On this date in 1945, Heinz-Wilhelm Eck and two of his former subordinates on the Unterseeboot U-852 were shot in Hamburg for killing the survivors of a sunk target.


The defendants in the U-852 trial. From left to right: Eck, August Hoffmann, Walter Weisspfennig, Hans Lenz, Wolfgang Schwender. The leftmost three were executed.

On March 13, 1944, in the South Atlantic en route to the Indian Ocean, U-852 torpedoed the Greek-flagged Peleus.
