Convoy QP 14 (13–26 September 1942) 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 Arkhangelsk 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.
Rather than provide a covering force of cruisers and a distant covering force of battleships and aircraft carriers as hitherto, a large Fighting Destroyer Escort was formed to accompany Convoy PQ 18 and be capable of independently operating, to present an attack by German ships with the risk of massed torpedo salvoes. To keep the larger number of escorts fuelled, Force P of fuel tankers with escorts were sent to Svalbard and fleet oilers joined Convoy PQ 18; on 16 September, much of the Convoy PQ 18 escort force and oilers transferred to Convoy QP 14 as the convoys crossed.
There was a scare on 19 September that German ships were attacking, but this was a false alarm, and the convoy was opposed only by aircraft and submarines. The German attacks sank three merchant ships and two of the escorts for the loss of a U-boat and five damaged, the aircraft on the escort carrier doing much to deter U-boat attacks, assisted by land-based aircraft from 23 September. The convoy reached Loch Ewe in Scotland on 26 September.
Operation EV, the escort operation for Convoy QP 14 and Convoy PQ 18, was judged a success by its commander, Rear-Admiral Robert Burnett. He noted that the risks had been great and had re-fuelling not being achieved due to bad weather or if there had been better co-ordination between U-boats and Luftwaffe aircraft, there could have been another disaster like Convoy PQ 17. Burnett was criticised by Stephen Roskill, the official historian, for sending Avenger back to base on 20 September; weather grounded the land-based aircraft and three ships were sunk on 22 September but in 2004, Richard Woodman wrote that the risks to Convoy QP 14 had been justified.
Background
Arctic Ocean
Between Greenland and Norway are some of the most stormy waters of the world's oceans, of water under gales full of snow, sleet and hail. Around the North Cape and the Barents Sea the sea temperature rarely rises about 4° Celsius and a man in the water will probably die unless rescued immediately. The cold water and air makes spray freeze on the superstructure of ships, which has quickly to be removed to avoid the ship becoming top-heavy. The cold Arctic water is met by the Gulf Stream, a flow of warm water from the Gulf of Mexico, which becomes the North Atlantic Drift further north. Arriving at the south-west of England the drift moves between Scotland and Iceland. North of Norway the drift splits.
The northern stream of the drift goes north of Bear Island to Svalbard and the southern stream follows the coast of Murmansk into the Barents Sea. The mingling of cold Arctic water and warmer water of higher salinity generates thick banks of fog for convoys to hide. The waters drastically reduced the effectiveness of Asdic as U-boats moved in waters of differing temperatures and density. In winter, polar ice can form as far south as off the North Cape, forcing ships closer to Luftwaffe air bases and in summer it can recede to Svalbard, allowing ships to sail further out to sea. The area is in perpetual darkness in winter and permanent daylight in the summer which makes visual air reconnaissance almost impossible or easy.
Arctic convoys
In October 1941, after Operation Barbarossa, the German invasion of the USSR, which had begun on 22 June, the Prime Minister, Winston Churchill, made a commitment to send a convoy to the Arctic ports of the USSR every ten days and to deliver a month from July 1942 to January 1943, followed by and another more than already promised.The first convoy was due at Murmansk around 12 October and the next convoy was to depart Iceland on 22 October. A motley of British, Allied and neutral shipping loaded with military stores and raw materials for the Soviet war effort would be assembled at Hvalfjordur (Hvalfiord) in Iceland, convenient for ships from both sides of the Atlantic.
By late 1941, the convoy system used in the Atlantic had been established on the Arctic run; a convoy commodore ensured that the ships' masters and signals officers attended a briefing before sailing to make arrangements for the management of the convoy, which sailed in a formation of long rows of short columns. The commodore was usually a retired naval officer, aboard a ship identified by a white pendant with a blue cross. The commodore was assisted by a Naval signals party of four men, who used lamps, semaphore flags and telescopes to pass signals, coded from books carried in a bag, weighted to be dumped overboard. In large convoys, the commodore was assisted by vice- and rear-commodores who directed the speed, course and zig-zagging of the merchant ships and liaised with the escort commander.
Following Convoy PQ 16 and the disaster to Convoy PQ 17 in July 1942, Arctic convoys were postponed for nine weeks and much of the Home Fleet was detached to the Mediterranean for Operation Pedestal, a Malta convoy. During the lull, Admiral John Tovey concluded that the Home Fleet had been of no great protection to convoys beyond Bear Island, midway between Spitsbergen and the North Cape. Tovey would oversee the operation from Scapa Flow, where the fleet was linked to the Admiralty by landline, immune to variations in wireless reception. The next convoy should be accompanied by sufficient protection against surface attack; the longer-range destroyers of the Home Fleet could be used to augment the close escort force of anti-submarine and anti-aircraft ships, to confront a sortie by German ships with the threat of a massed destroyer torpedo attack. The practice of meeting homeward-bound QP convoys near Bear Island was dispensed with and Convoy QP 14 was to wait until Convoy PQ 18 was near its destination, despite the longer journey being more demanding of crews, fuel and equipment. The new escort carrier (Commander Anthony Colthurst) had arrived from the United States and was added to the escort force, to give the convoy air cover.
