At length February 17th arrived, and, in the evening, the raiders began to move up to their positions. All were assembled, according to plan, before zero. Apart from an enemy searchlight, which swept No Man’s Land during the assembly but did not reveal the men to the Germans, the preliminaries passed off without incident. Just before the barrage opened, Sec.-Lieut. W. L. Hirst advanced with his torpedo party. The torpedo was a cumbersome affair, twenty-two feet long, which required three men to carry it. As the party moved forward it laid out a tape, to show the direction to the raiders. The barrage had now opened, the enemy was thoroughly aroused, and the flares which he was firing considerably helped the party, as it hurried forward. The barrage was excellent. On reaching the enemy wire, the men pushed the torpedo well in, though not without difficulty, for it was heavy and the wire was very thick. They then withdrew, except the officer and one Royal Engineer who remained to light the fuse. As soon as this had been done, the two rushed back about thirty yards and threw themselves flat on the ground. Almost at the same moment the torpedo exploded with a terrific crash. Meanwhile, the raiders, in column of parties, had advanced to a position about forty yards from the enemy wire. Immediately the torpedo exploded they rushed forward, only to find that much of the wire still remained uncut. Capt. Mowat, Sergt. Moscrop and others flung themselves upon it. Slashing at it with bill-hooks, and hurling great chevaux-des-frises to one side, they forced a passage. Sergt. Moscrop was the first to enter the trench, and he was quickly followed by all the men of the flanking parties. By 10-6 p.m. every man was in the trench and at work. The left flank party came upon an enemy sentry post almost at once. One unwounded prisoner was taken and was passed out of the trench to Capt. Mowat, who was waiting on the parapet. The rest of the Germans were killed. The party then began to work its way along the trench to its left. A second enemy party was encountered, and, for a short time, held up the advance. But half of the British party was working on the parapet. Cpl. E. Jackson, who was in command of these, quickly worked round the Germans, dropped into the trench behind them, and attacked them from the rear. One was taken, the rest were killed. But the prisoner, after his capture, fired at and wounded Moscrop; so he was promptly killed. The party then continued its way towards the left, where it became engaged with some German bombers. These it successfully held at bay until the recall signal was heard.
