Driving south, the Germans inflicted defeats on the Allies along the Sambre at the Battles of Charleroi and Mons. Composed largely of reserve divisions, the Sixth Army came close to breaking but was reinforced by troops brought from Paris by taxicab on September 7. Leuven, (Louvain) was sacked by German troops and the Battle of Le Cateau was fought by the BEF and the First Army. Moltke, therefore, approved Klucks change of directionwhich meant the inevitable abandonment of the original wide sweep round the far side of Paris.

[7], On 26 August, German forces captured Valenciennes and began the Siege of Maubeuge (24 August 7 September). Still, some new weapons and technology used such as chemical warfare, flamethrowers and submarines caused great fear and chaos during World War I. [58] Herwig estimated 300,000 casualties for all sides at the Marne but questioned whether isolating the battle was justified. The first took place in September 1914, and the second in the summer of 1918. The German armies ceased their retreat after 40mi (65km) on a line north of the Aisne River, where they dug in on the heights and fought the First Battle of the Aisne. The first was Gen. Helmuth von Moltkes action in detaching seven regular divisions to invest Maubeuge and Givet and watch Antwerp, instead of using Landwehr (reserve) and Ersatz (replacement) troops as earlier intended. On an unsuspecting enemy, Britain unleashed its new secret weapon - the tank. . He decided to swing back his centre and left, with Verdun as the pivot, while drawing troops from the right and forming a fresh Sixth Army on his left to enable the retiring armies to return to the offensive. Using these two forces, he planned to attack on September 6. As the speed andflying capabilities of aircraft improved they evenbombed airfields, transportation networks and industrial facilities. South-east of Verdun, the Third Army was forced back to the west of Verdun by German attacks on the Meuse Heights, but maintained contact with Verdun and the Fourth Army to the west. Aerial photography of the front, 25 August 1916, Vickers .303 inchClass C medium machine gun, 1910. 1916 witnessed two of the longest and most notorious battles of the First World War. The First Battle of Ypres (20 October-22 November 1914) marked the end of open and mobile warfare on the Western Front. One of the few ways that tanks were effective during the war, was that they were capable of crossing barbed wire defences, although their tracks were still at risk of becoming entangled. They were the only army to wear any form of a camouflage uniform; the value of drab clothing was . [34] von Kluck and von Kuhl vigorously objected to this order as they believed their army was on the verge of breaking the Sixth Army. German airships achieved moderate success in long-range bombing operations, as Zeppelins could attain higher altitudes than the airplanes of the era. Further, the German command lost touch with the advancing armies, and movements at the front became disjointed. Tanks were developed by the British Army as a mechanical solution to the trench warfare stalemate. Both sides were faced with the prospect of costly siege warfare operations if they chose to continue an offensive strategy in France. [10] The Military governor of Paris, General Joseph Gallieni, was tasked with the defence of the city. While Paris was preparing for a siege, the Allies exploited the gap between the German First and Second armies. The British Army soon developed a range of gas helmets based on fabric bags and hoods that had been treated with anti-gas chemicals. The armoured vehicle would not truly come into its own until the doctrines of J.F.C. [61], On 10 September, Joffre ordered the French armies and the BEF to advance and for four days, the Armies on the left flank moved forward and gathered up German stragglers, wounded and equipment, opposed only by rearguards. [7], The French First and Second Armies had been pushed back, by attacks of the German 7th and 6th Armies between St. Di and Nancy. In this move against the French threat from the west, von Kluck ignored the Franco-British forces advancing from the south against his left flank and opened a 50-kilometre (30mi) gap in the German lines between the 1st Army and the 2nd Army on its left (east). Tuchman gave French casualties for August as 206,515 from Armes Franaises and Herwig gave French casualties for September as 213,445, also from Armes Franaises for a total of just under 420,000 in the first two months of the war. While the fighting prevented the Sixth Army from attacking the next day, it did open a 30-mile gap between the First and Second German Armies (Map). The delay in starting the advance meant that the Germans had time to scramble out of their dugouts, man their trenches and open a devastating machine-gun fire. Depth charges were first developed by the Royal Navy during World War I to combat German submarines. Europe Tanks and armored cars were used to protect soldiers as they travelled across rough, dangerous terrain. Machine guns were an exceptionally lethal addition to the battlefield in World War I. Between September 9 and 13, German forces broke off contact with the enemy and retreated north to this new line. On 5 September, the Battle of the Ourcq commenced when the Sixth Army advanced eastwards from Paris. In August 1914, the Germans mistook the speed andprecision of the British rifle fire for machine guns. The First Battle of the Marne was fought September 6-12, 1914, during World War I (1914-1918) and marked the limit of Germany's initial advance into France. Moltke ordered that Paris would now be bypassed and the sweep intended to encircle the city would now seek to entrap the French forces between Paris and Verdun. The attack was cancelled and the IX Reserve Corps was ordered to withdraw behind the right flank of the 1st Army. Though pushing back French and British forces, a