22 April 1915: 17.00 - 24.00
Battle of Gravenstafel Ridge

The Ypres Salient: Location of the German Gas Attack on 22 April 1915Summary: 22 April 5pm to midnight

Most of the French territorial and Algerian troops not immediately asphyxiated by the poisonous gas retired from the front line in confusion. The German infantry, following on behind the gas cloud at 5.15pm, successfully broke through the Allied front line.

Within half an hour of the attack the German 52. Reserve Division in the centre of the attacking front had covered 3 to 4 kilometres of French-held ground and had reached its first objective - the high ground of Pilckem Ridge - by the village of Pilckem.

Map: Extent of the German advance by midnight, 22 AprilThe German 45. and 46. Reserve Divisions reached the Yser Canal and established bridgeheads on the west bank at Steenstraat and the lock at Het Sas (south of Lizerne). A dangerous gap in the Allied front line was created as a result of the French withdrawal. The way to Ypres was open.

The left wing of the British Second Army sector (at St. Julien) was not directly attacked. However, as a result of the French withdrawing on their immediate left, the rear of 13th Battalion of 1st Canadian Division was in danger of being exposed. This battalion, together with some French troops, formed a flank on the left wing of the British sector along the St. Julien-Poelcappelle road. They put up a stubborn defence to hinder the progress of the German 51. Reserve Division on the left wing of the German attack.

A French counter-attack was launched at 8pm from Boesinghe towards Pilckem but it made little progress. A counter-attack was prepared by the Canadian 3rd Infantry Brigade for 11.30pm. Its launch was postponed until midnight and the attack took place in the early hours of the morning of 23 April.

By midnight on 22 April the Allies had lost a significant amount of ground in the north part of the Ypres Salient. At about 8.30pm the German infantry stopped its advance and held an advantageous position on the high ground of Pilckem Ridge. German artillery then subjected Ypres and its surrounding area to a heavy artillery bombardment during the late evening. The intention was to hinder the Allies in their attempt to bring reinforcements into the area overnight.

Name of the Battle

Map: The ground gained by the German Army (pink) by the end of 22 April. Gravenstafel Ridge can be seen in the top right of the map.The Battles Nomenclature Committee gave the name of the Battle of Gravenstafel Ridge to the first battle of The Second Battle of Ypres fought from 22 - 23 April. The British Official History comments that there does not seem to be a reason for connecting this first battle with the Gravenstafel Ridge. The ridge was an east-west spur, on which the village of Gravenstafel was situated, running off the high ground of the ridge to the east of Zonnebeke. The German attack and the British counter-attacks actually took place farther to the west in the region of Keerselaere and west of St. Julien.
