Operation Zarin

Operation Zarin ( en, Tsarina []) was a German Naval mine, 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 escorted by the destroyers , , and , because the British had sunk the specialist minelayer ' on 25 August. The mines laid during the operation had little effect.

Background

Operation Tsar ()

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 () the minelayer ' was sent from Kiel to Narvik escorted by the destroyer and the torpedo boats and from 15 to 19 August. ''Ulm'' was to lay a minefield off Cape Zhelaniya, the most northerly point of Novaya Zemlya, after the completion of Operation Wonderland ( 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. Mines were to be laid by U-boats as part of off the narrow Matochkin Strait between Severny Island and Yuzhny Island of Novaya Zemlya in Operation Peter () by U-589. In Operation Paul () U-591 was to mine the Yugorsky Strait, the sound between the Kara Sea and the Pechora Sea.

Sinking of ''Ulm''

The US heavy cruiser , 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 to detach from ''Tuscaloosa'' with and 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. At a ship was sighted and the destroyers accelerated to , the ship turned to port until sailing away from the destroyers; six minutes afterwards, ''Onslaught'' began to fire at , ''Marne'' following suit. ''Ulm'' turned west, then to the south-west, beginning to zigzag.

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 the range had reduced to 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 to get out of the way. ''Onslaught'' missed with two torpedoes but hit ''Ulm'' near the foremast at setting off a big explosion and detonating ammunition, breaking ''Ulm'' in two, the halves sinking quickly at ''Marne'' rescued 54 survivors but abandoned 30 to 40 men to die, apparently due to the presence of German aircraft; 132 men were killed. The loss of ''Ulm'' greatly diminished the German ability to lay large quantities of mines in the Arctic.

Operation Tsarina ()

The sinking of ''Ulm'' forced the Germans to improvise by using the heavy cruiser as a substitute, to lay the minefield off the islands of Novaya Zemlya in (). The operation was commanded by Vice Admiral Oskar Kummetz and due to commence on 23 September. ''Admiral Hipper'' ( ear-AdmiralWilhelm Meisel), with 96 naval mines on deck, was to sail from Altafjord escorted by the destroyers , , and .

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. ''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.

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 had been sent north from Trondheim to join , , 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.
