From the Regimental History,page 48 "Simultaneously with the opening of the barrage the two mines under the Boche right front were exploded, and the 72nd moved forward to the attack, as promptly and with angry violence, in answer to frantic S. O. S. rockets, the German protective barrage came down on No Man's Land and on the trenches which the Battalion had just left, being particularly heavy in the vicinity of Montreal Crater, which was the left centre of the Battalion's front."
