German submarine U-481

German submarine U-481 was a Type VIIC U-boat of the Nazi German Kriegsmarine during World War II. The submarine was laid down on 6 February 1943 at the Deutsche Werke yard in Kiel, launched on 25 September 1943, and commissioned on 10 November 1943 under the command of Oberleutnant zur See Ewald Pick.

1st patrol
U-481 left Kiel on 19 June 1944 under the command of Kapitänleutnant Klaus Andersen, and sailed to Reval (now Tallinn, Estonia) via Helsinki. She departed Reval on her first war patrol on 5 July and sailed east into the Gulf of Finland to Soviet waters. On 30 July she attacked a group of Soviet Navy coastal minesweepers with torpedoes, sinking two (KT-804 and KT-807) and damaging another (KT-806). On the same day the U-boat was attacked while in Narva Bay by two Ilyushin Il-2 Shturmovik aircraft from the 35th Assault Air Regiment (35. ShAP), and managed to damage one enough to force the pilot to ditch his aircraft. The U-boat arrived back at Reval on 4 August.

2nd patrol
U-481 sailed again from Reval on 10 August 1944, and patrolled Soviet waters with no success, before arriving at Königsberg in East Prussia, on 21 August.

3rd patrol
Departing Königsberg on 16 September 1944, the U-boat patrolled the Baltic, and on 15 October sank three small Finnish Galeas sailing barges (Dan, Endla and Maria) off Osmussaar, Estonia, with shell-fire, before arriving at Danzig (now Gdansk) on 26 October.

4th patrol
U-481 sailed from Danzig on 2 November 1944, returning to the Gulf of Finland, and on 9 November off Cape Pakri she torpedoed and shelled the Soviet 1,000 ton barge 112600, sinking her. On 28 November she sank the Soviet 108 ton coastal minesweeper T-387 in the same area. The U-boat returned to Danzig on 22 December.

5th patrol
After returning to Kiel to be fitted with a 'schnorchel' in February 1945, the U-boat sailed for Horten in Norway, making her final patrol along the Norwegian coast from 7 April to 4 May, finally arriving at Narvik only a few days before the German surrender. On 12 May all U-boats in the Narvik area were ordered by the Allies to sail to Skjomenfjord to avoid conflicts with the Norwegians. On 15 May four ships; the fleet tender Grille with the staff of FdU Norwegen on board, the fleet oiler Kärnten, and the depot ships Huascaran and Stella Polaris, and fifteen U-boats including U-481, sailed for Trondheim, but were intercepted after two days by the Royal Navy's 9th Escort Group and officially capitulated. The ships were allowed to proceed to Trondheim, but all the U-boats were escorted to Loch Eriboll, Scotland, arriving on 19 May. Later transferred to Loch Ryan, U-481 was sunk at position in 56.18333°N, -10°W as part of "Operation Deadlight" on 30 November 1945.
