Shesuccessfully avoided the torpedoes fired at her and, with Z14, chasedthe MTBs away from the heavy units. In the subsequent attack byBritish Swordfish torpedo planes, the German fighter escort hit Z7approximately 50 times in her stern with 20mm cannon rounds. 1443:Opened fire at another group of MTBs, again with Z14. The British werequickly driven off and Z7 was able to suspend fire at 1449.
21 Feb 42: Sailed from the Elbe with Z4, Z5, Z14 and Z25 to escort PrinzEugen and Scheer to Norway. Heavy seas and gale force winds afflictedthis force, causing Z7, for one, to suffer rolls of up to 35° and twocrew washed overboard. Two depth charges broke loose and damaged herthrowers. Finally, Z7 suffered five near misses in RAF attacks duringthe morning of the 22nd. On the 23rd Prinz Eugen was torpedoed by aBritish submarine.
23 Feb 42: Arrived Trondheim. Stationed in Trondheim as a part of theescort for Tirpitz and Scheer along with Z4, Z5, Z14 and Z25.
06 Mar 42: Sortied with Tirpitz, Z5, Z14, Z25, T5 and T12 to attack theMurmansk bound convoy PQ.12. The Germans missed this convoy,fortunately, as its escort and covering force collectively consisted of2xBB, 1xBC, 1xCV, 1xCA, 1xCL, and 12xDD. However, the British boundconvoy PQ.8, escorted by only two minesweepers and two corvettes wasalmost encountered instead.
07 Mar 42: Intercepted a Soviet steamer straggling from PQ,8. TheGerman destroyers have a difficult time sinking her: Z7 fired a torpedo,which missed after Z14’s gunfire wasn’t up to the challenge. Finally,Z7 and Z14 teamed up to sink her with their main batteries. Z7attempted to refuel from Tirpitz that night, but sea conditionsprevented this mission from being accomplished. Z7 and Z25 were forcedto return to Tromso to refuel.
Late Mar 42: Dispatched to Kirkenes to join the Arctic destroyer group.
11 Apr 42: Z7, Z24 and Z25 sortied against PQ.14. Poor weather and alack of initiative combined to make this mission a failure.
30 Apr 42: Z7, Z24 and Z25 sortied against PQ.15/PQ.11 and the lightcruiser Edinburgh, torpedoed by U456 earlier in the day.
01 May 42: PQ.15 sighted southwest of Bear Island. The escort consistedof HMS destroyers Amazon, Bulldog, Beagle and Beverley and the corvetteSnowflake. The sea was littered with ice floes and the convoy itselfhugged the edge of the pack ice to reduce the directions from which theGermans could attack. Collectively the British brought 6×4.7″ and 3×4″guns and 14×21″ torpedo tubes to the battle in their four elderly andheavily modified ships (Beverley was the ex USN “four piper” Branch)compared to the German total of 5×5″ and 8×5.9″ guns and 24×21″ torpedotubes. 1405: Z7 opened fire on one of the destroyers, claiming hits.She avoided a torpedo counterattack. During the afternoon the Germansmade six attempts to break through to the convoy, exchanging gunfire andtorpedoes from ranges between 9,000 to 14,000 meters. They managed tohit Amazon hard and torpedo and sink the Soviet steamer Tsiolkovskiwithout suffering any damage themselves. Z7 fired 380 rounds during the3 ¾ hours that passed before the Germans decided to search for theEdinburgh, the primary objective of their sortie.
02 May 42: The German destroyers located the heavily damaged Edinburgh.She was escorted by the destroyers Forrester and Foresight and theminesweepers Harrier, Niger, Gossamer and Hussar. Z7 believed thatEdinburgh was toothless and so she opened fire on Harrier, closing at 21knots in a heavy snowstorm to deliver a torpedo attack on the cruiser.When she was only 800 meters distant, Edinburgh opened fire veryeffectively. The time was approximately 0640 hours. Edinburgh’s secondsalvo hit twice in Z7’s number 1 and 2 turbine rooms, bring the Germanship to a halt. She had only launched one torpedo and her #1 gun wasout of action. She fired four more torpedoes under manual control at adestroyer target, 4,000 meters away, but all missed or were avoided.At 0730 abandon ship was ordered. Meanwhile Forrester and Foresightclosed and brought Z7 under fire, starting a fire in her mess decks,flooding magazines 1 and 2 and putting boiler room #2 out of service.Z24 and Z25 intervened, seriously damaging both British destroyers inthe process . Z24 came along side at 0750 to take off survivors whileZ25 made smoke. In the pitching sea this proved a difficult task andnot until 0815 was she able to disembark the majority of Z7’s crew. Z7sank shortly after at 72° 20′ N and 35° 15′ E when her scuttling chargesexploded. Only eight of her crew died while 45 were wounded. (U88 alsoparticipated in rescue operations rescuing another 56 between 1300 and1500 hours).
Z7 was revenged because Z24 had put another torpedo into Edinburgh whichresulted in the British cruiser being scuttled. With both Forrester andForesight heavily damaged, this action was, in terms of resultsachieved, one of the most successful surface engagements conducted bythe Germans during the war. Yet, Z24 and Z25 might have inflicted moredamage by ignoring rescue operations at a time when the Edinburgh hadjust been torpedoed and both Forrester and Foresight were dead in thewater. With a little more resolution, the engagement could have been amajor German victory. In their defense, the Germans mistook the fourminesweepers for destroyers and so believed they were facing a farlarger force than was the case.
