Operation Zarin ( English: Tsarina [Unternehmen Zarin]) was a German minelaying operation off the north-western coast of the islands of Novaya Zemlya in the Arctic Ocean. The operation was conducted between 24 September and 28 September 1942 by the German heavy cruiser Admiral Hipper escorted by the destroyers Z23, Z28, Z29 and Z30, because the British had sunk the specialist minelayer Ulm [ de ] on 25 August. The mines laid during the operation had little effect.

Background

Operation Tsar (Unternehmen Zar)

During Convoy PQ 17 (27 June – 10 July 1942) freighters sailed as far north as possible and used the coasts of Novaya Zemlya as cover to get to Murmansk or Arkhangelsk. In Operation Tsar (Unternehmen Zar) the minelayer Ulm [ de ] was sent from Kiel to Narvik escorted by the destroyer Z23 and the torpedo boats T9 and T12 from 15 to 19 August. Ulm was to lay a minefield off Cape Zhelania, the most northerly point of Novaya Zemlya, after the completion of Operation Wonderland ( Unternehmen Wunderland 16 August – 5 October 1942). The minefield would force Allied ships to steer more to the south and bring them into the range of the German bomber aircraft stationed in Norway. The sortie by Ulm was uncovered by the British Enigma machine code-breakers of the Government Code and Cypher School on 25 August.^[1] Mines were to be laid by U-boats as part of Unternehmen Zar off the narrow Matochkin Strait between Severny Island and Yuzhny Island of Novaya Zemlya in Operation Peter (Unternehmen Peter) by U-589. In Operation Paul (Unternehmen Paul) U-591 was to mine the Yugorsky Strait, the sound between the Kara Sea and the Pechora Sea.^[2]^[3]

Sinking of Ulm

The US heavy cruiser USS Tuscaloosa, with two US and three British destroyer escorts, had delivered the ground crews and equipment for Operation Orator, then sailed from the Soviet Union on 24 August and after picking up survivors from Convoy PQ 17 were in the Barents Sea. The Admiralty ordered the commander of HMS Onslaught to detach from Tuscaloosa with Marne and Martin and steer south-east of Bear Island, later altered to south towards the North Cape. Selby was told that light warships were thought to be in the area.^[4]^{[lower-alpha 1]} At 9:55 p.m. a ship was sighted and the destroyers accelerated to 25 kn (46 km/h; 29 mph), the ship turned to port until sailing away from the destroyers; six minutes afterwards, Onslaught began to fire at 9,000 yd (5.1 mi; 8.2 km), Marne following suit. Ulm turned west, then to the south-west, beginning to zigzag.^[5]

Kapitänleutnant der Reserve Ernst Biet, the German captain, ordered fire to be opened with the 105 mm gun. Marne and Martin straddled Ulm with shells and Ulm hit Marne on Y gun, killing a member of the crew and three of the survivors from PQ 17, wounding five more. By 10:16 p.m. the range had reduced to 2,500 yd (2,300 m) and the anti-aircraft guns of the destroyers were used to fire at the bridge of the German ship, to hit the wireless room and any fire-control apparatus. The automatic fire caused many casualties as much of the crew had gathered there, ready to abandon ship. Onslaught was endangered by the fall of shot from Marne and increased speed to 30 kn (35 mph; 56 km/h) to get out of the way. Onslaught missed with two torpedoes but hit Ulm near the foremast at 10:31 p.m. setting off a big explosion and detonating ammunition, breaking Ulm in two, the halves sinking quickly at 10:35 p.m.Marne rescued 54 survivors but abandoned 30 to 40 men to die, apparently due to the presence of German aircraft; 132 men were killed.^[6] The loss of Ulm greatly diminished the German ability to lay large quantities of mines in the Arctic.^[7]

Operation Tsarina (Unternehmen Zarin)

