Korvkpt. Karl-Friedrich Merten
After a ten-year stint on warships and serving on the WWI battleship Schleswig-Holstein during the attack on Westerplatte which started the invasion of Poland in September 1939, Merten joined the U-boat arm on 1 May 1940. He operated all over the world, patrolling in the Atlantic, the Caribbean and the Indian Ocean. U-68 was in wolfpack Eisbär (Polar bear), which in the course of a few weeks during September/October 1942 sank more than 100,000 tons of shipping off South Africa.
In January 1943 Merten became the commander of the 26th (Training) Flotilla U-boat Flotilla at Pillau. There the new U-boat crews received their final training before going to the front. In March 1943 Merten transferred to command the 24th (Training) Flotilla at Memel. This was the training flotilla for future U-boat commanders.
After the war Merten salvaged sunken ships in the Rhine with another famous former U-boat commander, Heinrich Lehmann-Willenbrock. He later worked in the shipbuilding industry.
