian coast. It was later restricted to advancing the British Army onto the ridges around Ypres, as the unusually wet weather slowed British progress. The Canadian Corps relieved
29638-701: The present day - though in limited numbers. These cannons varied between 180 and 260 pounders, weighing anywhere between 3–8 tons, measuring between 3–6 m. Between 1593 and 1597, about 200,000 Korean and Chinese troops which fought against Japan in Korea actively used heavy artillery in both siege and field combat. Korean forces mounted artillery in ships as naval guns , providing an advantage against Japanese navy which used Kunikuzushi (国崩し – Japanese breech-loading swivel gun ) and Ōzutsu (大筒 – large size Tanegashima ) as their largest firearms. Bombards were of value mainly in sieges . A famous Turkish example used at
29841-468: The rate of fire, since a soldier would no longer have to worry about what end of the ramrod they were using. Jean-Baptiste de Gribeauval , a French artillery engineer, introduced the standardization of cannon design in the mid-18th century. He developed a 6-inch (150 mm) field howitzer whose gun barrel, carriage assembly and ammunition specifications were made uniform for all French cannons. The standardized interchangeable parts of these cannons down to
30044-406: The responsibility of the artillery arm. The majority of combat deaths in the Napoleonic Wars , World War I , and World War II were caused by artillery. In 1944, Joseph Stalin said in a speech that artillery was "the god of war". Although not called by that name, siege engines performing the role recognizable as artillery have been employed in warfare since antiquity. The first known catapult
30247-450: The ridge and the Third Army to the south achieved the deepest advance since trench warfare began. Later attacks were confronted by German reinforcements defending the area using the lessons learned on the Somme in 1916. British attacks were contained and, according to Gary Sheffield, a greater rate of daily loss was inflicted on the British than in "any other major battle". During the winter of 1916–1917, German air tactics had been improved,
30450-519: The ridge had been reinforced with machine-gun posts; the German divisional commanders chose to fight in the front line and few of the Eingreif divisions were needed in the first few days. On 3 May the French 2nd Division refused to follow orders to attack and this mutiny soon spread throughout the army. Towards the end of the offensive, the 2nd Division arrived on the battlefield drunk and without weapons. From 16 to 17 May, there were disturbances in
30653-511: The ridge, German artillery and machine-guns on the valley floor had direct observation and the British artillery was less able to provide covering fire. Fighting continued on the lower slopes on the east side of the ridge until 14 June. The attack prepared the way for the main attack later in the summer, by removing the Germans from the dominating ground on the southern face of the Ypres salient, which they had held for two years. The British conducted
30856-457: The ridge, and about 500 t (490 long tons) of explosives had been planted in 21 mines under the German defences. Following several weeks of bombardment, the explosives in 19 of these mines were detonated, killing up to 7,000 German troops. The infantry advance that followed relied on three creeping barrages which the British infantry followed to capture the plateau and the east side of the ridge in one day. German counter-attacks were defeated and
31059-601: The ridges south and east of the Belgian city of Ypres (Ieper) in West Flanders . The next stage of the Allied strategy was an advance to Torhout – Couckelaere , to close the German-controlled railway running through Roulers and Thourout. Further operations and a British supporting attack along the Belgian coast from Nieuwpoort, combined with an Operation Hush , an amphibious landing, were then to reach Bruges
31262-559: The right bank, Bois Talou, Champneuville, Côte 344, part of Bois Fosse, Bois Chaume and Mormont Farm were captured. Next day Côte 304, Samogneux and Régnieville fell and on 26 August the French reached the southern outskirts of Beaumont. By 26 August the French had captured 9,500 prisoners, thirty guns, 100 trench mortars and 242 machine-guns. By 9 September, the French had taken more than 10,000 prisoners; fighting continued with German counter-attacks on 21, 22, 27 and 28 August, 24 September and 1 October. Ludendorff wrote that
31465-548: The role of providing support to other arms in combat or of attacking targets, particularly in-depth. Broadly, these effects fall into two categories, aiming either to suppress or neutralize the enemy, or to cause casualties, damage, and destruction. This is mostly achieved by delivering high-explosive munitions to suppress, or inflict casualties on the enemy from casing fragments and other debris and from blast , or by destroying enemy positions, equipment, and vehicles. Non-lethal munitions, notably smoke, can also suppress or neutralize
