The left flank of the Canadian Division was thus left dangerously exposed to serious attack in flank, and there appeared to be a prospect of their being overwhelmed and of a successful attempt by the Germans to cut off the British troops occupying the salient to the East.
In spite of the danger to which they were exposed the Canadians held their ground with a magnificent display of tenacity and courage; and it is not too much to say that the bearing and conduct of these splendid troops averted a disaster which might have been attended with the most serious consequences.
They were supported with great promptitude by the reserves of the divisions holding the salient and by a brigade which had been resting in billets.
Throughout the night the enemy's attacks were repulsed, effective counter-attacks were delivered, and at length touch was gained with the French right, and a new line was formed.
The 2d London Heavy Battery, which had been attached to the Canadian Division, was posted behind the right of the French Division, and, being involved in their retreat, fell into the enemy's hands. It was recaptured by the Canadians in their counter-attack, but the guns could not be withdrawn before the Canadians were again driven back.
During the night I directed the Cavalry Corps and the Northumbrian Division, which was then in general reserve, to move to the west of Ypres, and placed these troops at the disposal of the General Officer Commanding the Second Army. I also directed other reserve troops from the 3d Corps and the First Army to be held in readiness to meet eventualities.
In the confusion of the gas and smoke the Germans succeeded in capturing the bridge at Steenstraate and some works south of Lizerne, all of which were in occupation by the French.
The enemy having thus established himself to the west of the Ypres Canal, I was somewhat apprehensive of his succeeding in driving a wedge between the French and Belgian troops at this point. I directed, therefore, that some of the reinforcements sent north should be used to support and assist General Putz, should he find difficulty in preventing any further advance of the Germans west of the canal.
At about ten o'clock on the morning of the 23d connection was finally ensured between the left of the Canadian Division and the French right, about 800 yards east of the canal; but as this entailed the maintenance by the British troops of a much longer line than that which they had held before the attack commenced on the previous night, there were no reserves available for counter-attack until reinforcements, which were ordered up from the Second Army, were able to deploy to the east of Ypres.
Early on the morning of the 23d I went to see General Foch, and from him I received a detailed account of what had happened, as reported by General Putz. General Foch informed me that it was his intention to make good the original line and regain the trenches which the French Division had lost. He expressed the desire that I should maintain my present line, assuring me that the original position would be re-established in a few days. General Foch further informed me that he had ordered up large French reinforcements, which were now on their way, and that troops from the North had already arrived to reinforce General Putz.
