Sunk at 0409hrs on 4 May, 1944 in the Mediterranean north of Constantine, in position 37.49N, 05.39E, by depth charges from the US destroyer escorts USS Pride and USS Joseph E. Campbell, the French destroyer escort Sénégalais and the British escort destroyer HMS Blankney. 3 dead and 49 survivors.
This boat was unlucky enough to be the first victim to an allied sub-hunting tactic in the Mediterranean known as Swamp. This tactic simply called for the area of a known or suspected U-boat to be packed with surface escorts and patrol aircraft. They would then systematically and continually search the area and force the U-boat to remain submerged until its batteries ran out or try to escape at night on the surface. Either was almost hopeless.
U-371 was spotted recharging her batteries on the surface off Djidjelli on the Algerian coast on the night of 2/3 May 1944 and was immediately detected and the area was swamped with 6 escorts and 3 aircraft squadrons. They hunted the boat until the early morning of May 4 when Oblt. Fenski had to surface the boat and save his crew. He had managed to fight back and torpedoed and damaged the US destroyer escort USS Menges and the French destroyer escort Sénégalais before calling it quits.
Attacks on this boat
30 Jun 1941
12.30 hrs, Bay of Biscay, inbound: a Blenheim (RAF Met Flt 1404/G, pilot FltLt D.F. Wykeham-Martin, RAFVR) surprised U-371 after being misidentified as a German Ju88, and dropped two 250lb A/S bombs and one 250lb GP bomb in a dive bomb attack from astern, the bombs detonating 30 yards off the starboard bow. The U-boat then dived, but was attacked from the port beam with another GP bomb, which detonated over the bows but she escaped without damage. (Sources: KTB U-371/ADM 199-1781)
30 Jun 1941
17.05 hrs, Bay of Biscay, inbound: a Beaufort (217 Sqn RAF/R) on A/S sweep (misidentified as Sunderland) tried to surprise U-371 with a dive bomb attack out of the sun, but the boat managed to dive in time and the two 250lb A/S bombs released detonated about 40 feet ahead of the bows. The aircraft turned and dropped four depth charges ahead of the dive point, but U-371 had already dived below 40 metres and escaped without damage. (Sources: KTB U-371/ADM 199-1781)
7 May 1942
The boat was depth charged by two sub chasers and was so severely damaged that she had to return to base.
7 Jan 1943
12.04 hours, Mediterranean, off Algiers: U-371 attacked three M/S trawlers and sank HMS Jura. The other two armed trawlers, HMS Ruskholm and HMS Stronsay, then dropped 24 depth charges in five attack runs before losing contact at 12.31 hours. The boat escaped undamaged. (Sources: ADM 199/1321)
23 Feb 1943
At 14.06 hours, the boat was located by HMS Felixstowe after the sinking of Fintra about 30 miles east-northeast of Algiers. The minesweeper dropped 25 depth charges in six attacks between 14.10 and 15.08 hours and observed air bubbles rising to the surface after the second and sixth attack. Her commander considered the U-boat sunk, but U-371 was not damaged and escaped by getting closer to the coast and heading east. (Sources: ADM 199/1784)
5 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-371 did not suffer any casualties (we know of) until the time of her loss.
