This action earned the battalion, and other units, recognition from Sir Douglas Haig in his first despatch for "good work in carrying out... local attacks and raids". On 27 March 1916, following an artillery bombardment, combined with the detonation of mines beneath the German trenches, the British 5th Corps attacked the St Eloi salient. On the night of 3–4 April, the Canadian Corps relieved the British, with the 6th Canadian Brigade taking up positions in front of the craters created by the detonations. The last letter from Ross is dated 4 April 1916. He reports: "there's lots of fighting where we are at present, and just now we are in the German trenches, so have a busy time... I'd like to see you all again..." For the next two days, the Canadian front line was under almost continuous bombardment. The 27th Battalion fared particularly badly, and on the night of 5–6 April, the 29th began relieving them, slowed down by the mud, extra equipment and a congestion of troops. The corporal of Ross's section reported his death: "On the morning of 6 April we were serving together in the trenches. While attending devotedly and most courageously, under heavy artillery fire, to our wounded men, he was himself hit, and falling over a man he was dressing, died instantly. Quite reckless as regarding his own life, he exposed it, and gave it to save, as his quick attention undoubtedly did, the lives of a great number of our men." It transpired later that Ross was already wounded before he was himself killed. Ross is buried at the Ridge Wood Military Cemetery (Grave IR9), West Flanders, Belgium.
