HOWEVER......
In the gas attack in the St.-Julien sector, two men from A Company, 8th Battalion, told me that they both fired their Rosses until they were too hot to touch to reload.
They then acquired Rosses from casualties and continued the fight until THOSE rifles were too hot to touch, then went back to their own now-cooled rifles.
The men were Private Alex McBain and Lance-Corporal Robert Courtice.
Lance-Corporal Courtice denied that they had ANY problems with their rifles.
Private McBain was most vehement in his denial of problems with the Ross, very nearly becoming violent when I suggested that there might have been a problem. "We had NO problems with the Ross Rifle! It's all lies!"
These men could not have confused that battle with any other because, for each man, Second Ypres was their ONLY big fight. Private McBain was shot during the battle and invalided out when it was over, then sent home. Lance-Corporal Courtice was blown up by a 90-pounder (15cm) at Givenchy, a day before the attack.
It should be noted that A Company, 8th Battalion was the Reserve Company; they were the ones who went up through the gas and plugged the Line when the French Colonial troops (who had no protection against Gas) broke and ran. This was the "schwerpunkt" of the German attack, with several German DIVISIONS scheduled to pour through the gap. German troops were carrying the Gew 98 (Mauser) rifle.
The 120 men of A Company, 8th Battalion (the Little Black Devils) were in a position to LOSE THE WAR that day, but they did not.
The ensuing battle was a pure rifle engagement at very close ranges ("Too close to miss," said L/Cpl Courtice).
The Ross won.
Further deponent sayeth not.
