Convoy PQ 18

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.

The German '' B-Dienst'' read some British signals and ''Luftwaffe'' used the lull in convoys after Convoy PQ 17 (27 June – 10 July) to prepare a maximum effort with the '' Kriegsmarine''. From 12 to 21 September PQ 18 was attacked by bombers, torpedo-bombers, U-boats and mines, which sank thirteen ships at a cost of forty-four aircraft and four U-boats. The convoy was defended by escort ships and the aircraft of the escort carrier which used signals intelligence gleaned from Ultra and ''Luftwaffe'' wireless frequencies to provide early warning of some air attacks and to attempt evasive routeing of the convoy around concentrations of U-boats. United States Navy Armed Guard and British Naval and Royal Artillery Maritime Regiment gunners were embarked on the freighters to operate anti-aircraft guns and barrage balloons, which made air attacks more difficult and because of inexperience, occasionally wounded men and damaged ships and cargo, with wild shooting.

The convoy handed over its distant escorts and ''Avenger'' to the homeward bound Convoy QP 14 near Archangelsk on 16 September and continued with the close escort and local escorts, riding out a storm in the Northern Dvina estuary and the last attacks by the ''Luftwaffe'', before reaching Archangelsk on 21 September. Several ships ran aground in the storm but all were eventually refloated; unloading the convoy took a month. Because of its losses and the transfer in November of its most effective remaining aircraft to the Mediterranean to oppose Operation Torch, the ''Luftwaffe'' effort could never be repeated.

Background

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, 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 QP 14 was to wait until PQ 18 was near its destination, despite the longer journey being more demanding of crews, fuel and equipment. The new escort carrier (Commander A. P. 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 (''Heimish'') 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 ''Heimish'' (''Hyrda'' from 1942, Dolphin to the British). 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.

B-Dienst

The rival German ''Beobachtungsdienst'' (''B-Dienst'', Observation Service) of the '' Kriegsmarine'' ''Marinenachrichtendienst'' (''MND'', Naval Intelligence Service) had broken several Admiralty codes and cyphers by 1939, which were used to help ''Kriegsmarine'' 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, ''B-Dienst'' 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. ''B-Dienst'' had broken Naval Cypher No 3 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

Operation Orator

An anti-shipping force (Group Captain F. L. Hopps) for the Barents Sea comprising 32 Handley Page Hampden torpedo-bombers from 144 Squadron, Royal Air Force (RAF) and 455 Squadron, Royal Australian Air Force (RAAF) nine Catalina maritime patrol aircraft from 210 Squadron RAF and three photo reconnaissance Spitfires from the RAF Photographic Reconnaissance Unit, was sent to the Soviet Union to oppose an attack by a group of German surface ships assembled in Norwegian waters, which included the battleship ''Tirpitz''. On 13 August the cruiser , two US and one British destroyer sailed for Russia, with RAF ground crews for the Hampden squadrons and a medical unit. The Catalinas were to be based at Grasnaya on the Kola Inlet and the Hampdens and Spitfires at Vaenga.

The Catalinas had to remain on operations until the last minute, which meant that their equipment and ground crews also had to travel by air. The relatively short range of the Hampdens and the limited navigational equipment on board and the weather caused the loss of several Hampdens and others were shot down en route. Six bombers crashed in Sweden or German-occupied Norway and plans for PQ 18 and QP 14 were recovered by the Germans from one of the aircraft. Two Hampdens ran out of fuel and force-landed in Russia, one a write-off; one aircraft arrived over the Kola Inlet during an air raid and was shot down into the sea by Russian fighters. The aircraft sank with the wounded air gunner on board and the rest of the crew were strafed in the sea. The survivors managed to get ashore, where they came under small-arms fire, until their cries of "Angliski" were recognised. By 5 September, 24 Hampdens had reached Vaenga.

