Two reserve battalions had been brought up in hot haste from Ypres to strengthen the left of the line. These were the 16th (Canadian Scottish) and the 10th Canadians. Their advance was directed against the wood to the west of St. Julien, in which lay our four guns which, as already described, had fallen into the hands of the Germans. Advancing about midnight by the light of the moon, these two brave regiments, under Colonels Leckie and Boyle, rushed at the wood which the Germans had already {52} entrenched and carried it at the point of the bayonet after a furious hand-to-hand struggle. Following at the heels of the flying Germans, they drove them ever deeper into the recesses of the wood, where there loomed up under the trees the huge bulk of the captured guns. For a time they were once again in British hands, but there was no possible means of removing them, so that the Canadians had to be content with satisfying themselves that they were unserviceable. For some time the Canadians held the whole of the wood, but Colonel Leckie, who was in command, found that there were Germans on each side of him and no supports. It was clear, since he was already a thousand yards behind the German line, that he would be cut off in the morning. With quick decision he withdrew unmolested through the wood, and occupied the German trenches at the south end of it. Colonel Boyle lost his life in this very gallant advance, which may truly be said to have saved the situation, since it engaged the German attention and gave time for reinforcements to arrive. The immediate pressing necessity was to give the French time to re-form, and to make some sort of line between the Canadian left and the French right. As early as half-past two in the morning, while the two Canadian regiments were struggling in the wood of St. Julien, the First Cavalry Division were showing once again the value of a mobile reserve. De Lisle's horsemen were despatched at full speed to get across the Canal, so as to act as a support and an immediate reserve for the French. The 2nd East Yorks from the Twenty-eighth Division was also sent on the same errand. [Sidenote: April 23.]