31668-735: The sense of the word "artillery" covered all forms of military weapons. Hence, the naming of the Honourable Artillery Company , which was essentially an infantry unit until the 19th century. Another suggestion is that it comes from the Italian arte de tirare (art of shooting), coined by one of the first theorists on the use of artillery, Niccolò Tartaglia . The term was used by Girolamo Ruscelli (died 1566) in his Precepts of Modern Militia published posthumously in 1572. Mechanical systems used for throwing ammunition in ancient warfare, also known as " engines of war ", like
31871-466: The side of the cannon as an integral part of the cast—allowed the barrel to be fixed to a more movable base, and also made raising or lowering the barrel much easier. The first land-based mobile weapon is usually credited to Jan Žižka , who deployed his oxen-hauled cannon during the Hussite Wars of Bohemia (1418–1424). However, cannons were still large and cumbersome. With the rise of musketry in
32074-476: The siege of Roxburgh Castle in 1460. The able use of artillery supported to a large measure the expansion and defense of the Portuguese Empire , as it was a necessary tool that allowed the Portuguese to face overwhelming odds both on land and sea from Morocco to Asia. In great sieges and in sea battles, the Portuguese demonstrated a level of proficiency in the use of artillery after the beginning of
32277-454: The siege sixty-nine guns in fifteen separate batteries and trained them at the walls of the city. The barrage of Ottoman cannon fire lasted forty days, and they are estimated to have fired 19,320 times. Artillery also played a decisive role in the Battle of St. Jakob an der Birs of 1444. Early cannon were not always reliable; King James II of Scotland was killed by the accidental explosion of one of his own cannon, imported from Flanders, at
32480-462: The south of Ypres, where the 16th (Irish) Division withstood several German gas attacks. The British retaliated, developing their own chlorine gas and using it at the Battle of Loos in September 1915. Fickle winds and inexperience led to more British casualties from the gas than German. French, British and German forces all escalated the use of gas attacks through the rest of the war, developing
32683-481: The southern flank of the Gheluvelt plateau was protected from German observation. On 11 July 1917, during Unternehmen Strandfest (Operation Beachparty) at Nieuport on the coast, the Germans introduced a new weapon into the war when they fired a powerful blistering agent Sulfur mustard (Yellow Cross) gas. The artillery deployment allowed heavy concentrations of the gas to be used on selected targets. Mustard gas
32886-544: The spring, entente commanders had been concerned about the ability of the French Army to withstand the enormous losses at Verdun. The original plans for an attack around the River Somme were modified to let the British make the main effort. This would serve to relieve pressure on the French, as well as the Russians who had also suffered great losses. On 1 July, after a week of heavy rain, British divisions in Picardy began
33089-670: The strongest and largest gunpowder arsenal among the European powers, and yet the French, under Joan of Arc's leadership, were able to beat back the Burgundians and defend themselves. As a result, most of the battles of the Hundred Years' War that Joan of Arc participated in were fought with gunpowder artillery. The army of Mehmet the Conqueror , which conquered Constantinople in 1453, included both artillery and foot soldiers armed with gunpowder weapons. The Ottomans brought to
33292-417: The summer preparing for this action, with the British assuming control of more of the front to release French troops for the attack. The bombardment, which had been carefully targeted by means of aerial photography , began on 22 September. The main French assault was launched on 25 September and, at first, made good progress in spite of surviving wire entanglements and machine gun posts. Rather than retreating,
33495-441: The summer, the French slowly advanced. With the development of the rolling barrage , the French recaptured Fort Vaux in November and by December 1916 they had pushed the Germans back 2.1 kilometres (1.3 mi) from Fort Douaumont, in the process rotating 42 divisions through the battle. The Battle of Verdun—also known as the 'Mincing Machine of Verdun' or 'Meuse Mill' —became a symbol of French determination and self-sacrifice. In
33698-406: The term "gunners" for the soldiers and sailors with the primary function of using artillery. The gunners and their guns are usually grouped in teams called either "crews" or "detachments". Several such crews and teams with other functions are combined into a unit of artillery, usually called a battery , although sometimes called a company. In gun detachments, each role is numbered, starting with "1"
33901-419: The terrible losses of 1 July, some divisions had managed to achieve their objectives with minimal casualties. In examining the reasons behind losses and achievements, once the British war economy produced sufficient equipment and weapons, the army made the platoon the basic tactical unit, similar to the French and German armies. At the time of the Somme, British senior commanders insisted that the company (120 men)
