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.
HMS Onslow was an O-class destroyer of the Royal Navy. The O-class were intermediate destroyers, designed before the outbreak of the Second World War to meet likely demands for large number of destroyers. They had a main gun armament of four 4.7 in guns, and had a design speed of 36 kn. Onslow was ordered on 2 October 1939 and was built by John Brown & Company at their Clydebank, Glasgow shipyard, launching on 31 March 1941 and completing on 8 October 1941.
Operation Dervish was the first of the Arctic Convoys of the Second World War by which the Western Allies supplied material to the Soviet Union against Nazi Germany. Included in the convoy was the personnel and equipment of an RAF Wing, for the air defence of the Russian ports, several civilians and diplomatic missions.
Convoy PQ 1 was the first of the Arctic Convoys of the Second World War to have the code prefix PQ, which was chosen from the initials of Commander Phillip Quellyn Roberts, an operations officer in the Admiralty. The Western Allies used the Arctic route to supply the Soviet Union after the beginning of Operation Barbarossa, the German invasion, which began on 22 June 1941.
Convoy PQ 2 was the third of the Arctic Convoys of the Second World War by which the Western Allies supplied the Soviet Union after Operation Barbarossa, the German invasion, which began on 22 June 1941. The convoy sailed from Scapa Flow and arrived safely at Archangelsk.
Convoy ON 154 was a North Atlantic convoy of the ON convoys which ran during the battle of the Atlantic in the Second World War. It was the 154th of the numbered series of merchant ship convoys Outbound from the British Isles to North America. It came under attack in December 1942 and lost 13 of its 50 freighters; one U-boat was sunk.
Convoy PQ 6 was the seventh of the Arctic convoys of World War II by which the Western Allies supplied material aid to the Soviet Union in its fight with Nazi Germany. The convoy sailed from Hvalfjörður, Iceland, on 8 December 1941 and arrived at Murmansk on 20 December 1941.
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 Convoy PQ 19.
Convoy PQ 18 was an Arctic convoy of forty Allied freighters from Scotland and Iceland to Arkhangelsk in the Soviet Union during the Second World War. 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 were 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. The German B-Dienst code-breakers read some British signals and the Luftwaffe used the lull in convoys after Convoy PQ 17 to prepare a maximum effort with the Kriegsmarine.
Convoy PQ 15 was an Arctic convoy sent from Iceland by the Western Allies to aid the Soviet Union during the Second World War. The convoy sailed in late April 1942, reaching the Soviet northern ports after air attacks that sank three ships out of twenty-five.
Convoy PQ 14 was an Arctic convoy sent from Britain by the Western Allies to aid the Soviet Union during the Second World War. Convoys from Britain had been despatched since August 1941 and advantage had been taken of the perpetual darkness of the Arctic winter. German operations against the convoys had been muted due to the need to support Operation Barbarossa, confidence in imminent victory and the small size of the convoys. In late 1941 and early 1942 the Luftwaffe and Kriegsmarine had reinforced Norway with aircraft and ships.
Convoy PQ 12 was an Arctic convoy sent from Reykjavík in Iceland by the Western Allies to aid the Soviet Union during the Second World War. It sailed 1 March 1942, reaching Murmansk on 12 March 1942 for no losse despite a sortie against it by the Tirpitz.
Convoy PQ 11 was an Arctic convoy sent from Britain by the Western Allies to aid the Soviet Union during the Second World War. The voyage took place amidst storms, fog and the almost permanent darkness of the Arctic winter. The convoy was not found by German U-boats or reconnaissance aircraft from Norway and reached at Murmansk without loss.
Convoys PQ 9/10 was an Arctic convoy sent from Britain via Iceland by the Western Allies to aid the Soviet Union during the Second World War. The departure of Convoy PQ 9 on 17 January had been delayed after the Admiralty received reports of a sortie by the German battleship Tirpitz.
Convoy PQ 8 was an Arctic convoy of the Western Allies to aid the Soviet Union during the Second World War. The convoy left Iceland on 8 January 1942. On 12 January the convoy had to turn south to avoid ice; the weather was calm, visibility was exceptional, with a short period of twilight around noon. and arrived in Murmansk nine days later.

Convoy QP 11 was an Arctic Convoy of World War II, made up of merchant ships returning from the Soviet Union to Britain after delivering their cargo to the Soviet Union. The convoy consisted of 13 merchant ships, escorted by 18 warships. The convoy was attacked by German destroyers and submarines, suffering the loss of one merchant ship as well as the light cruiser HMS Edinburgh. The Germans lost the destroyer Z7 Hermann Schoemann.
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 1 was the first of the Arctic Convoys of the Second World War by which the Allies brought back ships that begun carrying supplies to the Soviet Union after Operation Barbarossa, the German invasion of 22 June 1941. The convoy sailed from Murmansk and arrived safely at Scapa Flow in Orkney.
