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.

Attacks on this boat
19 Jul 1944
At 19.15 hours, U-716 was attacked by Liberator FL985 (59 Sqn RAF/F, pilot FO R.C. Penning) on A/S patrol in the Norwegian Sea after being spotted by the starboard beam gunner. The aircraft attacked despite intense but inaccurate AA fire which was returned by the nose gunner, flying directly over the U-boat from the port quarter and dropping six depth charges. The last two overshot, but the other four straddled the boat which was lifted and badly shaken by the explosions, causing water to enter through the galley hatch that sprang open and disabling all electric devices including the radio transmitters. The aircraft immediately attacked again and dropped two depth charges that were seen to fall equidistant from bows in a perfect straddle. The Germans continued to fire at the circling aircraft but their aiming was bad as the crewmen lacked training on the new 37mm AA gun and five men on the bridge had been slightly wounded by splinters from machine gun rounds hitting the armor plating of the AA guns. The U-boat escaped further attacks by diving at 19.41 hours, but the damage forced U-716 to abort her patrol. (Sources: Norman Franks, ADM 199/1786)
23 Apr 1945
The U-716 was depth charged in the Arctic Sea by a hunter-killer group. Due to the damage incurred the boat had to return to base.
2 recorded attacks 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-716 did not suffer any casualties (we know of) until the time of her loss.