34104-414: The trenches in divisional strength until October. The incoming troops required training and equipment before they could join in the effort, and for several months American units were relegated to support efforts. Despite this, however, their presence provided a much-needed boost to entente morale, with the promise of further reinforcements that could tip the manpower balance towards the entente. In June,
34307-634: The use and effectiveness of Portuguese firearms above contemporary powers, making cannon the most essential element in the Portuguese arsenal. The three major classes of Portuguese artillery were anti-personnel guns with a high borelength (including: rebrodequim , berço , falconete , falcão , sacre , áspide , cão , serpentina and passavolante ); bastion guns which could batter fortifications ( camelete , leão , pelicano , basilisco , águia , camelo , roqueira , urso ); and howitzers that fired large stone cannonballs in an elevated arch, weighted up to 4000 pounds and could fire incendiary devices, such as
34510-497: The village and forest of Pinon were captured and the line of the Canal de l'Oise à l'Aisne was reached. In four days the French advanced 9.7 km (6 mi) and forced the Germans off the Chemin des Dames, back to the north bank of the Ailette valley by the night of 1/2 November. The French took 11,157 prisoners, 200 guns and 220 heavy mortars for c. 10,000 casualties from 23 to 26 October. Since mid-1915,
34713-548: The village of Kursi; the Russian commander was wounded and the brigade lost more than half of its troops but captured 635 prisoners and held the village. The attack on the right flank of the Sixth Army , which faced north between Oulches and Missy, took place from Oulches to Soupir and had less success than the Fifth Army; the II Colonial Corps advanced for 0.80 km (0.5 mi) in the first thirty minutes and
34916-416: The war by negotiated settlements, Germany could concentrate on Britain and fight a long war with the resources of Europe at its disposal. Hindenburg and Ludendorff continued to believe that Russia could be defeated by a series of battles which cumulatively would have a decisive effect, after which Germany could finish off France and Britain. Trench warfare in 1914, while not new, quickly improved and provided
35119-457: The war." On 20 November the British launched the first massed tank attack and the first attack using predicted artillery-fire (aiming artillery without firing the guns to obtain target data) at the Battle of Cambrai . The entente attacked with 324 tanks (with one-third held in reserve) and twelve divisions, advancing behind a hurricane bombardment, against two German divisions. The machines carried fascines on their fronts to bridge trenches and
35322-427: The way in which the past is understood. The Second Battle of the Aisne began on 16 April but the duration and extent of the battle have been interpreted differently. The ending of the battle is usually given as mid-May but Uffindell called this politically convenient, since it excluded the Battle of La Malmaison, in October, making it easier to blame Nivelle for a disaster. Uffindel wrote that the exclusion of La Malmaison
35525-492: The way that battles were fought. In the preceding decades, the English had even used a gunpowder-like weapon in military campaigns against the Scottish. However, at this time, the cannons used in battle were very small and not particularly powerful. Cannons were only useful for the defense of a castle , as demonstrated at Breteuil in 1356, when the besieged English used a cannon to destroy an attacking French assault tower. By
35728-580: The weapon of artillery is the projectile, not the equipment that fires it. The process of delivering fire onto the target is called gunnery. The actions involved in operating an artillery piece are collectively called "serving the gun" by the "detachment" or gun crew, constituting either direct or indirect artillery fire. The manner in which gunnery crews (or formations) are employed is called artillery support. At different periods in history, this may refer to weapons designed to be fired from ground-, sea-, and even air-based weapons platforms . Some armed forces use
35931-421: The weight in pounds. The projectiles themselves included solid balls or canister containing lead bullets or other material. These canister shots acted as massive shotguns, peppering the target with hundreds of projectiles at close range. The solid balls, known as round shot , was most effective when fired at shoulder-height across a flat, open area. The ball would tear through the ranks of the enemy or bounce along
36134-641: The welfare of French troops, which had a significant effect in restoring morale. Grand Quartier Général (GQG), the French general headquarters had predicted c. 10,000 casualties and French medical services were overwhelmed when the offensive began. In 1919, Pierrefeu gave French casualties from 16 to 25 April as 118,000, of whom 28,000 were killed, 5,000 died of wounds, 80,000 were wounded, 20,000 of whom were fit to return to their units by 30 April and 5,000 were taken prisoner. In 1920, Hayes wrote that British casualties were 160,000 and Russian casualties 5,183 men. In 1939, Wynne wrote that
