Template:Short description Template:For Template:Use British English Template:Use dmy dates Template:Infobox military conflict The Second Battle of Ypres was fought from 22 April – 25 May 1915, during the First World War, for control of the tactically valuable high ground to the east and the south of the Flemish town of Ypres, in western Belgium. The First Battle of Ypres had been fought the previous autumn. The Second Battle of Ypres was the occasion of the first mass use by Germany of poison gas on the Western Front.

Background

The German chemist Walther Nernst was a volunteer driver in 1914 and proposed to Colonel Max Bauer, the German general staff officer responsible for liaison with scientists, that they could empty the opposing trenches by a surprise attack with tear gas. Observing a field test of this idea, the chemist Fritz Haber instead proposed using heavier-than-air chlorine gas.<ref name="HistoryCollection">Template:Cite web</ref>

The professional head of the German Army, General Erich von Falkenhayn, agreed to try the new weapon with the 4th Army.Template:Sfn Falkenhayn wanted to use the gas to cover the transfer of units to the Eastern Front to assist the Austro-Hungarian Army against the Imperial Russian Army after its losses in 1914.Template:Sfn Gas could not be released directly because the valves would freeze; liquid chlorine from cylinders would be syphoned for it to vaporise and be carried by a breeze to the British and French lines. German troops carried 5,730 gas cylinders, the largest weighing Template:Cvt, into the front line for the release.

The installation was supervised by Haber, Otto Hahn, James Franck and Gustav Hertz. Cylinders were breached by shell fire on two occasions and the second time, three men were killed and fifty wounded. Some of the Germans were protected by miners' oxygen breathing apparatus. The Ypres Salient was selected for the attack, the front line followed the canal and bulged eastward around the town. North of the salient, the Belgian army held the line of the Yser, and the north end of the salient was held by two French divisions.Template:Sfn The eastern bulge of the salient was defended by the 1st Canadian Division and two British divisions. The II Corps and V Corps of the Second Army comprised the 1st Cavalry Division, 2nd Cavalry Division and 3rd Cavalry Division, as well as the 4th Division, 27th Division, 28th Division, 50th (Northumbrian) Division, 3rd (Lahore) Division and the 1st Canadian Division.Template:Sfn

In A record of the Engagements.... (1923), E. A. James used The Official Names of the Battles and Other Engagements.... (1921) to provide a summary of each engagement and the formations involved.Template:Efn In the Battles of Ypres, 1915, there were four engagements involving the Second Army from 22 April to 25 May.Template:Sfn

On 22 April 1915 at about Template:Nowrap, the 4th Army released Template:Cvt of chlorine gas on a Template:Convert front, between the hamlets of LangemarkTemplate:Efn and GravenstafelTemplate:Efn This sector of the Allied line was held by the 87th Territorial Division (comprising older reservists from 10th Military District, based in Rennes), alongside the 45th Infantry Division (France) (comprising troops from the (North African) 19th Military District).Template:SfnTemplate:Sfn The French troops in the path of the gas cloud suffered Template:Nowrap with Template:Nowrap fatalities. Troops fled the gas cloud,

A Template:Cvt gap in the French front was left undefended. German infantry followed well behind the cloud, breathing through cotton pads soaked with sodium thiosulfate solution and occupied the villages of Langemark and Pilckem, where they dug in, even though they might have occupied Ypres almost unopposed.Template:Sfn The Germans had captured 2,000 prisoners and 51 guns. Canadian troops defending the southern flank of the break-in identified chlorine because it smelled like their drinking water. The Germans released more chlorine gas at them the following day. Casualties were especially severe for the 13th Battalion (Royal Highlanders of Canada) of the Canadian Expeditionary Force (CEF), which was enveloped on three sides and had overextended its left flank after the Algerians of the 45th Division broke.Template:Sfn

In an action at Kitcheners' Wood, the 10th Battalion of the 2nd Canadian Brigade was ordered to counter-attack in the gap created by the gas attack. They formed up after Template:Nowrap on 22 April, with the 16th Battalion (Canadian Scottish) of the 3rd Brigade arriving to support the advance. Both battalions attacked with over Template:Nowrap in waves of two companies each, at Template:Nowrap Without reconnaissance, the battalions ran into obstacles halfway to their objective. Engaged by small-arms fire from the wood, they began an impromptu bayonet charge. The attack cleared the former oak plantation of Germans at a 75 per cent casualty rate.Template:Sfn

Template:Blockquote

The Germans reported that they treated 200 gas casualties, 12 of whom died. The Allies reported 5,000 killed and 15,000 wounded.Template:Sfn Within days the British were advised by John Scott Haldane to counter the effects of the gas by urinating into a cloth and breathing through it. Both sides set about developing more effective gas masks.

