Book excerpt: Canada was the first Commonwealth country to send troops to Britain in 1939. During 1939-45 hundreds of thousands of Canadians - more than 40 per cent of the male population between the ages of 18 and 45, and virtually all of them volunteers - enlisted. Canadians fought with tragic courage at Hong Kong and Dieppe; with growing strength and confidence in Sicily, Italy and Normandy; and finally provided an entire Army for the liberation of NW Europe. This concise account of an extraordinary national effort in the cause of freedom is supported by data tables, photos, and eight colour plates by Canada's most knowledgeable military illustrator.