36337-534: The west would go over to the strategic defensive for most of 1917, while the Central Powers would attack elsewhere. During the Somme battle and through the winter months, the Germans created a fortification behind the Noyon Salient that would be called the Hindenburg Line, using the defensive principles elaborated since the defensive battles of 1915, including the use of Eingreif divisions . This
36540-536: The west, the deepest advance by either side since 1914, but the success was short-lived. The unstoppable advance of the entente armies during the Hundred Days Offensive of 1918 caused a sudden collapse of the German armies and persuaded the German commanders that defeat was inevitable. The German government surrendered in the Armistice of 11 November 1918 , and the terms of peace were settled by
36743-573: The word "artillery" is often used to refer to individual devices, along with their accessories and fittings, although these assemblages are more properly called "equipment". However, there is no generally recognized generic term for a gun, howitzer, mortar, and so forth: the United States uses "artillery piece", but most English-speaking armies use "gun" and "mortar". The projectiles fired are typically either " shot " (if solid) or "shell" (if not solid). Historically, variants of solid shot including canister , chain shot and grapeshot were also used. "Shell"
36946-463: Was able to penetrate only a few hundred yards into the defences of the Condé-Riegel (Condé Switch Line). To the east of Vauxaillon at the north end of the Sixth Army, Mont des Singes was captured with the help of British heavy artillery but then lost to a German counter-attack. The Sixth Army operations took c. 3,500 prisoners but no break-through as achieved and at only one point had
37149-402: Was an attack on the German positions along the Chemin des Dames ridge, in the Second Battle of the Aisne and an eventual link with the British. The plan had been in development since December 1916 but the preparations were plagued by delays and information leaks. By April 1917, the plans were well known to the German army, which made extensive defensive preparations, by adding fortifications to
37352-421: Was artificial, since the attack was begun from the ground taken from April to May. General Franchet d'Espèrey called La Malmaison "the decisive phase of the Battle...that began on 16 April and ended on 2 November...". The offensive advanced the front line by 6–7 km (3.7–4.3 mi) on the front of the Sixth Army, which took 5,300 prisoners and a large amount of equipment. The operation had been planned as
37555-411: Was captured on 5 May. The Fourth Army attacks took 3,550 prisoners and 27 guns. German attacks on 27 May had temporary success before French counter-attacks recaptured the ground around Mont Haut; lack of troops had forced the Germans into piecemeal attacks instead of a simultaneous attack along all of the front. In 2015, Andrew Uffindell wrote that retrospective naming and dating of events can affect
37758-496: Was developed in Syracuse in 399 BC. Until the introduction of gunpowder into western warfare, artillery was dependent upon mechanical energy which not only severely limited the kinetic energy of the projectiles, it also required the construction of very large engines to accumulate sufficient energy. A 1st-century BC Roman catapult launching 6.55 kg (14.4 lb) stones achieved a kinetic energy of 16 kilojoules , compared to
37961-465: Was encountered. The Germans took Fort Douaumont and then reinforcements halted the German advance by 28 February. The Germans turned their focus to Le Mort Homme on the west bank of the Meuse which blocked the route to French artillery emplacements, from which the French fired across the river. After some of the most intense fighting of the campaign, the hill was taken by the Germans in late May. After
38164-423: Was intended to divert attention from offensives in the Eastern Front and disrupt Franco-British planning. After a two-day bombardment, the Germans released a lethal cloud of 168 long tons (171 t) of chlorine onto the battlefield. Though primarily a powerful irritant, it can asphyxiate in high concentrations or prolonged exposure. Being heavier than air, the gas crept across no man's land and drifted into
38367-426: Was intended to shorten the German front, freeing 10 divisions for other duties. This line of fortifications ran from Arras south to St Quentin and shortened the front by about 50 kilometres (30 mi). British long-range reconnaissance aircraft first spotted the construction of the Hindenburg Line in November 1916. The Hindenburg Line was built between 2 mi (3.2 km) and 30 mi (48 km) behind
38570-454: Was invented in the eastern Mediterranean region in the 12th century, with the earliest definite attestation in 1187. Early Chinese artillery had vase-like shapes. This includes the "long range awe inspiring" cannon dated from 1350 and found in the 14th century Ming dynasty treatise Huolongjing . With the development of better metallurgy techniques, later cannons abandoned the vase shape of early Chinese artillery. This change can be seen in
38773-416: Was launched on 14 August with the First and Second Armies attacking toward Sarrebourg-Morhange in Lorraine. In keeping with the Schlieffen Plan, the Germans withdrew slowly while inflicting severe losses upon the French. The French Third and Fourth Armies advanced toward the Saar and attempted to capture Saarburg, attacking Briey and Neufchateau but were repulsed. The French VII Corps captured Mulhouse after
