01 Apr 35: Laid Down
14 May 36: Launched
13 Sep 38: Commissioned.
01 Sep 39: With the Reconnaissance Force (Vizeadmiral Densch). This included: light cruisers Nurnberg (FS) Leipzig, Koln, destroyers (Konteradmiral Lutjens) Z1 (FS) Z2, Z4, Z8, Z9, Z10, Z11, Z14, Z15, Z16, 6xS-Boats, 21xMS, 5xEscorts and 10xUB. This force was excessive for the task of containing the Polish naval units in home waters (destroyer Wicher, ML Gryf and 5xSS with smaller auxiliaries.) and was quickly allocated other tasks.
03-20 Sep 39: With forces laying the West Wall mine barrage in the North Sea. Ships involved in one or more operations included Nurnberg, Leipzig, Koln, Konigsbeg and Emden; the 1st DD FLOT (Z2, Z4, Z14, Z15, Z16) 2nd DD FLOT (Z1, Z6, Z7, Z8), 4th DD FLOT (Z10, Z11, Z12) 5th DD DIV (Z17, Z18, Z19 and Z20, 5th TB FLOT (Greif, Mowe, Albatros, Kondor, Falke) and the 6th TB FLOT (Leopard, Seeadler, Ilis, Wolf and Luchs) along with 3xML.
04 Sep 39: An anti-sweep device exploded while Z10 was loading mines for the operations specified above. This accident killed two, wounded six and caused light damage to her stern. This was the only losses suffered by the Germans during their initial large scale minelaying operations.
28-30 Sep 39: Z10 with Z14, Z15 and 4xTB conducted mercantile warfare in the Skagerrak and Kattegat, stopping and inspecting 45 vessels.
22-24 Oct 39: Z10 with Z3, Z11, Z12, Z14 and Z15, conducted an anti-shipping patrol in the Skagerrak.
18-19 Nov 39: Z10 with Z15 and Z16 conducted an offensive mining operation off the Humber Estuary. This field sank seven ships of 38,710 GRT. On their return to home waters, the force was met by Leipzig and the 6th TB FLOT (4xTB).
27-28 Nov 39: Z10 conducted an anti-mercantile sweep off the southern coast of Norway with Z11, Z20, Z14, Z3 and Z15. Heavy weather caused the operation to be aborted and Z3 suffered serious damage while returning to port.
06-07 Dec 39: Z10 (FS with Fregattenkapitan Bey commanding) escorted Z12 on an offensive mining operation off Cromer. At 0255, just 15 minutes after the lay had been completed, the German ships sighted the British destroyers Juno and Jersey about 8,000m away. The Germans turned to a parallel course and by 0310 had closed range to 4,600m while remaining undetected themselves. Z10 fired three torpedoes at Juno, the lead British ship while Z12 sent four more torpedoes at Jersey. Z10's salvo missed, but Z12 scored with one torpedo. The blow started a large fire and caused damage that required ten months to repair. Juno turned back to assist her mate, making smoke; apparently the British believed a submarine had attacked them. Bey still had the advantage of surprise and at least five more torpedoes on Z10, but he decided to break off the action and return for home. Two ships of 5,286 GRT were sunk by the minefield.
Dec 39: Entered dock for refit.
May 40: Completed refit.
04 Jun 40: Departed Kiel with Gneisenau, Scharnhorst, Hipper, Z7, Z15 and Z20 to attack Allied supply lines off northern Norway (Operation Juno). Z10 was working up at the time and not considered fully battleworthy, but the shortage of escorts required her participation.
07 Jun 40: After refueling off the coast of Norway (a process which required eighteen hours), German aerial reconnaissance reported two groups of Allied shipping. Hipper and the destroyers were detached from the battlecruisers to attack the southern group.
08 June 40: At 0555 Hipper located a tanker and, with assistance from Z10, attacked her and her escort, the trawler Juniper. Z10 finished off the trawler with gunfire and the burning tanker with a torpedo. She then sighted the large transport Orama and with Z20 chased her until Hipper came up. Both the cruiser and Z10 pounded this vessel with gunfire, and then Z10 sank her with two torpedoes. The German ships conducted rescue operations and saved 274 men.
