Very early in the small hours of Friday morning the first British reinforcements arrived in the gap. They were a strange mixture of units, commanded by Colonel Geddes of the Buffs—to be ever afterwards gloriously known as Geddes’s Detachment. But our concern for the moment is with the Canadians. The reinforcements from the 1st Brigade counter-attacked, along with Geddes’s Detachment, early on the Friday morning. Meantime the Canadian 3rd Brigade was in desperate straits. Its losses had been huge, and its survivors were still weak from the effects of the gas. No food could reach it for twenty-four hours. Holding an acute salient, it was under fire from three sides, and by evening was driven to a new line through St. Julien. The enemy had succeeded in working round its left, and even getting their machine-guns behind it. About 3 o’clock on the morning of Saturday, the 24th, a violent bombardment began. At 3.30 there came a second gas attack. The gas, pumped from cylinders, rose in a cloud which at its greatest was 7 feet high. It was thickest close to the ground, and filled every cranny of the trenches. Instinct taught some of the men what to do. A wet handkerchief wrapped round the mouth gave a little relief, and it was obviously fatal to run back, for in that case a man followed the gas zone. Its effect was to produce acute bronchitis. Those smitten by it suffered horribly, gasping and struggling for breath, and in many cases becoming temporarily blind. Even 1,000 yards from the place of emission troops were afflicted with violent sickness and giddiness. Beyond that distance it dissipated itself, and only the blanched herbage marked its track. That day, the 24th, saw the height of the Canadians’ battle. The much-tried 3rd Brigade, now gassed for the second time, could no longer keep its place. Its left fell back well to the south-west of St. Julien. Gaps were opened in its front, and General Currie’s 2nd Brigade was now left in much the same position as that of the 3rd Brigade on the Thursday evening. About midday a great German attack developed against the village of St. Julien. The remnants of the 13th and 14th battalions—the Royal Highlanders of Montreal and the Royal Montreal Regiment—could not be withdrawn in time, and remained—a few hundred men—in the St. Julien line, fighting till far on in the night their hopeless battle with a gallantry which has shed eternal lustre on their motherland. Not less fine was the stand of the 8th Battalion (the 90th Winnipeg Rifles) in the 2nd Brigade at the very point of the Salient. With its left in the air it held out against crazy odds till reinforcements arrived.
