Operation Deadlight (post-war Allied operation, info)
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 five ships (the fleet tender Grille with the staff of FdU Norwegen aboard, the fleet oiler Kärnten, the repair ship Kamerun 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.
