Walther Kölle joined the German Navy (Reichsmarine) in 1926. He served on the heavy cruiser Graf Spee until August 1939 as was thus not on its famous patrol into the South Atlantic. Kölle was stationed at the Naval College at Mürwik from Sept 1939 to Aug 1940 when he became the senior naval officer of the base Flushing until Oct when he joined the U-boat force.
From Nov 1940 to July 1941 Walther Kölle went through U-boat training, he then familiarized himself with a new U-boat (Baubelehrung) at Bremen, Germany from July until he took command of the new U-boat Type IXC boat U-154 on 2 Aug 1941.
KrvKpt Walther Kölle commanded the U-154 on 3 patrols. His first was short and without success but his second, into the Caribbean, was successful as he sank 5 ships for almost 29,000 GRT during his 60 days at sea. His third patrol was even longer at 81 days, also into the Caribbean and then Gulf of Mexico but this time he only sank 2 ships for 2,600 GRT.
When arriving to France after the third patrol in late August 1942 Kölle was sent to other assignments and his boat was given to Heinrich Shuch whose boat U-105 had just been bombed and seriously damaged (Blair, 1996).
Walther Kölle would serve in several staff positions to the end of the war. During Jan - Sept 1944 he was First Officer on the proposed merchant raider Hansa but the ship never sailed.