Operation EV

Operation EV was the code-name for a naval operation to escort Convoy PQ 18 to a rendezvous with the returning Convoy QP 14 and hand over PQ 18 to British and Soviet escorts from Archangelsk. The convoy consisted of forty merchant ships including the Catapult Armed Merchant ship (CAM Ship) ''Empire Morn'' carrying a Hawker Hurricane Mk I fighter and the convoy rescue ship SS ''Copeland''. The Convoy Commodore, Rear-Admiral (retired) Edye Boddam-Whetham RNR, was in ''Temple Arch''. Three minesweepers to be based in Russia accompanied the convoy along with Force Q, two Royal Fleet Auxiliary (RFA) oilers and . A Close Escort (Commander A. B. Russell) was led by the destroyer , with two destroyers and two anti-aircraft ships, four Flower-class corvettes, four anti-submarine trawlers, three minesweepers and two submarines.

The Carrier Force comprised ''Avenger'' with 802 Naval Air Squadron and 882 Naval Air Squadron Fleet Air Arm (six Hawker Sea Hurricane fighters each) and 825 Naval Air Squadron (three Fairey Swordfish reconnaissance and torpedo-bombers, shared by five crews) and three destroyers. A Fighting Destroyer Escort (FDE) of the cruiser (Rear Admiral Robert Burnett) and sixteen fleet destroyers were disposed in Force A aptain (D) H. T. Armstrongin and Force B aptain (D) I. M. R. Campbellin . The Spitzbergen Fuelling Force (Force P) departing ahead of the convoy on 3 September was made up of two RFA oilers and four destroyers, bound for Lowe Sound. Spitzbergen was the Dutch name of the islands (Jagged Mountains) until 1925, when they became Svalbard (Norwegian) in the Svalbard Treaty. The summer melt of the polar ice cap meant that the convoy could sail north of Bear Island, considerably lengthening the journey and to conserve fuel, destroyer attacks on U-boats were limited to 90 minutes' duration.

Vice-Admiral Stuart Bonham Carter commanded a Cruiser Covering Force (CCF) comprising three cruisers and a concurrent supply run was to be made to Svalbard by two cruisers and a destroyer. A Distant Covering Force (Vice Admiral Bruce Fraser) with the battleships and , the cruiser and five short-range destroyers, was to sail from Akureyri on the north Icelandic coast. Four submarines took station off the Lofoten Islands and three off north Norway. The convoy was to be escorted by Western Approaches Command from its departure Loch Ewe in Scotland on 2 September to the Denmark Strait by seven destroyers and five trawlers until a handover on 7 September. Four Soviet destroyers with four British corvettes and three minesweepers were to rendezvous with the convoy near Archangelsk.

''Marinegruppenkommando Nord''

On 24 June, a British minesweeper based at Kola was sunk by Ju 87 ''Stuka'' dive-bombers and on 16 August, ''Admiral Scheer'' conducted ''Unternehmen Wunderland'', a sortie against Russian ships thought to be sailing along the route north of Siberia. ''Admiral Scheer'' sailed north of Novaya Zemlya and then to the east and sank a Soviet icebreaker. By 30 August ''Admiral Scheer'' was back in Narvik. ''B-Dienst'' signals interception and documents recovered from a crashed Hampden, revealed details about the PQ 18 and QP 14 convoys, including their crossover and escort changeover points. U-boats, destroyers and the minelayer ''Ulm'' sailed on Operation Zar (''Unternehmen Zar'') to sow mines at the entrance of the White Sea and off Novaya Zemlya.

On 25 August, Ultra revealed the itinerary of ''Ulm'' and the destroyers (, and ) with ''Tuscaloosa'', sailing south of Bear Island, were diverted and sank ''Ulm'' that night; sixty survivors were taken prisoner. The Germans had to press ''Admiral Hipper'' into service as a minelayer. The ''Kriegsmarine'' established a U-boat patrol group of twelve boats in the Norwegian Sea and a squadron comprising the cruisers ''Admiral Scheer'', ''Admiral Hipper'', ''Köln'' and four destroyers to attack PQ 18. Since ''Unternehmen Rösselsprung'' in the summer, the battleship ''Tirpitz'' and cruiser ''Lützow'' and three destroyers were in dock for repairs and were not available for operations.