The sinking of Ulm forced the Germans to improvise by using the heavy cruiser Admiral Hipper as a substitute, to lay the minefield off the islands of Novaya Zemlya in Unternehmen Zarin (Operation Tsarina).^[7] The operation was commanded by Vice Admiral Oskar Kummetz and due to commence on 23 September. Admiral Hipper ( Konteradmiral [Rear-Admiral] Wilhelm Meisel), with 96 naval mines on deck, was to sail from Altafjord escorted by the destroyers Z23, Z28, Z29 and Z30.^[3]

Sortie

On 24 September, Admiral Hipper sailed with its four destroyer escorts, present until the morning of 26 September. In the evening the minefield was laid on the north-west coast of Novaya Zemlya.^[3]Admiral Hipper picked up radio traffic from ships nearby and Meisel wanted to investigate but Kummetz was more prudent and returned to the destroyers. The flotilla arrived back at Kaafjord on 28 September.^[8]

Aftermath

A Swedish source, known as agent A 2, who worked for the British Naval Attaché in Stockholm and Enigma decrypts warned the Admiralty that another operation against an Arctic convoy by U-boats, ships and aircraft was being prepared. On 5 August, due to a false alarm from a U-boat, the cruiser Köln had been sent north from Trondheim to join Tirpitz, Admiral Scheer, and Admiral Hipper around Narvik. The Luftwaffe in Northern Norway had been reinforced by about thirty Ju 88 torpedo-bombers. The threat of another operation against an Allied convoy had been considered serious by the British until the end of September. Enigma decrypts had not given the British warning of the sortie by Hipper and a report from agent A 2 that Admiral Hipper had sailed on 24 September was not received by the Admiralty until 27 September. No ships are known to have run into the minefield.^[7]^{[lower-alpha 2]}

Notes

↑ The decision to send orders to ship commanders ignorant of Enigma decodes was unusual.^[1]
↑ Operation Peter took place on 28 August and Paul was called off. The Russian patrol ship SKR-23/Musson was sunk on 11 October and the merchant ship Shchors (3,770 gross register tons) was mined and sunk of the Yugorsky Strait on 14 October.^[2]^[3]

PQ 17 was the code name for an Allied Arctic convoy during the Second World War. On 27 June 1942, the ships sailed from Hvalfjörður, Iceland, for the port of Arkhangelsk in the Soviet Union. The convoy was located by German forces on 1 July, after which it was shadowed continuously and attacked. The First Sea Lord Admiral Dudley Pound, acting on information that German ships, including the German battleship Tirpitz, were moving to intercept, ordered the covering force based on the Allied battleships HMS Duke of York and USS Washington away from the convoy and told the convoy to scatter. Because of vacillation by Oberkommando der Wehrmacht, the Tirpitz raid never materialised. The convoy was the first large joint Anglo-American naval operation under British command; in Churchill's view this encouraged a more careful approach to fleet movements.

The Arctic convoys of World War II were oceangoing convoys which sailed from the United Kingdom, Iceland, and North America to northern ports in the Soviet Union – primarily Arkhangelsk (Archangel) and Murmansk in Russia. There were 78 convoys between August 1941 and May 1945, sailing via several seas of the Atlantic and Arctic oceans, with periods with no sailings during several months in 1942, and in the summers of 1943 and 1944.

The Battle of the Barents Sea was a World War II naval engagement on 31 December 1942 between warships of the German Navy (Kriegsmarine) and British ships escorting convoy JW 51B to Kola Inlet in the USSR. The action took place in the Barents Sea north of North Cape, Norway. The German raiders' failure to inflict significant losses on the convoy infuriated Hitler, who ordered that German naval strategy would henceforth concentrate on the U-boat fleet rather than surface ships.

Admiral Hipper was the lead ship of the Admiral Hipper class of heavy cruisers which served with Nazi Germany's Kriegsmarine during World War II. The ship was laid down at the Blohm & Voss shipyard in Hamburg in July 1935 and launched February 1937; Admiral Hipper entered service shortly before the outbreak of war, in April 1939. The ship was named after Admiral Franz von Hipper, commander of the German battlecruiser squadron during the Battle of Jutland in 1916 and later commander-in-chief of the German High Seas Fleet. She was armed with a main battery of eight 20.3 cm (8 in) guns and, although nominally under the 10,000-long-ton (10,160 t) limit set by the Anglo-German Naval Agreement, actually displaced over 16,000 long tons (16,260 t).