Template:AnchorBattle of St. Julien (24 April – 5 May)

The village of St. Julien (now Sint-Juliaan; Template:Coord) was in the rear of the 1st Canadian Division until the poison-gas attack of 22 April, when it became the front line. Some of the first fighting in the village involved the stand of Lance Corporal Frederick Fisher of the 13th Battalion CEF's machine-gun detachment; Fisher went out twice with a handful of men and a Colt machine gun, preventing advancing German troops from passing through St. Julien into the rear of the Canadian front line. He was killed the following day.Template:Sfn

On the morning of 24 April, the Germans released another gas cloud towards the re-formed Canadian line just west of St. Julien. Word was passed to the troops to urinate on their handkerchiefs and place them over their nose and mouth.Template:SfnTemplate:Efn The countermeasures were insufficient and German troops took the village.Template:Sfn The next day the York and Durham brigades of the Northumbrian Division counter-attacked, failing to secure their objectives but establishing a new line closer to the village.Template:Sfn On 26 April the 4th, 6th and 7th Battalions of the Northumberland Brigade, the first Territorial brigade to go into action, attacked and gained a foothold in the village but were forced back, having suffered Template:NowrapTemplate:Sfn Despite hundreds of casualties, the 2nd Battalion Royal Dublin Fusiliers participated without respite in the battles at Frezenberg and Bellewaarde. On 24 April the battalion, subjected to a German gas attack near St. Julien, was nearly annihilated.

The German Army first used chlorine-gas cylinders in April 1915 against the French Army at Ypres, when yellow-green clouds drifted towards the Allied trenches.Template:Efn The gas had a distinctive odour, resembling pineapple and pepper. The French officers, assuming at first that the German infantry were advancing behind a smoke screen, alerted the troops. When the gas reached the front Allied trenches, soldiers began to complain of chest pains and a burning sensation in the throat.Template:Citation needed

George Nasmith, the head of the field laboratory for the Canadian Expeditionary Force, advised a Canadian field ambulance officer to pass the order to use urine to counteract the gas.

Captain Francis Scrimger of the 2nd Canadian Field Ambulance may have passed the order to use urine to counteract the gas, on the advice of Lieutenant-Colonel George Nasmith. Soldiers realised they were being gassed and many ran as fast as they could. An hour after the attack began, there was a Template:Convert gap in the Allied line.Template:Sfn Fearing the chlorine, few German soldiers moved forward and the delay enabled Canadian and British troops to retake the position before the Germans could exploit the gap.Template:Sfn

After the first German chlorine-gas attacks, Allied troops were supplied with masks of cotton pads soaked in urine; it had been discovered that the urea in the pad neutralised the chlorine. The pads were held over the face until the gas dispersed. Other soldiers preferred to use a handkerchief, sock or flannel body-belt, dampened with a sodium bicarbonate solution and tied across the mouth and nose, until the gas passed. Soldiers found it difficult to fight like this and attempts were made to develop a better means of protection against gas attacks.Template:Sfn By July 1915, soldiers received efficient gas masks and anti-asphyxiation respirators. Private W. Hay of the Royal Scots arrived in Ypres just after the chlorine-gas attack on 22 April 1915:Template:Sfn

The Germans moved field artillery forward and assembled three corps opposite the 27th Division and 28th Division on the Frezenberg ridge (Template:Coord).Template:Sfn The German attack began on 8 May with a bombardment of the 83rd Brigade in trenches on the forward slope of the ridge but the first and second infantry assaults were repelled by the survivors. The third German assault of the morning pushed the defenders back. Although the neighbouring 80th Brigade repulsed the attack, the 84th Brigade was pushed back; this left a Template:Cvt gap in the line. The Germans were prevented from advancing further by the counter-attacks of Princess Patricia's Canadian Light Infantry (PPCLI) and a night move by the 10th Brigade. The PPCLI success was costly, their 700 men were reduced to 150, who were in no shape to fight.Template:SfnTemplate:Efn

Template:AnchorBattle of Bellewaarde (24–25 May)

