Oblt. Siegfried Koitschka after patrol
Siegfried Koitschka began his naval career in April 1937. After some months on the cruiser Admiral Hipper and in a training unit he transferred to the U-boat force in June 1940.
Six months later he became second watch officer (II WO) on the newly commissioned U-552, the famous "Red Devil Boat". He accompanied the U-boat on her first six patrols under the command of Erich Topp. He left U-552, certainly with a lot of combat experience, in December 1941.
After the commander training course in the 26th (Training) Flotilla, he became commander of the school boat U-7. But in December of the same year he took command of his own front boat, the type VIIC U-boat U-616. After one patrol in the North Atlantic he managed to break through the Straits of Gibraltar in May 1943.
After six patrols in the Mediterranean, where he sank a US destroyer in October 1943 and damaged two ships in May 1944 with a total of more than 17,000 tons (he claimed more sinkings, but they were not confirmed successes), he left Toulon on 30 April for his last patrol.
Two weeks later, east of Cartagena, Spain, one of the longest U-boat hunting operations of the war took place. After torpedoing two ships, Kptlt. Koitschka with U-616 was located by US destroyers on 14 May, 1944. The next three days U-616 was attacked by the destroyer and also British Wellington aircraft before being forced to surface on the 17 May. All the crew survived the scuttling of the U-boat (Niestlé, 1998).
Siegfried Koitschka spent more than two years in Allied captivity before he was released in June 1946.
