On 29 April, the convoy was spotted by a German
Junkers Ju 88 reconnaissance aircraft and
U-boats. On 30 April, two days out from Murmansk, and made attacks on the convoy to no effect. Later that day, hit
Edinburgh twice. One torpedo hit the cruiser's forward boiler room while the other hit the cruiser's stern, destroying its rudder and two of its four propellers.
Edinburgh was badly damaged but remained afloat; it left the convoy and turned towards Murmansk, escorted by
Foresight and
Forester. Several ships were sent from Murmansk to assist
Edinburgh, among them the British s , , and , the Soviet destroyers and , the Soviet
guard ship Rubin and a
tug.
1 May The German command sent the three destroyers of , , and (
Alfred Schulze-Hinrichs), to attack Convoy QP 11 and then sink HMS
Edinburgh. The German ships reached the convoy in the afternoon on 1 May. The weather was cold; intermittent snow and rain limited visibility.
Hermann Schoemann opened fire at 14:05. The four British destroyers formed up between the German destroyers and the convoy and engaged them at a range of about .
Amazon was hit twice and severely damaged. At 14:30 a German torpedo salvo hit and sank the Soviet freighter
Tsiolkovski. At 17:50 the German destroyers turned to pursue
Edinburgh.
2 May The flotilla found
Edinburgh east of the convoy at 06:17 on 2 May, moving at .
Edinburgh was escorted by
Foresight,
Forester, the four British minesweepers and
Rubin,
Gremyaschi and
Sokrushitelny had returned to Murmansk due to a lack of fuel. The three German destroyers engaged the British ships. Due to the damage caused by
U-456,
Edinburgh was unable to manoeuvre and could only steam in circles. A snow shower separated
Herman Schoemann from the other German destroyers and it attacked the British ships alone.
Edinburghs targeting systems had been destroyed by the torpedo explosions but its gunners managed to hit and cripple
Hermann Schoemann. At 18:45,
Z24 and
Z25 arrived.
Z25 hit and disabled
Forester and then badly damaged
Foresight. At 18:52 a salvo of torpedoes from one of the German destroyers missed
Foresight and
Forester but one torpedo kept going and struck
Edinburgh in the middle of its left side, opposite the hole made by
U-456s torpedo. The German ships soon withdrew, possibly because they overestimated the strength of the British minesweepers. At 08:15,
Z24 rescued most of the crew of
Hermann Schoemann who were still on the deck and then scuttled it. More survivors from
Hermann Schoemann who were in life rafts were later rescued by
U-88.
Harrier and
Gossamer took survivors off
Edinburgh, which was then scuttled by a torpedo from
Foresight. ==Aftermath==