''Luftwaffe''

The ''Luftwaffe'' used the lull after PQ 17 to assemble a force of 35 Junkers Ju 88 A-4 dive-bombers of ''Kampfgeschwader 30'' (KG 30) at Banak and 42 torpedo-bombers of '' Kampfgeschwader 26'' (KG 26) (I/KG 26 ajor Werner Klümperwith 28 Heinkel He 111 H-6s and III/KG 26 with 14 Ju 88A-4s) at Bardufoss (''Fliegerführer Lofoten'' Colonel August Roth) and Banak, with I StG 5 (Ju 87) at Kirkenes (''Fliegerführer Nordost'', Colonel Alexander Holle). The reconnaissance aircraft of ''Luftflotte 5'' (''Generaloberst'' Hans-Jürgen Stumpff) comprised I/''Seefernaufklärungsgruppe'' 406 (He 115) at Tromsø, I/''Seefernaufklärungsgruppe'' 906 (BV 138) at Stavanger, I KG 40 (Fw 200) at Trondheim, I (F)/22 and I (F)/124 (Ju 88) divided between Bardufoss, Banak and Kirkenes and ''Wettererkundungstaffel'' 6 (''Weste'' 6) at Banak.

After analysing the results of anti-shipping operations against PQ 17, in which the crews of ''Luftflotte'' 5 made exaggerated claims of ships sunk, including a cruiser, the anti-shipping units devised a new tactic called ''Goldene Zange'' (Golden Comb). Ju 88 bombers were to divert the defenders with medium and dive bombing attacks as the torpedo-bombers approached out of the twilight, flying in line abreast at wave-top height to evade radar, the convoy being silhouetted against the lighter sky, then dropping their torpedoes at the same time. When ''B-Dienst'' discovered that an aircraft carrier would accompany the next convoy, ''Reichsmarschall'' Hermann Göring gave orders that it must be sunk first; aircrew were told that the destruction of the convoy was the best way to help the German army at Stalingrad and Caucasus in southern Russia.

Convoy PQ 18

2–11 September

PQ 18 left Loch Ewe on 2 September 1942, accompanied by its Local Escort force from Western Approaches Command. The convoy ran into stormy weather, which made formation keeping much harder, particularly for some of the ships with novice crews, dubious about the British since the PQ 17 disaster. Some escorts also had inexperienced crews and ''Scylla'' and ''Avenger'' were new ships. ''Avenger'' had engine trouble, a Sea Hurricane was washed overboard and aircraft tethered below, broke free and slid around the hangar, as did fuzed bombs. The convoy was reported by U-456 and on 6 September, a Focke-Wulf Fw 200 Condor long-range reconnaissance aircraft had observed ''Avenger'' and the Close Escort Force at Seidisfiord in Iceland. The Condor identified ''Avenger'' as and near-missed with its bombs. Next day, as the convoy sailed round the south-west of Iceland, the local escort docked at Hvalfiordur and the close escort with six Soviet freighters joined the convoy, which rounded the west coast heading north. The convoy was sighted by a Condor on 8 September and then hidden by an overcast.

A Swedish source (A2) in Stockholm had told the British naval attaché that a surface ship operation would be mounted against the next convoy and by 8 September, the Admiralty could provide the escort commander a report on the positions of the twenty U-boats expected to attack the convoy and forecast that 65 torpedo-bombers (true figure 92) and 120 bombers were preparing the biggest torpedo attack on an Arctic convoy so far. On 8 September the convoy was joined by ''Scylla'', with the FDE and the ''Avenger'' carrier group, which had waited until before sailing, to conserve fuel and took post around the convoy at the same time on 9 September; the Germans sent new search positions to the U-boats and this was passed to the convoy the next day. The Cruiser Covering Force had sailed independently to a position west of Bear Island and the group carrying supplies bound for the Norwegian weather station at Barentsburg was off Svalbard, using PQ 18 to divert the ''Luftwaffe''. The battleships of the distant covering force had sailed from Seidisfiord towards Jan Mayen Island.