gap opened between two armies on the German right wing. However, Hentsch reminded them he had the full power of the OHL behind him, and that 2nd Army was already in retreat. cannon The planning and conduct of war in 1914 were crucially influenced by the invention of new weapons and the improvement of existing types since the Franco-German War of 1870-71. The Fifth Army and the BEF had withdrawn south of the Oise, Serre, Aisne, and Ourq, pursued by the German 2nd Army on a line from Guise to Laon, Vailly, and Dormans and by the 1st Army from Montdidier, towards Compigne and then south-east towards Montmirail. These tanks were made for use on the Western Front because of the terrain's rough conditions. For the Germans, the result of the Battle of the Marne was a strategic but not a tactical defeat, and the German right wing was able to reknit and stand firmly on the line of the lower Aisne and the Chemin des Dames ridge, where trench warfare set in after assaults by the Allies in the latter half of September (First Battle of the Aisne). They alsomade the most of new technologieslike aircraft, sound ranging and flash spotting to locate and neutralise enemy artillery. The jaw formed by the German Sixth and Seventh armies merely broke its teeth on the defenses of the French eastern frontier. As these forces moved to isolate the German First Army, Kluck continued his attacks against Maunoury. Itconsisted of a metal tube fixed to an anti-recoil plate. In fact, the situation on the Western Front during the First World War was why the term trench warfare became synonymous with attrition, futile conflict, and stalemate. By the next day, French attacks north of the Aisne led Falkenhayn to order the 6th Army to repulse the French and secure the flank. World War I Timeline: 1914, The War Begins, M.S., Information and Library Science, Drexel University, B.A., History and Political Science, Pennsylvania State University. [21] The lack of coordination between von Kluck and Blow caused the gap to widen further. Artillery was the most destructive weapon on the Western Front. In the first days of September, the final decisions were made that were to directly create the circumstances for the Battle of the Marne. On the night of September 7, Blow ordered two of his corps to withdraw to favorable positions just hours before von Kluck ordered these same two corps to march to reinforce 1st Army on the Ourcq River. The Battle of Amiens in August 1918 and the subsequent 'Hundred Days' offensiveillustrated that the British had learned how to combine infantry assaults (men armed with rifles, grenades and machine guns) with gas, artillery, tanks and aircraft in a co-coordinated attack orall arms approach. Joffre first attempted to use diplomatic channels to convince the British government to apply pressure on Sir John French. There was a gap between the left of the Second Army and the right of the Third Army at Verdun, which faced north-west, on a line towards Revigny, against the Fifth Army advance west of the Meuse between Varennes and Sainte-Menehould. Fighting a series of holding actions, French forces, led by commander-in-chief General Joseph Joffre, fell back to a new position behind the Marne with the goal of holding Paris. [67] The French advance at the First Battle of Picardy (2226 September) met a German attack rather than an open flank and by the end of the Battle of Albert (2529 September), the Second Army had been reinforced to eight Corps but was still opposed by German forces at the Battle of Arras (14 October), rather than advancing around the German northern flank. Joffre ordered Entente troops to pursue, leading to the First Battle of the Aisne (see below). [66], From 17 September17 October the belligerents made reciprocal attempts to turn the northern flank of their opponent. In doing so, they exposed the right flank of the German advance to attack. [25] The Fifth Army by 8 September crossed the Petit Morin, which forced Blow to withdraw the right flank of the 2nd Army. The Allies frontal pursuit of the Germans from the Marne was already checked on the Aisne before Joffre, on September 17, seeing that Maunourys attempts to overlap the German flank were ineffectual, decided to form a fresh army under Gen. douard de Castelnau for a maneuver around and behind the German flank. The attack by Crown Prince Ruperts Sixth Army on the Grand-Couronn, covering Nancy, was a particularly expensive failure. One further factor must be mentioned, the most significant of all: the Germans had advanced so rapidly, outrunning their timetable, that their supplies had failed to keep pace. These guns were mounted to and used from a railway wagon that had been custom designed for the gun. The moves of the 7th and then the 6th Army from Alsace and Lorraine had been intended to secure German lines of communication through Belgium, where the Belgian army had sortied several times, during the period between the Great Retreat and the Battle of the Marne; in August, British marines had landed at Dunkirk. To the First World War index. They had a longer range, but needed a dozen men to operate them. Thesewere latermodified to carry smoke, incendiary devices, flares and anti-tank warheads, as well as high explosive. The Second Army had advanced from Marle on the Serre, across the Aisne and the Vesle, between Reims and Fismes to Montmort, north of the junction of the French 9th and 5th Armies at Szanne. [] That men will let themselves be killed where they stand, that is well-known and counted on in every plan of battle. Soldiers disliked the Mark 1 Grenade (above) because it was liable to detonateif knocked against something when being thrown. Mustard gas was fatal, but death could take up to five weeks. It was a relatively new weapon at the start of the war, but British and German forces soon realised its potential as a killing machine, especially when fired from a fixed defensive position.

