The 14th Canadian Army Tank Regiment was one of the first Canadian armoured regiments to be formed and was also the first to be committed to battle. The action of every one of the regiment's tanks that landed at Dieppe is described in detail by Hugh G. Henry Jr who has spent several years on his research and interviewed all the regiment's survivors. Every Churchill tank and armoured car left behind on the beach is pictured, selected from photographic coverage of the time. In addition, annotated aerial photographs by Jean Paul Pallud pinpoint and identify the position of every vehicle and full crew lists are given for each. The result is a uniquely illustrated after-action report of Canada's worst military defeat.
