Based on massive research, this is the best and most complete account of Canadians in the Spanish Civil War we are ever likely to get.

- J.L. Granatstein, author of Canada's Army: Waging War and Keeping the Peace

You will find a painstaking account of the courageous band who chose to fight fascism before it was politically fashionable and the tough battles they fought with little training, lousy equipment and military leadership that was haphazard at best ... Adventurers, idealists, people looking for work and a cause, they deserve our respect. Petrou’s often dry, detailed account allows us to understand that they may have been renegades but they were also soldiers, not of fortune but of commitment and dreams.

Renegades is the fullest and most authoritative account yet written of Canadian volunteers in the Spanish Civil War and a valuable contribution to the history of the International Brigades. Michael Petrou draws on many new archival sources to present a vivid, rounded, and illuminating account of the almost 1,700 Canadians who served in Spain. While essentially a group biography, there are also some fascinating vignettes of individual volunteers, notably Dr Norman Bethune.

Michael Petrou’s Renegades isn't the first account of the Canadians who fought in Spain’s uncivil war, but it does feel like we now have the whole story in hand – as much of it, anyway, as we're ever going to see emerge from the fog of that war. Painstaking and clear-eyed, what lends it heft is the volume and rigour of the research that Petrou, a senior writer at Maclean’s, has marshalled. There’s a good deal that's new, too, thanks to Petrou’s access to the archives of Moscow’s Communist International, as well as the mining he’s done of Canadian archives, including newly declassified RCMP files.

A fascinating account of a little understood conflict, packed with information never before published ... For anyone interested in the history of Canada and the struggle between democracy and totalitarianism, Petrou’s masterful account is required reading.

- Paula Adamick

All the good components of a war history are present here: statistical analysis of who the soldiers were, why they fought, and how their ideals were tested; incompetent officers sacrificing their men for the sake of appearances; and much demonstration of the absurdity of war, both in situ and in retrospect. Petrou does a fantastic job of continuously relating everything back to the why of the war, and how common wartime situations became a fight in the struggle of communism versus fascism.
