Cook, whose Shock Troops won the Charles Taylor Prize for Literary Nonfiction, insightfully examines the 1917 battle of Vimy Ridge and evolving perceptions of it as Canadians prepare to commemorate its 100th anniversary. Four Canadian divisions fought at Vimy, and after four days, the Canadians succeeded where other Allied forces had failed, taking the strategic ridge from the occupying German Sixth Army, albeit at the cost of nearly 3,600 Canadian lives. It was a battle that shaped the still-forming Canadian identity as Canada evolved from colony to dominion to sovereign nation, and the battle has sometimes been described as "the birth of a nation." Although Cook sees that description as myth, and one that has been used by some politicians to promote their own agendas, he writes that it is one of Canada's most enduring narratives. He analyzes the ways that subsequent generations have commemorated Vimy: some made grand speeches and iconic memorials, but others, disenchanted with war, saw the battle as a terrible waste of human life. Covering a century in fewer than 500 pages, Cook's account is necessarily highly compressed, but he effectively conveys a complex topic in a few well-chosen words, showing how Vimy came to hold a place in the Canadian consciousness that no other battle does.
