From the Chesapeake incident off the coast of Nova Scotia, through the St Albans Raid from Quebec into Vermont, to the reinforcing of garrisons across British North America in response to the Trent Affair, The Civil War Years ranges across the early Canadian landscape. It offers an in-depth survey of Canadian public opinion on the war, the role of Confederate sympathizers in Canada, and the number of Canadians enlisted in the armies of the North and South. The second edition includes a new introduction that provides an overview of Civil War studies since the book's original publication in 1960. The Civil War Years remains a valuable contribution to Canadian history, the history of Canadian-American and Anglo-American relations, and Civil War studies.
