A terrific artillery attack was started by the Germans on the morning of April 24, 1915, and this was followed by a second rush of gas from their trenches. It rose in a cloud seven feet high and was making its attack on the British in two minutes after it started. It was thickest near the ground, being pumped from cylinders. And it worked with the same deadly effect. The Third Brigade, receiving its second attack of this sort before it had recovered from the first, retreated to the southwest of St. Julien, but soon after regained most of their lost position. The Second Brigade had to bend its left south. Colonel Lipsett's Eighth Battalion, however, held fast on the Grafenstafel ridge, remaining in their position two days in spite of the gas of which they got a plentiful supply. By noon of April 24, 1915, the Germans made an attack on the village of St. Julien and that part of the allied front to the east of the village. Thereupon the Third Brigade retreated about 700 yards to a new front south of the village and north of the hamlet of Fortuin. But what remained of the Thirteenth and Fourteenth Battalions was forced by circumstances to remain in the St. Julien line until late that night. Colonel Lipsett's Eighth Battalion at Grafenstafel, in spite of its left being unsupported, held its position which was of great importance to the British front. For, had that part of the front been lost, the Germans in an hour could have worked their way back of the Twenty-eighth Division and the entire eastern sector. In the meantime the French on the western section of the front made a counterattack from the canal with partial success; but were unable to drive the German troops from the sector entirely. The Teutons took Steenstraate; but their victory there was marred by the fact that the Belgian artillery smashed the bridge behind them. By this time the British reenforcements began to arrive in fairly large numbers. The Thirteenth Brigade of the Fifth Division was placed to the west of Geddes's Detachment, between the Pilkem road and the canal. Territorials who had arrived from England only three days before, the Durham and York Brigades of the Northumbrian Division, supported the Thirteenth Brigade. The Tenth Brigade of the Fourth Division were rushed to support the Third Brigade of Canadians who were south of St. Julien. Other British troops were sent to relieve the tense situation at Grafenstafel. An attempt to retake St. Julien was made early on Sunday morning, April 25, 1915, by General Hull's Tenth Brigade and two battalions of the Durham and York Brigade. The British worked their way to the few Canadians who had continued on the former front when the main British force had been driven back. There they were checked by the German machine gun fire. The British lost many men here and the efforts to save the day resulted in such a mixture of fighting units that there were fifteen battalions under General Hull, as well as the Canadian artillery.
