(11-43-17.03.44). was outstanding in point of U-boat service and good fortune. Before the war he had served in U-9 under Mathes. In 1939 he joined U.53 under Kutschmann and was transferred before this U-boat left on her first and fatal patrol. Until January 1941 Freudig served under Prien in U.47. In February U.47 sailed on patrol and never returned. Late in 1941 Freudig stood by the construction of U.331 and made all patrols except the last. Early in 1943 he was drafted to U.801. Freudig never thought when, after leaving U.331, he was instructing at Flensburg that he would sail in U-boats again. He credited his last appointment afloat to the fact that the U-boat arm was so seriously lacking in experienced personnel. This prisoner stated that in recent months a large number of Telegraphist Chief Petty officers were being sent to U-boats for this reason. As a group the petty officers of U.801 were quite exceptionally experienced. Pow." birthplace Hamburg serial/entry 28 / 36.T. awards DKiG. 31.03.44.(U-801). |
