(From the picture by Christopher Clark. By permission of The Sphere.) "The 4th Canadian Battalion at one time came under a particularly withering fire. For a moment—not more—it wavered. Its most gallant commanding officer, Lieutenant-Colonel Birchall, carrying, after an old fashion, a light cane, coolly and cheerfully rallied his men, and at the very moment when his example had infected them, fell dead at the head of his battalion. With a hoarse cry of anger they sprang forward as if to avenge his death. . . . After a hand-to-hand struggle the last German who resisted was bayoneted, and the trench was won."