Contact was made by U-boats from the ''Eispalast'' wolfpack of twelve boats, which were distributed in three groups along the expected route of the convoy. On 10 September, the weather worsened and fog descended as the escorts chased Asdic reports of submarines. Off Norway, far to the east, as ''Scheer'', ''Hipper'', ''Koln'' and their destroyers began ''Unternehmen Doppelschlag''. Next day, as the convoy made its way through fog and rain squalls which turned to snow, Boddam-Whetham criticised the ships's station keeping and warned that ships should keep two cables apart bout ''Scylla'' and five destroyers of the 3rd Destroyer Flotilla from the FDE departed the convoy for ''Bellsundet'' (Bell Sound) on the south-west coast on the Svalbard and arrived at on 12 September, to fuel from the two oilers in Axelfjord; the destroyers departed at on 13 September.

12 September

Dawn on 12 September was overcast clear underneath, with a north-westerly breeze when a BV 138 dropped below the cloud. Four Sea Hurricanes took off from ''Avenger'' but failed to shoot down the shadower, which flew back into the clouds. Sea Hurricanes were armed with rifle calibre machine-guns and hits often failed to penetrate. During the day, escorts' High-frequency direction finding equipment (Huff-Duff) detected U-boat wireless transmissions and the escorts made many depth charge attacks, driving off several U-boats. In front of the convoy at the destroyer ''Faulknor'', received an Asdic echo and destroyed with its first depth charge salvo.

13 September

The convoy received Ultra information on the latest U-boat positions from the Admiralty and Swordfish aircraft were on anti-submarine patrol by dodging a BV 138 and a Ju 88, which were faster and better armed. The German aircraft disappeared into cloud when Sea Hurricanes took off from ''Avenger'', then flew back as soon as they landed. Several U-boats were forced to dive by the Swordfish but at the Russian freighter ''Stalingrad'' in the tenth column, on the right flank, was torpedoed and sunk by with 21 dead out of a complement of 87. ''Oliver Ellsworth'', following behind, turned to avoid the ship and was hit by another torpedo as the rest of PQ 18 was making the emergency turn and one man was lost. Several minesweepers and trawlers converged on the site and rescued the survivors. Sea Hurricanes were sent to attack several reported to be dropping mines ahead of the convoy but again failed to destroy them; Swordfish tried to attack U-boats on the surface only to be foiled by the Early in the afternoon, two escorts attacked with no result after a conning tower was seen and another U-boat was chased out of the convoy.

At when PQ 18 was about north-west of Bear Island and about to turn into the Barents Sea, the 3rd Destroyer Flotilla returned from refuelling at Svalbard. Twenty of KG 30 appeared and bombed through gaps in the cloud; Sea Hurricanes were sent to intercept but failed to shoot down any of the bombers. At about when the Sea Hurricanes were back on deck and rearming, ships' radars detected several formations of aircraft at range. There was an overcast, the cloud base was at , a moderate sea was running and intermittent showers and sleet obscured the convoy. The bombing succeeded in disrupting the convoy formation as of in two waves, followed by of and seventeen from KG 30 prepared to make a ''Goldene Zange'' attack. One of the Ju 88s shadowing the convoy flew to rendezvous with the torpedo-bombers and guide them to their target.

Standing orders to keep station meant that the anti-aircraft ship , on the left side of the convoy, remained out of range. The escorts closed in, rather than keeping their distance to disrupt the ''Luftwaffe'' formations as they passed overhead; the Sea Hurricanes were still on deck. Boddam-Whetham ordered a 45° emergency turn away from a torpedo attack by sounding a horn and the raising a signal flag, to be repeated by the other ships as they were seen but the ninth and tenth columns (right flank column and the next one to port) maintained course. The torpedo-bombers approached so close to the sea that machine-guns and even the low-angle BL 4.7-inch guns Mk I on some of the destroyers could be brought to bear,

Some of the anti-aircraft fire was poorly aimed and spent rounds from the ships on the left flank hit those on the right, wounding gunners, damaging cargoes and holing lifeboats. The torpedo-bomber formation split to pass the cruiser ''Scylla'' then each bomber dropped two torpedoes and turned towards the stern of the convoy. Some pilots pressed their attacks

