This book describes the organization, lists the units and illustrates the uniforms and equipment of the four Canadian divisions which earned an elite reputation on the Western Front in 1915-18. Canada's 600,000 troops - of whom more than 66,000 died and nearly 150,000 were wounded - represented an extraordinary contribution to the British Empire's struggle. On grim battlefields from the Ypres Salient to the Somme, and from their stunning victory at Vimy Ridge to the final triumphant 'Hundred Days' advance of autumn 1918, Canada's soldiers proved themselves to be a remarkable army in their own right, founding a national tradition.