Convoy PQ 18 was an Arctic convoy of forty Allied freighters from Scotland and Iceland to Arkhangelsk in the Soviet Union in the war against Nazi Germany. The convoy departed Loch Ewe, Scotland on 2 September 1942, rendezvoused with more ships and escorts at Iceland and arrived at Arkhangelsk on 21 September. An exceptionally large number of escorts was provided by the Royal Navy in Operation EV, including the first escort carrier to accompany an Arctic convoy. Detailed information on German intentions was provided by the code breakers at Bletchley Park and elsewhere, through Ultra signals decrypts and eavesdropping on Luftwaffe wireless communications.

Operation Wonderland was an operation from 16 to 30 August 1942 by the Kriegsmarine in the Barents Sea and the Kara Sea off the Arctic coast of the Soviet Union. The operation was an attack on Soviet shipping using the Northern Sea Route which ran along the Soviet Arctic coast from the Bering Strait, westwards along Siberia to the Kara Sea. The operation was the first part of a campaign to dominate the seas of the western Arctic. Reports from Japanese naval intelligence alerted the Germans to the sailing of a convoy, EON-18.

Unternehmen Rösselsprung was a plan by the German Navy to intercept an Arctic convoy in mid-1942. It was the largest operation of its type mounted by the Kriegsmarine and resulted in the near-destruction of Convoy PQ 17. The success of the operation was indirect none of the ships engaged the convoy, its losses inflicted by U-boat and aircraft attacks. Despite not making contact with the convoy a number of the ships of Unternehmen Rösselsprung were damaged and the heavy cruiser German cruiser Lützow (1940), ran aground in thick fog, needing three months of repairs.

Operation FB took place as part of the Arctic Convoys of the Second World War. The operation consisted of independent sailings by unescorted merchant ships between Iceland and Murmansk. In late 1942, the Allies had taken the offensive against Germany but the dispatch of supplies to the USSR by convoy via the Arctic route was suspended, due to the demands of the Mediterranean campaign. Convoy PQ 19 was cancelled because the Home Fleet diverted ships to the Mediterranean for Operation Torch which would have had to be postponed for three weeks had ships been provided for PQ 19.

Convoy PQ 17 was the penultimate of the PQ/QP series of arctic convoys, bound from British ports through the Arctic Ocean via Reykjavík to the White Sea ports of the Soviet Union, particularly Murmansk and Archangel. The convoy was heavily defended, but fearing an imminent attack by substantial German surface forces, the Admiralty made the decision to disperse the convoy.

Operation Doppelschlag was a German plan for a sortie in 1942 during the Second World War into the Arctic Ocean by the Kriegsmarine. The operation followed Operation Rösselsprung, against Convoy PQ 17 in July 1942 to attack convoy PQ 18 the next Arctic convoy of the Western Allies.

The German destroyer Z4 Richard Beitzen was one of four Type 1934 destroyers built for the German Navy (Kriegsmarine) during the mid-1930s. Completed in 1937, the ship spent most of her time training although she did participate in the occupation of Memel in early 1939. At the beginning of World War II in September 1939, the ship was initially deployed to blockade the Polish coast, but was soon transferred to the Kattegat where she inspected neutral shipping for contraband goods. In late 1939 and early 1940, the ship laid two offensive minefields off the English coast that claimed 17 merchant ships. Z4 Richard Beitzen was in reserve during the Norwegian Campaign of early 1940 and was transferred to France later that year, where she made several attacks on British shipping.

Z16 Friedrich Eckoldt was a Type 1934A-class destroyer built for Nazi Germany's Kriegsmarine in the late 1930s. It was named after Kapitänleutnant Friedrich Eckoldt (1887–1916), the commander of torpedo boat V 48, who was killed when his boat was sunk during the Battle of Jutland on 31 May 1916.