On 24 May the Germans released a gas attack that hit Shell Trap Farm and to the area around the north-west, which was affected the most by the attack. A report of the event by Captain Thomas Leahy, of the 2nd Royal Dublin Fusiliers, shows that their C.O. Lieutenant Colonel Arthur Loveband suspected a gas attack and had warned all company officers. Later the Germans threw up red lights over their trench, which would signal a gas release.<ref name="jeremybanning.co.uk">Template:Cite web</ref>

Template:Blockquote

German forces managed to advance and occupy the British line to north and left of the Battalion. The Battalion was now under heavy fire from the German forces. But with shellfire and the aid from the 9th Argyll and Sutherland Highlanders they managed to hold their trenches to the end.<ref name="jeremybanning.co.uk"/>

Aftermath

Analysis

By the end of the battle, British forces had withdrawn to a new line 3 miles closer to Ypres, thereby resulting in a compression of its surrounding salient.Template:Sfn The city, bombarded by artillery fire, was demolished. Although poison gas had been used on the Eastern Front, it surprised the Allies and about 7,000 gas casualties were transported in field ambulances and treated in casualty clearing stations. In May and June, 350 British deaths were recorded from gas poisoning.Template:Sfn Both sides developed gas weapons and counter-measures, which changed the nature of gas warfare; the French and British used gas at the Battle of Loos in late September.Template:Sfn Gas protection was somewhat improved with the issue of improvised respirators made from cotton waste pads impregnated with sodium hyposulphite, sodium bicarbonate and glycerin. The respirators made little difference, however, due to lack of training and the use of local contraptions and poorly made items imported from Britain. The "P helmet" (or "Tube Helmet") soaked in sodium phenate was issued by December 1915, and the PH helmet (effective against phosgene) was issued in early 1916.Template:Sfn Template:Multiple image Although many French troops ran for their lives, others stood their ground and waited for the cloud to pass. Field Marshal Sir John French, Commander-in-Chief of the British Expeditionary Force, wrote,

Template:Blockquote

The Canadian Division mounted an effective defence but had 5,975 casualties by its withdrawal on 3 May. The division was unprepared for the warfare prevailing on the Western Front, where linear tactics were ineffective against attackers armed with magazine rifles and machine guns. The Canadian field artillery had been effective but the deficiencies of the Ross rifle worsened the tactical difficulties. The Canadian Division received several thousand replacements shortly after the battle.Template:Sfn At Second Ypres, the smallest tactical unit in the infantry was a company; by 1917 it would be the section. The Canadians were employed offensively later in 1915 but not successfully. The battle was the beginning of a long period of analysis and experiment to improve the effectiveness of Canadian infantry weapons, artillery and liaison between infantry and artillery.Template:SfnTemplate:Efn

Casualties

After the war, German casualties from 21 April to 30 May were recorded as 34,933 by the official historians of the Template:Lang. In the British Official History, J. E. Edmonds and G. C. Wynne recorded British losses of 59,275 casualties, the French about 18,000 casualties on 22 April and another 3,973 from Template:NowrapTemplate:Sfn Canadian casualties from 22 April to 3 May were 5,975, of whom about 1,000 men were killed. The worst day was 24 April, when Template:Nowrap were suffered during infantry attacks, artillery bombardments and gas discharges.Template:Sfn In 2003, Clayton wrote that thousands of men of the 45th and 87th divisions ran from the gas but that the number of casualties was low. The Germans overran both divisions' artillery but the survivors rallied and held a new line further back.Template:Sfn In 2010, Humphries and Maker, in their translated edition of Der Weltkrieg recorded that by 9 May, there had been more than 35,000 German casualties, 59,275 British between 22 April and 31 May and very many French casualties, 18,000 on 22 April alone.Template:Sfn In 2012, Sheldon gave similar figures and in 2014, Greenhalgh wrote that French casualties had been exaggerated by propaganda against German "frightfulness" and that in 1998, Olivier Lepick had estimated that Template:Nowrap were killed by gas in April out of Template:Nowrap casualties.Template:Sfnm

Subsequent operations

The First Attack on Bellewaarde was conducted by the 3rd Division of V Corps on 16 June 1915 and the Second Attack on Bellewaarde, a larger operation, was conducted from Template:Nowrap by the 3rd Division of V Corps and the 14th Division of VI Corps. The Battle of Mont Sorrel Template:Nowrap took place south of Ypres with the 20th Division (XIV Corps) and the 1st, 2nd and 3rd Canadian divisions of the Canadian Corps.Template:Sfn The Third Battle of Ypres, also known as the Battle of Passchendaele, was fought from 31 July to 10 November 1917.Template:Sfn
