A comprehensive history of Canada’s submarine service and the people who have served in it. Through a Canadian Periscope’s second edition celebrates the story of the Canadian submarine service on the occasion of its centenary in 2014. Created in 1914, at the beginning of World War I, Canada’s submarine force has overcome repeated attempts to sink it since then. Surprise, controversy, political expediency, and naval manipulation flow through its one hundred-year history. Heroes and eccentrics, and ordinary people populate its remarkable story, epitomizing the true essence of the service. Fully updated and with new and restored images, Through a Canadian Periscope offers a colourful and thoroughly researched account of the Canadian submarine service, from its unexpected inauguration in British Columbia on the first day of the World War I, through its uncertain future in the 1990s, to the present day. This vivid account celebrates the individuals who dedicated themselves to the Canadian submarine service and in some instances lost their lives in submarines.
