Personal information
Karl-Heinz Moehle began his naval career in April 1930. After some months on the line ship Schleswig Holstein, he transferred to the U-boat force in March 1936, and in October 1937 commissioned U-20. He made six patrols, mostly in the North Sea, and sank eight ships.
He left U-20 in January 1940 and four months later commissioned U-123, one of the most famous U-boats of the war.
Moehle's second patrol in the North Atlantic was outstanding. On the morning of 23 November, 1940 he attacked the convoy OB-244 and in five hours sank five ships for a total of 23,084 tons. Due to damage sustained in a submerged collision with a sunken ship, U-123 was then forced to return to base. After four patrols Moehle turned over command of U-123 to Kptlt. Reinhard Hardegen.
From June 1941 to the end of war Moehle was the commander both of the 5th flotilla and of the U-boat base Kiel. In June 1945 he was arrested and in the autumn of 1946 tried for passing on the Laconia order to the U-boat commanders. He was condemned to five years imprisonment, being released in November 1949.
