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 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 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.