''Empire Stevenson'', at the head of the ninth column disappeared in a plume of smoke and was lost with all hands. A torpedo fell straight into a hold of ''Wacosta'', the next ship in the column, exploded and sank the ship, the crew being rescued. ''Oregonian'' at the head of the tenth column was hit by three torpedoes, capsized and only survived, many being badly affected through exposure and swallowing oil. ''Macbeth'', following behind, was hit by two torpedoes and the destroyer came alongside to take off the crew before the ship sank. ''Sukhona'' and ''Afrikander'' were also sunk and the crews rescued by the close escort, leaving ''Mary Luckenbach'' as the only survivor of the two columns. At the head of one of the left flank columns, ''Empire Beaumont'' was hit, set on fire and the crew rescued; ''John Penn'' was torpedoed in the engine room, three men were killed and the ship was sunk by gunfire from the escorts. Some observers reported periscopes inside the convoy and several ships were near-missed by bombs from the above. In fewer than fifteen minutes, eight ships had been sunk for a British claim of five bombers shot down and three probables.

Every bomber had been hit by anti-aircraft fire and four of the I/KG 26 aircraft made emergency landings in the sea; one crew being rescued by (sea rescue service); two of the surviving aircraft were write-offs and several III/KG 26 aircraft in the second wave were shot down. After the attack, several Heinkel He 115 (He 115) torpedo floatplanes, waiting out of range, attacked in two formations but were driven off. One of the floatplanes was attacked by four Sea Hurricanes but escaped after shooting down one of the pursuers. More aircraft were seen mining the water ahead of the convoy, which made a sharp turn to port until Fifteen minutes later, as night fell, twelve He 115s attacked from the south-west but were deterred by the anti-aircraft barrage. Two Heinkels were shot down, one crew being captured and the other being rescued by in the wake of the convoy. (Some late evening losses on 13 September were recorded on the next day.) Colthurst decided that the Sea Hurricanes henceforth would fly standing patrols of 25 minutes duration per fighter, to ensure that some were always available to break up formations, even if they were too slow and ill-armed to inflict many losses. The captain of ''Ulster Queen'' resolved to ignore the standing orders to keep station and steer towards incoming aircraft instead.

The German surface force at Narvik had been alerted when the convoy was first sighted and on 10 September sailed north to Altafjord to begin (Operation Double Hit). The move was sighted by the two British submarines on patrol and made an abortive torpedo attack on ''Admiral Scheer'', erroneously reporting the ship as ''Tirpitz''. Soon after midnight on 10/11 September the Admiralty reported Enigma messages that ''Admiral Hipper'' was due at Altefjord at and in the afternoon that ''Tirpitz'' was still at Narvik. On 13 September, Enigma showed that the ships at Altefjord had come to one hours' notice at which was relayed to the convoy escort commander at The ships were photographed at Altefjord by PRU Spitfires on 14, 15 and 16 September. Enigma showed that ''Tirpitz'' was still in Narvik on 14 September and on 16 September, the Swedish source A2 reported that only ''Admiral Hipper'', ''Admiral Scheer'' and ''Koln'' would operate against PQ 18. had already been called off on 13 September; while the ships were at Altefjord, Hitler, reluctant to risk the loss of any of his capital ships on an offensive operation, had refused to authorise a sortie. The Hampden force in Russia had undertaken an anti-shipping patrol on 14 September but found no targets. (The RAF donated the remaining Hampdens and Spitfires to the Soviet Air Force (, VVS); the crews returned to Britain on the cruiser and two destroyers on 28 October).

