Attacks on this boat
25 Jun 1941
The British corvette HMS Gladiolus spotted the surfaced boat as she attempted to penetrate into a convoy and forced her to crash dive. Gladiolus then dropped 30 depth charges in 5 runs before being assisted by the corvette HMS Nasturtium which dropped 6 depth charges. The damaged U-boat then surfaced and attempted to run away on the surface which she managed to do. She received at least one hit on the tower from the Gladiolus. (Sources: Blair, vol 1, page 311)
26 Oct 1941
During battle against convoy HG-75, U-71 attacked an escort with a four-torpedo fan, but all missed. The escort fought back with depth charges for 7 hours, damaging the boat so severely that she was forced to return to base. (Sources: Blair, vol 1, page 393)
30 Nov 1941
An attack on 30 Nov, 1941 in the Bay of Biscay west of Nantes, France, in position
46.55N, 07.16W, by depth charges from a British Whitley aircraft (Sqdn 502/B) was formerly credited with sinking the U-206. This attack was in fact against U-71 which escaped undamaged. (Sources: 1991-08-01, FDS/NHB)
5 Jun 1942
On 5 June, 1942 U-71 was damaged about 300km from La Pallice (Grid: BF 9442) at 15h49 by an Australian Sunderland aircraft (Sqdn. 10/U), piloted by S.R.C. Wood, with eight shallow-set depth charges and was then strafed with 2000 rounds of machine-gun fire. The boat dived and had to return to La Pallice (where she had left on 4 June at 19h30) under E-boat escort. She was repaired quickly and resailed a week later on 11 June. Two hours later (on June 5) the Sunderland was attacked by a German Fw 200 Condor aircraft (I./KG 40) and they damaged each other (two airmen from the Sunderland were slightly injured).
12 Apr 1943
At 06.25 hours, the boat was forced to dive by gunfire from a destroyer while shadowing the convoy ON-176. The destroyer dropped 38 depth charges, which caused only minor damage, but the boat had to remain submerged for about 6 hours and lost contact with the convoy. (Sources: Ritschel)
5 recorded attacks on this boat.
General notes on this boat
19 Oct 1941. The boat fired two torpedoes at a cruiser escorted by two destroyers in the North Atlantic, but without success.
17 Apr 1943. On 17 April, 1943 U-631 had a collision with U-71 in the North Atlantic. Both boats were damaged, and U-71 had to return to base.
Men lost from U-boats
Unlike many other U-boats, which during their service lost men due to accidents and various other causes, U-71 did not suffer any casualties (we know of) until the time of her loss.