Z23 was one of fifteen Type 1936A destroyers built for the Kriegsmarine during World War II. Completed in 1940, the ship spent the war in Norwegian and French waters, escorting German ships and occasionally engaging Allied warships. In early 1941 she escorted ships between the Baltic and southern Norway before spending four months protecting ships as they transited through the Bay of Biscay. A few months after the Operation Barbarossa began in June, Z23 was transferred to northern Norway where she attempted to intercept one of the Arctic convoys returning from the Soviet Union and helped to lay several minefields.

Z27 was one of fifteen Type 1936A destroyers built for the Kriegsmarine during World War II. Completed in 1941, the ship was transferred to Norwegian waters later that year where she remained for most of the next several years, escorting convoys and laying minefields. She sank a Soviet oil tanker in late 1942 before sailing to Germany for a refit. Upon its completion in mid-1943, Z27 returned to Norway and participated in Operation Zitronella, the raid on the island of Spitsbergen in September.

Z28 was one of fifteen Type 1936A destroyers built for the Kriegsmarine during World War II. Built as a flotilla leader with fewer guns than her sister ships, she was completed in 1941. The ship spent most of the first few years of her service in Norwegian waters, escorting convoys and laying minefields. Z28 ran aground in early 1943 and spent the rest of the year under repair. The ship briefly returned to Norway at the beginning of 1944, but was transferred to the Baltic shortly afterwards to support minelaying operations in the Gulf of Finland. That was her primary focus through July and then she began escorting German cruisers as they bombarded Soviet troops ashore in addition to German convoys evacuating people from Finland and the Baltic States.

Z29 was one of fifteen Type 1936A destroyers built for the Kriegsmarine during World War II. Completed in 1941, she took part in the Channel Dash in early 1942 as flagship of the escort force. Despite this venture to France, the ship spent most of the war in Norwegian waters, escorting German ships and laying minefields. Z29 participated in the indecisive Battle of the Barents Sea at the end of the year, during which she helped to sink a British minesweeper. The ship was damaged during the raid on the island of Spitsbergen in September 1943. Z29 was damaged by British aircraft attacking the battleship Tirpitz in July 1944. The ship escorted troop convoys from northern Norway when the Germans began evacuating the area beginning in October until she began an extensive refit in December.

Z30 was one of fifteen Type 1936A destroyers built for the Kriegsmarine during World War II. Completed in 1941, the ship was transferred to Norwegian waters in early 1942 where she remained for most of the rest of her career, escorting convoys and laying minefields. She played a minor role in the indecisive Battle of the Barents Sea at the end of the year and was damaged during the raid on the island of Spitsbergen in September 1943.

Convoy QP 14 was an Arctic convoy of the QP series which ran during the Second World War. The convoy was a return journey of Allied ships from the port of Archangelsk in the Soviet Union to Loch Ewe in the west of Scotland. The British planned to send Convoy PQ 18 from Iceland to Murmansk and when the convoys crossed transfer much of the escort force from the outbound convoy to Convoy QP 14 and escort back it through the most dangerous waters off Norway.

Convoy QP 13 was an Arctic convoy of the PQ/QP series which ran during the Second World War. It was the thirteenth of the numbered series of convoys of merchant ships westbound from the Arctic ports of Arkhangelsk and Murmansk to the United Kingdom, Iceland, and North America.

Operation Orator was the code name for the defence of the Allied Arctic convoy PQ 18 by British and Australian air force units, based temporarily in North-West Russia, against attack by the German battleship Tirpitz and other Kriegsmarine surface vessels. The wing, known as the Search & Strike Force, was commanded by Group Captain Frank Hopps and its maritime strike element was the Leuchars Wing, comprising No. 144 Squadron, Royal Air Force (RAF) and No. 455 Squadron, Royal Australian Air Force (RAAF) equipped with Handley-Page Hampden TB 1 torpedo bombers.
