Attacks on U-135 during this patrol
10 Aug 1942
18.25 hrs, north of Cape Ferrol, Spain, outbound: the boat was strafed by a Czech-crewed Wellington (RAF Sqdn 311/H, pilot F/O J. Nývlt) which also dropped four depth charges. The boat returned fire with the 20mm AA gun during the first attack, and survived six more depth charges dropped after diving.
U-135 sustained only minor damage, but one man was killed by gunfire and another died from wounds an hour after the attack. [Matrosenobergefreiter Emil Hafner, Matrosenobergefreiter Erhard Pömpner]
24 Aug 1942
01.51 hrs, mid-Atlantic: the boat was chasing convoy ONS 122 when she was suddenly illuminated by star shells and forced to dive by gunfire from HNoMS Potentilla. The corvette and HMS Viscount had been depth charging U-705 in the same area for an hour when they detected U-135 on radar. They then dropped 57 depth charges on both U-boats over the next two hours, the final attack being made by HMS Viscount, using a new weapon, Hedgehog. U-135 suffered only minor damage.