09 Jun 40: Returned to Trondheim with Hipper and the other three destroyers. Z10 captured a trawler on the way.
10/11 Jun 40: Sortied with Gneisenau and Hipper and Z7, Z15 and Z20 into the Arctic. Poor weather and negative reconnaissance results forced an early end to the operation.
21-23 Jun 40: Scharnhorst, damaged by a torpedo hit during the engagement in which she and Gneisenau sank the British carrier Glorious, departed Trondheim escorted by Z10 with Z7, Z15, Z20 and the TBs Grief, Kondor, Falke and Jaguar. Six Swordfish attacked the force en route, but lost two of their number at no cost to the Germans. All arrived safely at Kiel on 23 Jun.
25-28 Jul 40: Gneisenau had sortied on 20 Jul to cover Scharnhorst's return to Germany. On 20 Jul she was torpedoed in her turn. After temporary repairs, she sailed from Trondheim escorted by Z10 with Nurnberg, Z5, Z14, Z20 and the TBs Luchs, Iltis, Kondor, Jagukar and T5. The force arrived in Kiel on 28 Jul, although Luchs was sunk in passage by a British submarine.
09 Sep 40: Z10 (FS, Kapitan zur See Bey commanding) departed Wilhelmshaven with Z6, Z14, Z16, Z20 to provide escort for a large group of minelayers being deployed to French ports in anticipation of the invasion of England. All arrived safely in Cherbourg on 11 Sep after undergoing an attack by RAF Blenheims on the morning of the 11th.
18 Sep 40: Z10 and the other ships of her flotilla suffered a large RAF raid on Cherbourg. Z10's boats assisted in rescuing survivors from a steamer which was sunk during the attack.
19-20 Sep 40: Bey's force with flagship Z10 , Z6, Z14, Z16 and Z20 sortied from Cherbourg on an offensive patrol into the English Channel, but poor weather caused him to abort the mission. The flotilla then transferred to Brest.
28/29 Sep 40: The Channel destroyer forces conducted an offensive mining operation in Falmouth Bay. Z6 and Z16 escorted the destroyers carrying mines: Z5, Z10 (FS), Z14, Z15 and Z20. This field accounted for five small ships of 2,037 tons.
10 Oct 40: Z10 suffered splinter damaged in an attack on Brest by British Fleet Air Arm Swordfish.
17 Oct 40: Bey sortied from Brest with Z10 (FS), Z6, Z14, Z15 and Z20 on an offensive sweep into the SW approaches of the English Channel. He was surprised at 1700, 40 miles south, southwest of the Scillies by a force of British cruisers and destroyers (Newcastle, Emerald with Jackal, Jupiter, Kashmir, Kelvin, and Kipling). The first notice of the British presence was five shells, fired at extreme range, splashing astern of Z10. The Germans turned toward Brest while the British gave chase. The range closed from 30,000m to 16,000m by 1800: and 6" shells were bracketing the German ships. The British were able to close range so effectively because Z15 was experiencing boiler problems and the need to take evasive action precluded the steering of a straight course. To force the British to do some defensive maneuvering themselves, Z10 and Z20 each fired three torpedoes dead astern while Z15 turned to port and fired four more from 14,500m. The Newcastle's spotter aircraft advised her ship of the torpedoes and at 1841 the cruiser turned to comb them. At 1901 she was bombed by a Do 17. The splashes from the bombs and the smoke from the antiaircraft fire led the Germans to believe they had hit Newcastle with a torpedo. This attack did succeed in opening the range and by 1921 the British had abandoned the chase.
24/25 Nov 40: Bey sortied from Brest into the area off Plymouth with Z10, Z20 (FS), and Z4. The force attacked a fishing fleet without results but subsequently located a convoy of three ships. They sank one of these ships (2,156 GRT) and damaged another. The RN 5th DD FLOT unsuccessfully attempted to intercept the Germans.
