The U-boats that were in the Narvik area at the end of the war were all moved to the Skjomenfjord upon Allied orders to avoid conflicts with the Norwegians on 12 May. On 15 May, a German convoy of four ships (the fleet tender Grille with the staff of FdU Norwegen aboard, the fleet oiler Kärnten and the depot ships Huascaran and Stella Polaris) and 15 U-boats (U-278, U-294, U-295, U-312, U-313, U-318, U-363, U-427, U-481, U-668, U-716, U-968, U-992, U-997 and U-1165) left for transfer to Trondheim, but was intercepted after two days by the 9th Escort Group off the Norwegian coast and officially capitulated. While the ships were allowed to proceed to Trondheim, the U-boats were escorted to Loch Eriboll, Scotland, arriving on 19 May. All U-boats were later that month transferred to Lisahally or Loch Ryan for Operation Deadlight.

Attacks on this boat

16 May 1944
At 17.15 hours, the boat was attacked by the Norwegian Sunderland aircraft JM667 (330 Sqdn RAF/V, pilot S/Lt C.T. Johnsen) west-northwest of Alesund, while on transfer between Bergen and Skjomenfjord. U-668 met the initial approach with heavy AA fire and evaded the single depth charge dropped. Minor damages were caused by the four depth charges exploding on the port side during the second attack run and one crewman was wounded by a bullet. AA fire hit the Sunderland several times in the fuselage and the starboard wing, damaging both starboard engines. The front gunner was killed and two more crewmen were wounded by a shell exploding in the cockpit area. Flying on three engines the aircraft made it barely back to Sullom Voe.

1 recorded attack on this boat.

Men lost from U-boats

Unlike many other U-boats, which during their service lost men due to accidents and various other causes, U-668 did not suffer any casualties (we know of) until the time of her loss.