On 12 August, the Battle of Haelen was fought by German and Belgian cavalry and infantry, resulting in a Belgian defensive success. [59] In 2010, Ian Sumner wrote that there were 12,733 British casualties, including 1,700 dead. First Battle of the Marne, (September 612, 1914), an offensive during World War I by the French army and the British Expeditionary Force (BEF) against the advancing Germans who had invaded Belgium and northeastern France and were within 30 miles (48 km) of Paris. Sandbox Learning is part of Sandbox & Co., a digital learning company. Becoming aware of this tactical error on September 3, Joffre began making plans for a counter-offensive the next day. Moltke is said to have reported to the Kaiser: "Your Majesty, we have lost the war." It was a possibility not studied in our war academy. During the Battle of Ypres, also in 1915, the Germans used chlorine gas for the first time. During the retreat, BEF commander Sir John French began to make contingency plans for a full retreat to the ports on the English Channel followed by an immediate British evacuation. Initially aircraft carried outartillery spotting and photographic reconnaissance. The following night, on 8 September, the Fifth Army launched a surprise attack against the 2nd Army, further widening the gap between the 1st and 2nd Armies. Moltke suffered a nervous breakdown upon hearing of the danger. Allied troops attacked the Germans' large Marne salient (i.e., a bulge protruding into the Allied lines), taking the Germans by surprise. A well-trained infantryman could fire 15 rounds a minute. Their direction of advance was across a region intersected by frequent rivers, and this handicap was intensified by a lack of initiative on the part of their chiefs. The first, highly coloured reports from the army commands in the Battles of the Frontiers had given the German Supreme Command the impression of a decisive victory. In the night of 6-7, two groups set off: the first, comprising 350 vehicles, departed at 10 PM, and another of 250 an hour later. When the British retraced their steps, it was the report of their columns advancing into the gap which led Blow to order the retreat of his Second Army on September 9. The Belgian army was invested at Antwerp in the National Redoubt and Belgian fortress troops continued the defence of the Lige forts. It was also the first large-scale use of motorised infantry in battle; a Marne taxicab is prominently displayed in the exhibit on the battle at the Muse de l'Arme at Les Invalides in Paris. The Germans introduced it, but it was later used by other forces. Let us know if you have suggestions to improve this article (requires login). The machine-gun was one of the deadliest weapons of the Western Front, causing thousands of casualties. Australians loading a 9.45 inch trench mortar on the Somme, August 1916, The Hawthorne Ridge mine detonating during the Battle of the Somme, 1916. Moreover, it carried him into the Amiens-Pronne area, where the first elements of the newly formed French Sixth Army were just detraining after their switch from Alsace. Tunnelling and mining operations were common on the Western Front. With the war stalled along the Aisne in Champagne, both armies began efforts to turn the other's flank in the west. Naval Operations in the Dardanelles Campaign. Pursued by the British and French, they defeated Allied attacks against this new position. . Joffres optimism might have been again misplaced but for German decisions. On 31 August, 1 September and 3 September, German aviators reported columns of French troops west of the 1st Army. Pushing through Belgium, the Germans were slowed by stubborn resistance which allowed the French and arriving British Expeditionary Force to form a defensive line. After the battle at the Marne River, the German and Allied troops realized old-fashioned battle was not the way to win this war. Told of the threat, Moltke suffered a nervous breakdown. It ranged in size from the French 75-mm field gun to the massive 420-mm Big Bertha and the 210-mm Paris Gun. [4], To the south, the French retook Mulhouse on 19 August and then withdrew. Joffre sacked General Charles Lanrezac, the commander of the Fifth Army and replaced him with I Corps commander Louis Franchet d'Esprey. The British Expeditionary Force, after concentrating near Maubeuge, France, had moved up to Mons, Belgium, on August 22, ready to advance farther into Belgium as part of the offensive of the Allied left wing. The Battle of Mulhouse (Battle of Alsace 7-10 August) was the first French offensive of World War I. He was concerned in particular with a gap which had opened between his Second and Third armies as a result of the latters having already turned south, from southwest, to help the Fourth Army, its neighbour on the other flank. This meant huge casualties and some of the deadliest battles in history, including Gallipoli, the Marne, Verdun and the Somme. As Joffre says in his memoirs: "it was he who made the Battle of the Marne possible".[46]. In fact, during World War I the word dogfight was first used to describe a battle between two opposing planes. Our editors update and regularly refine this enormous body of information to bring you reliable information.

