THEY SAILED INTO HARM’S WAY dressed as ordinary fishermen, seeking to be attacked by German submarines. This armed team faced danger, frayed nerves, and boredom. Because their mission was secret, they could not explain their service to Canada in the First World War. In this brisk, readable and respectful history, John N. Grant tells the long-buried story of Canada’s Mystery Fleet. He names men who tried to lure U-boats into range, and then sailed into anonymity—until now. Many historic photographs.
