General Events during this patrol
1941
29 Mar 1941. At 19:30 hrs on 29 March 1941 U-107 left Lorient, France under the command of Kptlt. Günther Hessler on what would become the most successful U-boat patrol of the entire war. She sailed with U-94, commanded by Kptlt. Kuppisch, but then U-107 turned south. Her area of operations was around the Canary Islands and nearby Freetown, where she sank 14 ships with a total of 86,699 tons. On 3 and 4 of May U-107 refuelled from the German supply ship Nordmark, together with U-105. Five days later U-107 transferred 14 torpedoes, food, water and more fuel from the supply ship Egerland. U-107 returned to Lorient on 2 July 1941. Kptlt. Hessler married Karl Dönitz's daughter Ursula in November 1937. At that time he was serving on torpedo boats, but he joined the U-boat force in April 1940. Because Hessler was his son-in-law, Dönitz felt uncomfortable about bestowing the Knights Cross his achievement entitled him to, and eventually Grand Admiral Raeder signed the papers.
9 May 1941. U-107 was supplied with 14 torpedoes and provisions by the German support ship Egerland, which was disguised as an American vessel. This is one reason why there were rumours after the war of American ships assisting U-boats.
