Volume two (of a four volume series) reveals the story of the seventy-eight German U-boats that passed through the port of Lorient from July 1941 to July 1942. The book explains the major phases in the Battle of the Atlantic in which U-boats were operating and particularly the surprise attacks on merchant traffic along the American coast. It details the Allied actions against the port of Lorient and their system of defense against the German U-boat arm. Also featured are unedited reminiscences of the U-boat crews' life ashore in Lorient during their patrol arrivals and departures. This work is illustrated with over 500 exceptional war-era photographs as well as maps and plans. A unique color section presents the remains, documents, and memories relating to the presence of the U-boats in Lorient.
