Roll call of the survivors on 25 April 1915 after the gas attack. three officers and 316 men answered the roll from a pre-battle strength of 980.
On 22 April 1915, the German 26th Reserve Corps launched the opening attack of the battle of 2nd Ypres against the French 87th Territorial and 45th Algerian Divisions on the immediate left flank of the 1st Canadian Division. The assault was preceded by the first mass use of poison gas in modern warfare and the effect was devastating. By midnight, the Germans had penetrated deep into the French sector and were threatening the now exposed Canadian left flank.
The British/Canadian front line had effectively become a pronounced salient. At the apex of that salient, the positions occupied by the 13th and 15th Battalions of the Canadian 3rd Infantry Brigade, were under threat of enfilade fire and encirclement from their rear. In an attempt to plug the open left flank on the night of 23 April, hasty counterattacks were conducted against the advancing Germans at Kitcheners’ Wood by the 10th and 16th Battalions. Units rushed to form a new hasty defence line all along the open flank from the Canadian front line at the apex all the way back to the Yser Canal.

The area on the exposed left between St Julian and the front-line positions of the 13th and 15th Battalions was under the most serious and immediate threat. Therefore, to plug that hole, the 13th Battalion line folded back on itself to form a right angle (a manoeuver called “refusing the flank”) and elements of the 7th Battalion and the British 2/East Kent Battalion (The Buffs) were moved in on the 13th’s left. The 15th Battalion was now literally at the very apex of the Canadian salient and being subjected to artillery and small arms fire from the front, left flank and rear.
At approximately 4am on the morning of the 24th, the Germans launched a second gas attack which hit the apex of the line descending most heavily on No. 1 and part of No. 3 Company on the right of the 15th’s line as well as part of the 8th Battalion’s line to their right. No. 1 Company was effectively annihilated by the combined effects of the gas, artillery and the follow-on assaulting German infantry which penetrated that portion of the 15th’s line. Of all the Canadian units engaged that day, the 15th Battalion was the only one without any artillery support as their supporting battery had mistakenly pulled back out of range.
In terms of what followed the collapse of No. 1 Company’s position, it is unfortunately reasonably simple to explain tactically. As the surviving elements of No. 3 Company in the centre and No. 4 Company on the right were effectively pinned in position by fire from the front and enfilade from the exposed left, the Germans rolled-up the line from right to left one platoon at time. To be sure, there was desperate fighting and Major Marshall’s close support element at Death Mill delayed the enemy penetration into the rear of the front-line positions somewhat but in the end, as the apex was gradually lost, the survivors fell back as best they could to reserve positions hastily formed along Gravenstafel ridge by other Canadian units rushed into place.
No. 2 Company, which had been left in reserve at St Julian, had become part of a combined force defending the town and the new left flank against the German advance that penetrated the French line on the 21st. With the front line at the apex collapsing and German pressure on the left continuing, the sub-units of the St Julien “garrison” were overrun and surrendered on April 25th.
When the 15th Battalion moved into the forward line to relieve the 16th Battalion on 20 April 20, it had a field strength of approximately 900 all ranks. When the surviving elements of the battalion regrouped at Wieltje on 25 April, approximately 647 had become casualties – 233 dead, of which 187 were MIA, 248 PoWs and the remainder wounded with many of those eventually dying. There is a well-known period photograph referred to as “The Roll Call” that shows survivors lined up in the battalion’s transport lines with an NCO calling the roll. Those who answered that roll call totalled three Officers and 150 Other Ranks. Battalion leadership, both Officers and Senior NCOs, was decimated – the battalion, in effect, had been destroyed. As the Official History of The Canadian Forces in The Great War 1914-1918 states: “No other Canadian battalion, and few British battalions, ever suffered so heavily in so short a time.” The battalion would be quickly rebuilt with hundreds of reinforcements from CEF units in the UK. It would go on to take part in every major campaign and battle in which the Canadian Corps was involved for the duration of the war winning 20 Battle Honours in process. Ypres had been a successful defence but a costly ‘baptism of fire.’