He sent his intelligence officer, Oberstleutnant Richard Hentsch to visit the HQs. The First Battle of the Marne was fought between Germany and the allies of France and Britain. [57], In 2009, Herwig re-estimated the casualties for the battle. [47] The German retreat ended their hope of pushing the French beyond the VerdunMarneParis line and winning a quick victory. Le Cateau apparently convinced Kluck that the British force could be wiped from the slate, and Guise led Gen. Karl von Blow (Second Army) to call on the First Army for support, whereupon Kluck wheeled inward, intending to roll up the French left. [23], On 6 September, General Gallieni gathered about six hundred taxicabs at Les Invalides in central Paris to carry soldiers to the front at Nanteuil-le-Haudouin, fifty kilometres away. By 10 September the Germans had received orders to stop attacking and withdrawal towards the frontier became general. For his failure, he was replaced as Chief of the General Staff on September 14 by Erich von Falkenhayn. It had a maximum range of 2,280 metres, but an effective killing range of 550. [26] The Germans had still hoped to smash the Sixth Army between 6 and 8 September, but the Sixth Army was reinforced on the night of 7/8 September by 10,000 French reserve infantry ferried from Paris. War: The First World War also known as 'The Great War'. The age of the battleship reached its apotheosis in World War I, as even the Dreadnought, the archetypal big-gun ship, found itself outgunned. While modern weaponshad helped create this problem, generals hoped thatthey would also assistthe army in fighting their way out of it. [60] Sumner cites the same overall casualty figure for the French for September as Herwig from Armes Franaises, which includes the losses at the battle of the Aisne, as 213,445 but provides a further breakdown: 18,073 killed, 111,963 wounded and 83,409 missing. Thought the presentation & interpretation made the subject accessible". At first, these were simple, shallow pits, but quickly they became deeper, more elaborate trenches. On 5 September German troops reached Claye-Souilly, 15 kilometres (10mi) from Paris, captured Reims, and withdrew from Lille, and the BEF ended its retreat from Mons. Frontal attacks by the Ninth, Fifth, and Sixth Armies were repulsed from 1516 September. The Belgian government withdrew from Brussels on 18 August. In fact, during World War I, an estimated 1.3 million had died from the use of chemical weapons. [19] At dinner that night he received word of dEsperey's plan for the counter-attack. For commanders, the greatest tacticalproblemwas to get troops safely across the fire-swept divide between the trenchesto penetrate enemydefences. By the next day, both the German First and Second Armies were being threatened with encirclement and destruction. The attempt at a partial envelopment, pivoting on Verdun, had already failed. Chlorine gas caused suffocation after the victim experiences chest pains and burning in the throat. It was cheap, easy to erect and ensnared enemies. However, chlorine gas proved tricky to use. Armies were forced to adapt their tactics and pursue new technologies as a way of breaking the deadlock. Airplanes and submarines were used for the first time, initially to locate the enemy. However, flamethrowers were effective, causing lots of havoc on the battlefield. Planes also made their debut in the First World War. The temporary advantage which the German First Army had gained over Maunoury was thereby nullified, and it fell back the same day. Exploiting this, the Allies attacked into the gap and threatened to encircle the German First and Second Armies. [14] D'Esperey became one of the originators of the Entente plan during the Battle of the Marne. The man with the goggles belongs to the Intelligence Corps. Both resulted in hundreds of thousands of casualties for both the Allies and Germans on the Western Front. Their size and mobility offered advantages over conventional artillery as they could be fired from within the safety of a trench. Hickman, Kennedy. On September 8 Gen. Louis Franchet dEspereys Fifth Army made a surprise night attack on the German Second Army and widened the gap. We know anyhow that with a prescience greater in political than in military affairs, he wrote to his wife on the night of the 9th, "Things have not gone well. By prematurely wheeling his forces before Paris had been reached, Kluck exposed the German right to a counterenvelopment. But they soon grew more substantial. The German idea, known as the Schlieffen Plan after the general who first came up with it in 1905, was to launch its armies in a giant right hook through neutral Belgium and northern France to outflank and destroy the French army and then capture Paris. Here are the facts and trivia that people are buzzing about.