Signals intelligence
Bletchley Park
The British Government Code and Cypher School (GC&CS) based at Bletchley Park housed a small industry of code-breakers and traffic analysts. By June 1941, the German Enigma machine Home Waters () settings used by surface ships and U-boats could quickly be read. On 1 February 1942, the Enigma machines used in U-boats in the Atlantic and Mediterranean were changed but German ships and the U-boats in Arctic waters continued with the older ( from 1942, Dolphin to the British) settings. By mid-1941, British Y-stations were able to receive and read Luftwaffe W/T transmissions and give advance warning of Luftwaffe operations. In 1941, naval Headache personnel with receivers to eavesdrop on Luftwaffe wireless transmissions were embarked on warships and from May 1942, ships gained RAF Y computor parties, which sailed with cruiser admirals in command of convoy escorts, to interpret Luftwaffe W/T signals intercepted by the Headaches. The Admiralty sent details of Luftwaffe wireless frequencies, call signs and the daily local codes to the computors, which combined with their knowledge of Luftwaffe procedures, could glean fairly accurate details of German reconnaissance sorties. Sometimes computors predicted attacks twenty minutes before they were detected by radar.
The rival German (, Observation Service) of the (MND, Naval Intelligence Service) had broken several Admiralty codes and cyphers by 1939, which were used to help ships elude British forces and provide opportunities for surprise attacks. From June to August 1940, six British submarines were sunk in the Skaggerak using information gleaned from British wireless signals. In 1941, read signals from the Commander in Chief Western Approaches informing convoys of areas patrolled by U-boats, enabling the submarines to move into "safe" zones. broke Naval Cypher No 3 (the convoy cypher) in February 1942 and by March was reading up to 80 per cent of the traffic, which continued until 15 December 1943. By coincidence, the British lost access to the Shark cypher and had no information to send in Cypher No 3 which might compromise Ultra. In early September, Finnish Radio Intelligence deciphered a Soviet Air Force transmission which divulged the convoy itinerary, which was forwarded it to the Germans.
Prelude
In March 1942, Adolf Hitler issued a directive for a greater anti-convoy effort to weaken the Red Army and prevent Allied troops being transferred to northern Russia, preparatory to a landing on the coast of northern Norway. ( Hans-Jürgen Stumpff) was to be reinforced and the was ordered to put an end to Arctic convoys and naval incursions. The Luftwaffe and were to work together with a simplified command structure, which was implemented after a conference; the Navy had preferred joint command but the Luftwaffe insisted on the exchange of liaison officers. was to be reinforced by 2./Kampfgeschwader 30 (KG 30) and KG 30 was to increase its readiness for operations. A squadron of (Aufkl.Fl.Gr. 125) was transferred to Norway and more long-range Focke-Wulf Fw 200 Kondor patrol aircraft from Kampfgeschwader 40 (KG 40) were sent from France. At the end of March, the air fleet was divided.
[ Alexander Holle], the largest command, was based at Kirkenes with 2./JG 5, 10.(Z)/JG 5, 1./StG 5 (Dive Bomber Wing 5) and 1. 124 [1./(F) 124] (1 Squadron, Long Range Reconnaissance Wing 124) charged with attacks on Murmansk and Arkhangelsk as well as attacks on convoys. Part of was based at Petsamo (5./JG 5, 6./JG 5 and 3./Kampfgeschwader 26 (3./KG 26), Banak (2./KG 30, 3./KG 30 and 1./(F) 22) and Billefjord (1./Kü.Fl.Gr. 125). ( Hans Roth) was based at Bardufoss but had no permanently attached units, which were added according to events. At the start of the anti-shipping campaign only the coastal patrol squadrons 3./ 906 at Trondheim and 1./1./Kü.Fl.Gr. 123 at Tromsø were attached to . was based at Sola and was responsible for the early detection of convoys and attacks south of a line from Trondheim westwards to Shetland and Iceland, with 1./(F) 22, the of 1./KG 40, short-range coastal reconnaissance squadrons 1./ 406 (1./Kü.Fl.Gr. 406), 2./ 406 (2./Kü.Fl.Gr. 406) and a weather reconnaissance squadron.
Luftwaffe tactics As soon as information was received about the assembly of a convoy, would send long-range reconnaissance aircraft to search Iceland and northern Scotland. Once a convoy was spotted aircraft were to keep contact as far as possible in the extreme weather of the area. If contact was lost its course at the last sighting would be extrapolated and overlapping sorties would be flown to regain contact. All three were to co-operate as the convoy moved through their operational areas. would begin the anti-convoy operation east to a line from the North Cape to Spitzbergen Island, whence would take over using his and 's aircraft, which would to Kirkenes or Petsamo to stay in range. was not allowed to divert aircraft to ground support during the operation. As soon as the convoy came into range, the aircraft were to keep up a continuous attack until the convoy docked at Murmansk or Arkhangelsk. From late March to late May the air effort against Convoy PQ 13, Convoy PQ 14, Convoy PQ 15 and Convoy QP 9, Convoy QP 10 and Convoy QP 11 had little effect, twelve sinkings out of 16 lost in PQ convoys and two out of five sinkings from QP convoys being credited to the Luftwaffe; 166 merchant ships had sailed for Russia and 145 had survived the journey.
