The German artillery fire greatly exceeded the British in volume. Nevertheless the British forces were in the more comfortable position. They had comparatively little to do except wait until they were needed, which would be when their artillery had completed the preparation for the inevitable charge. On the other hand the German soldier had a nerve-racking part to play. He knew from the preparation that an attack in force was about to be made; but he did not know when it would occur nor where. Hence it was necessary for him to be constantly on the alert. Many of the Germans were under arms at all hours of the day and night. In fact few of them on that part of their line got any real rest during the week in which the bombardment continued. The section between the two lines of trenches was illuminated at night, and the cannonade kept up so that there was no opportunity for the Germans to repair the havoc made by the British shells. The suspense was terminated on the evening of June 15, 1915, by an additional flight of projectiles from the British guns. Every piece of British ordnance on that part of the line was worked at top speed. The Germans, knowing that this immediately preceded an infantry charge, used their artillery to stop it. But the British charge formed in their trenches, with the Canadians on their right. In addition to the shrapnel the Germans made breaks in the lines of their foes by the use of machine guns, but the breaks were quickly filled. On some parts of the front the British and Canadians were successful and reached the trenches. In all the captured trenches extended from Rue du Bois to Rue d'Ouvert. In the meantime those Canadians who had been directed against Stony Mountain and Dorchester were doing heroic work. The First Company of the Ontario Regiment charged through the debris of the mine explosion, only to run into the deadly hail sent at them by the machine guns. But the Canadians were determined to complete their task, and they took Dorchester and the connecting trench. The fire was too heavy for them to reach Stony Mountain. A group of bombers made a dash forward, but were shot down before they could get near enough to use their weapons.
