Kriegsmarine U-boats 1939–45 (1)

This, the first of two volumes on Germany's World War II U-boats, traces their development through: the early U-boats of the Kaiser's navy; the prohibition on Germany having U-boats following the Armistice in 1918 and the subsequent Treaty of Versailles; the secret development of U-boats using a "cover-firm" in Holland; and culminating in the formation of the 1st U-boat Flotilla in 1935 with the modern Type II. The operational history section includes examples from the classes Type VIIA, Type VIIB, VIID, VIIE and VIIF before concentrating on the mainstay of the U-boat arm, the Type VIIC. Comparisons are also made with the standard Allied submarines, their strength and weakness and U-boat tactics.
