We Dive at Dawn, first published in 1941, is the authoritative and highly readable account of Royal Navy submarines during World War I (with a final chapter on submarine warfare in the early years of World War II). Written by Lt.-Commander Kenneth Edwards, the book covers a wide-range of topics: the development of the various British submarine classes, German U-boats, encounters with German and Turkish ships and aircraft, sabotage missions on land, anti-submarine techniques (nets, cables, depth-charges), accidents and rescues at sea (including gripping accounts of men escaping flooded submarines). In addition to the workings of the subs themselves, the actions of the men, so many of whom died during their service, are also well-portrayed. One cannot but help to have a great deal of respect for the submariners in, as the author puts it, "e;particularly hazardous service."e; Included are 4 maps and 16 pages of photographs.