28/29 Nov 40: The German destroyer force at Brest (Z10, Z20 (FS), and Z4) commanded by Bey attempted to repeat its success in the waters off Plymouth of four night previous. The force encountered two tugs pulling a lighter and required 35 minutes firing at 300-400m to sink the lighter and one of the tugs (424 tons). More alert than on the previous occasion, the RN 5th DD FLOT (Javelin, Jupiter, Kashmir, Jackal and Jersey) intercepted the Germans. However, each of the three German ships fired four torpedoes before the British were able to get off their opening salvo. The British had only fired twice when their lead ship, Javalin, was hit on her bow and stern by two of Z10's torpedoes. The balance of the British force chased the Germans for two and a quarter hours before breaking off. Z10 was the rear ship and was straddled several times, but never hit. The German force suffered very minor damage and no casualties. Javalin survived.
Early Dec 40: Z10 sailed for Germany with Z20 for refit.
19 May 41: Z10 escorted the Bismarck and Prinz Eugen off the Belt with Z16 and Z23. The 5th MS FLOT also participated. 21 May the force entered Bergan. On the 22nd off Trondheim the destroyers were dismissed.
24 May 41: Z10 sailed from Trondheim for Wesermunde.
11 Jun 41: Z10 with Z16, Z20, Z23, Z24 departed Kiel to escort Lutzow to Trondheim. A solitary Beaufort torpedoed Lutzow at 0220 on 13 June off Karmoy and the force turned back for Germany.
04 Jul 41: 6th DD FLOT (Capt. Schulze-Hinrichs with Z10 (FS), Z4, Z7, Z16 and Z20 Z10 sailed from Bremen bound for a deployment on the Arctic coast. They arrived in Trondheim on the 5th.
10 Jul 41: 6th DD FLOT arrived in Kirkenes on the Arctic coast of Norway.
12 Jul 41: The 6th FLOT sortied to attack Soviet shipping on the Murman.
13 Jul 41: The flotilla including encountered a convoy of one Soviet auxilliary escort, SKR22 (Passat), a former fishing trawler armed with 2x45mm guns and two Soviet trawlers off Cape Teriberka. 0248: In forty minutes of shooting the Germans expended 80% of their main battery ammunition to sink the escort and one of the trawlers. The other Soviet ship escaped. On their passage back to Kirkenes the Germans repelled two Soviet air attacks. Z10 was near missed in the first attack and shot down one plane.
22 Jul 41: The 6th FLOT sortied for another sweep of the Murman Coast, but condenser problems forced Z10 drop out from the formation and Schulze-Hinrichs to shift his flag. She returned to Kirkenes for repairs.
09/10 Aug 41: 6th DD FLOT Z10, Z4 and Z16 sortied toward the mouth of the Kola inlet. They surprised and sank the Soviet patrol ship Tuman (SKR-12) after a gallant resistance, and were then shelled by Soviet shore batteries, which near missed Z4, inflicting some damage. The Germans repelled Soviet air attacks as they withdrew.
30 Aug 41: Z10 escorted a convoy of four steamers from Tromso bound for Kirkenes with Z20, UJ178 and two coastal patrol boats (vorpostenbotte). The British submarine Trident fired two torpedoes at the convoy just 100m off Z10's port bow. Two of the steamers were sunk (of 1,676 crew and passengers aboard the two ships, 342 died). Despite the very good fix on the submarine's location and the proximity of Z10, Trident survived a light two-hour depth charging (only 39 were dropped) with minor damage.
27 Sep 41: Z10, in serious need of refit, departed the Arctic bound for Germany. She entered dock in October.
May 42: Z10 completed her refit and began working up in the Baltic.
15-20 May 42: Operation "Walzertraum:" Lutzow escorted by Z10 with Z4, Z27, Z29 and F1 sailed from Swineminde bound for Kristiansand. The entire force arrived there safely on the 18th and then continued on to Trondheim where they arrived on the 20th.
Jun 42: While at Trondheim Z10 suffered flooding from a valve accidentally left open and was non-operational for the first two weeks in June.
