Georg Hoegel, a former U-boat sailor who saw service in World War II, experienced the origin of these emblems of the U-boat service. In this book he keeps alive the memory of the legendary, sometimes very original and unforgotten emblems of German U-boats. The author has been able to collect numerous emblems, coats of arms and markings during long years of painstaking, detailed work, in memory of some 30,000 German U-boatmen, more than 80% of those who served on these boats, who were lost in the war. The brief chronicles and excerpts from first-person memoirs make the history of the German U-boats come alive in an impressive way, and documents the background of their existence. In the current edition, the newest source materials have been included, so that many hitherto unpublished emblems, coats of arms and markings are presented for the first time.