38976-409: Was made more reliable by running telephone lines along steep slopes and deep valleys which were relatively free of French artillery-fire; wireless control stations had been set up during the winter to link aircraft to the guns. Verdun cost the French nearly 400,000 casualties and the conditions undermined morale, leading to a number of incidents of indiscipline. Although relatively minor, they reflected
39179-402: Was no longer possible for Germany to win the war by purely military means and on 18 November 1914 he called for a diplomatic solution. The Chancellor, Theobald von Bethmann Hollweg ; Generalfeldmarschall Paul von Hindenburg , commanding Ober Ost (Eastern Front high command); and his deputy, Erich Ludendorff , continued to believe that victory was achievable through decisive battles. During
39382-418: Was no time to establish artillery observation posts overlooking the Ailette valley, where French infantry had reached the ridge. Tunnels and caves under the ridge nullified much of the destructive power of the French artillery, which was also hampered by poor visibility and by German air superiority, which made French artillery-observation aircraft even less effective. The rear edge of the German battle zone along
39585-436: Was persistent and could contaminate an area for days, denying it to the British, an additional demoralising factor. The entente powers increased production of gas for chemical warfare but took until late 1918 to copy the Germans and begin using mustard gas. From 31 July to 10 November the Third Battle of Ypres included the First Battle of Passchendaele and culminated in the Second Battle of Passchendaele . The battle had
39788-422: Was removed from command, replaced by Pétain who immediately stopped the offensive. The French would go on the defensive for the following months to avoid high casualties and to restore confidence in the French High Command, while the British assumed greater responsibility. On 25 June the first US troops began to arrive in France, forming the American Expeditionary Force . However, the American units did not enter
39991-403: Was repeated two days later and caused a 3.1 mi (5 km) withdrawal of the Franco-British line but the opportunity had been lost. The success of this attack would not be repeated, as the entente countered by introducing gas masks and other countermeasures . An example of the success of these measures came a year later, on 27 April in the Gas attacks at Hulluch 40 km (25 mi) to
40194-401: Was repulsed and south of the river French infantry were forced back to their start-line. On the north bank of the Aisne the French attack was more successful, the 42nd and 69th divisions reached the German second position between the Aisne and the Miette, the advance north of Berry penetrating 4.0 km (2.5 mi). Russian troops participated in the attack and the 1st Russian Brigade captured
40397-417: Was the Battle of Liège , a siege that lasted from 5–16 August. Liège was well fortified and surprised the German Army under Bülow with its level of resistance. German heavy artillery was able to demolish the main forts within a few days. Following the fall of Liège, most of the Belgian field army retreated to Antwerp , leaving the garrison of Namur isolated, with the Belgian capital, Brussels , falling to
40600-411: Was the smallest unit of manoeuvre; less than a year later, the section of ten men would be so. In August 1916 the German leadership along the Western Front had changed as Falkenhayn resigned and was replaced by Hindenburg and Ludendorff. The new leaders soon recognised that the battles of Verdun and the Somme had depleted the offensive capabilities of the German Army. They decided that the German Army in
40803-434: Was then stopped. The XX Corps attack from Vendresse to the Oise–Aisne Canal had more success, the 153rd Division on the right flank reached the Chemin des Dames south of Courtecon after a second attack, managing an advance of 2.01 km (1.25 mi). The VI Corps advanced on its west of the Oise–Aisne Canal with its right wing but the left wing was held up. On the northern flank which faced east near Laffaux, I Colonial Corps
41006-501: Was used in Europe as a basic artillery manual. One of the most significant effects of artillery during this period was however somewhat more indirect—by easily reducing to rubble any medieval-type fortification or city wall (some which had stood since Roman times), it abolished millennia of siege-warfare strategies and styles of fortification building. This led, among other things, to a frenzy of new bastion -style fortifications to be built all over Europe and in its colonies, but also had
41209-423: Was viewed as its own service branch with the capability of dominating the battlefield. The success of the French artillery companies was at least in part due to the presence of specially trained artillery officers leading and coordinating during the chaos of battle. Napoleon , himself a former artillery officer, perfected the tactic of massed artillery batteries unleashed upon a critical point in his enemies' line as
