October and Sarthe on the same date, both in the area of the Cape of Good Hope. She also disposed of Belgian Fighter on the ninth. Turning for home on 16 October, she sank City of Cairo on 6 November. U-68 returned a month later to Lorient on December 6. Sixth patrol The boat's sixth patrol in the first half of 1943 was again to northern South America. Having sunk two ships, she was attacked by a US Mariner flying boat on 2 April; damage was slight. Seventh and eighth patrols U-68 was attacked by one of four British De Havilland Mosquitos on the western edge of the Bay of Biscay on 14 June 1943. One man was killed, three were wounded Patrol number eight was relatively uneventful. Ninth patrol The boat returned to her most successful hunting ground - the South Atlantic. In another mammoth patrol (107 days), she sank four more ships. One of them, the Norwegian tanker Litiopa, had numerous torpedoes and rounds from the deck gun fired at her, but stubbornly refused to succumb. Having been initially encountered at night on 21 October 1943, it was not until the following day that she sank. The Litiopas sole escort was the mine-sweeping trawler HMS Orfasy. She was sunk relatively easily on 21 October before the attack on the tanker. The other two ships were New Columbia, (sunk southwest of Bingerville, Ivory Coast) on 31 October and the French Fort de Vaux on 30 November. The latter vessel met her end after 'Aphrodite' radar decoys had been used to lure the escort vessels away. U-68s inbound route took her close to the northwest Spanish coast. She docked at Lorient on 23 December 1943. Tenth patrol and loss The boat left Lorient for the last time on 22 March 1944. On 10 April, she was sunk at position , northwest of the Portuguese island of Madeira, by depth charges and rockets from Grumman Avenger and Grumman Wildcat aircraft from the United States escort carrier . 56 men died; there was one survivor, who was the lookout left top-side when the submarine crash-dived in an attempt to avoid attack. Wolfpacks U-68 took part in one wolfpack, namely: Eisbär (25 August - 1 September 1942) Summary of raiding history References Notes Citations Bibliography External links 1940 ships German Type IX submarines Ships built in Bremen (state) U-boats commissioned in 1941 U-boats