02 Jul 42: Z10 sailed from Trondheim with Tirpitz, Hipper, Z6 Z14, Z20, T7 and T15 to rendezvous at Altenfjord with forces coming from Narvik (Lutzow, Scheer, Z4, Z24, Z27, Z28, Z29, Z30) The mission's ultimate objective was to launch an attack on British convoy PQ.17
03 Jul 42: Z10 ran aground at Grimsoystraumen on uncharted, submerged rocks. Lutzow, Z20 and Z6 shared this fate. The German ships were making the dangerous passage through the fjords at night in an attempt to forestall British aerial reconnaissance. Z10 suffered severe damage to her propellers and shafts and ripped her bottom in several locations.
Jul 42: Z10 slowly returned to Trondheim with Z6 and Z20.
25 Jul 42: Towed from Trondheim bound for Germany with Z6, also under tow.
28 Jul 42: Attacked by RAF Beauforts south of Stavanger.
29 Jul 42: Arrived Kiel. Originally it was estimated six months would be required to repair her damage. This resulted in the order to pay off the ship and break up her crew. Z10's captain, Pfeiffer succeeded in negotiating a reversal of this decision.
End of April 43: Z10 sailed from Germany for the Arctic. Her repairs took longer than Pfeiffer promised.
06-08 Sep 43: Participated in Operation Sizilien: an attack on Spitzbergen with Tirpitz, Scharnhorst, 4th DD FLOT (Z29, Z33, Z31) 5th DD FLOT (Z15, Z27, Z30) and 6th DD FLOT (Z6, Z10 Z20). The destroyers of the 5th and 6th FLOTs embarked a battalion of the 349th Grenadier Regiment, approximately 100 men per ship. The objectives of this operation appear to have been to boast moral and to give the ships involved some badly needed sea time and a taste of offensive operations. Z10 experienced machinery problems en route, however, she was able to continue with the operation. Upon arriving and landing her troops, Z10 was detached to act as anti-submarine screen for Scharnhorst. She refueled from the battlecruiser as her fuel consumption had been unusually high.
25 Nov 43: Departed the Arctic for redeployment south with Z15. Z15 was rammed by a steamer en route.
04-07 Dec 43: Based in Horten in Oslofjord. Participated in two defensive mining operation with Z6, Z31 and 2xML designed to block the entrance to the Skagerrak.
15-19 Feb 44: With Z15 and 2xML participated in laying three defensive mine barrages, Dorothea B, C and D in the northern Skagerrak.
01-02 Apr 44: Laid the Katzbach A defensive mine barrage west of the Skagerrak with Z15, 3xML and 4xMS.
06-07 Apr 44: Laid the Katzbach B defensive mine barrage west of the Skagerrak with Z15, 3xML and 4xMS.
14-15 Apr 44: Laid the Leipzig defensive mine barrage west of the Skagerrak with Z15, 3xML and 4xMS.
25-26 Apr 44: Laid the Ligny defensive mine barrage west of the Skagerrak with Z15, 3xML and 4xMS. During her five months at Horten Z10 also escorted convoys bound for Norway and worked with the 1st S-Boat training FLOT.
End of Apr 44: Returned to Germany for refit.
18 Feb 45: Returned to service.
05 May 45: Z10 with a force including Z6, Z14, Z25, T17, T19, T23, T28, T35 and four smaller warships embarked 45,000 refugees from Hela. Soviet torpedo boat sortied from Kolberg against the German force, but they are repelled. The force proceeded to Copenhagen where the refugees were disembarked.
07 May 45: Z10 with Z6, Z14, Z20, Z25, Z38, Z39, T17, T19, T23, T28, T33 returned to Hela where they took off another 20,000 evacuees. These are offloaded in Glucksburg on 09 May.
Z10 was awarded to the United Kingdom as a war reparation. She was originally used as an instructional hulk to train engineering personnel in the working of the high-pressure boiler system. Her last German crew member remained with her in this capacity until November, 1946. She then was used as an accommodation ship in Southhamption. She was broken up at T. Young in Sunderland beginning 17 July, 1949.