14 September

At on 14 September, the oiler was torpedoed by which was being stalked by an escort, the U-boat then dived under the convoy and escaped, cloaked from Asdic by propeller noise. Fires on ''Atheltemplar'' were impossible to extinguish and it was abandoned, to be sunk by the escorts after the survivors were rescued. Swordfish patrols began at dawn and at a U-boat about starboard of the convoy was spotted and marked by a smoke float before a Ju 88 shadowing aircraft saw off the Swordfish. ''U-589'' surfaced again and was seen by an escort heading for the smoke around U-589 dived again, was depth charged several times and destroyed on the eighth attack at When the escort made for the convoy, its captain left a shot-down German bomber crew behind. The Swordfish played cat and mouse with Ju 88s and BV 138s, trying to lure them into range of ships' guns and at a German torpedo-bomber formation of III/KG 26 was reported by a Swordfish to be en route for the convoy at wave top height. The torpedo-bomber formation divided to nullify attempts by the ships to evade their attacks.

''Avenger'' had a standing patrol of Sea Hurricanes aloft and increased speed to emerge from the head of the convoy and run down the port side. ''Ulster Queen'' also left station to meet the attack along with ''Scylla'' and ''Achates''. During these manoeuvres, Boddam-Whetham ordered another 45° emergency turn away. The torpedo-bomber formation divided and one part turned towards ''Avenger''; the barrage made the others release their torpedoes too soon, some of which turned over in the air. No hits were achieved and by eleven Ju 88s had been shot down. KG 30 arrived and dive-bombed from until through breaks in the cloud, opposed by the anti-aircraft fire of the convoy and attacks by six Sea Hurricanes. One Ju 88 was shot down as ''Avenger'' and several other ships were near-missed. At twenty-two He 111s of I/KG 26 and eighteen Ju 88 torpedo-bombers attacked head on, having received reports that ''Avenger'' was in front the convoy. The bombers found ''Scylla'' instead and were attacked from behind by Sea Hurricanes, which dived on the formation as it flew into the anti-aircraft barrage. Several torpedo-bomber pilots saw ''Avenger'' and altered course down the starboard side of the convoy to attack. Three of the Sea Hurricanes which followed the German aircraft into the barrage were shot down by the ships, the pilots being rescued by destroyers. Two He 111s aimed at ''Avenger'' which combed the tracks (steered between them) several bombers did not drop and others did at random.

''Mary Luckenbach'' was torpedoed from by a bomber which strafed the superstructure as it passed overhead, its starboard engine on fire as it crashed into the sea; ''Mary Luckenbach'', the last ship of the ninth and tenth columns, disappeared in a huge explosion. Ships nearby were showered with débris and concussion led the captain of ''Nathaniel Greene'' to order abandon ship, under the impression that it had been torpedoed, until he realised his mistake; two injured gunners were taken off by a destroyer. Five He 111s crashed near the convoy, four more force-landed in the sea and five of the thirteen survivors were seriously damaged. The British claimed 13 torpedo-bombers for a loss of the three Sea Hurricanes. ''Luftwaffe'' records show at least 23 aircraft of I/KG 26, III/KG 26, III/KG 30, I.406 and I.906 were destroyed; I/KG 26 was reduced to eight serviceable aircraft. The crew of one of the shot down bombers was fired on as columns of the convoy passed by. Ju 88s bombers from KG 30 conducted level- and dive-bombing attacks on the escorts until then climbed into the cloud and departed. The Sea Hurricane pilots claimed five bombers and the speed with which the escorts had rescued the three shot down pilots raised their morale. ''Avenger'' had achieved a much better radar-controlled fighter interception than the day before. During the evening, PQ 18 passed Hope Island and some of the 550 survivors were redistributed, 209 being accommodated on ''Scylla'' and 234 on the fleet destroyers due to return with QP 14. One destroyer bound for Iceland took off the unwounded survivors on ''Copeland'', leaving 96 seriously wounded men being treated.

15 September

Dawn on 15 September broke with a calm sea and patchy cloud at ; during the day the wind rose, bringing showers of rain, sleet and snow. Overnight and in the morning, Huff-Duff detected wireless transmissions from U-boats in the vicinity; Swordfish anti-submarine patrols were flown by ''Avenger'' from first light. German reconnaissance aircraft reached the convoy around and near noon, German bombers were detected and Sea Hurricanes scrambled. The raid lasted for about three hours, the bombers attacking through gaps in the cloud cover but fighter attacks and the anti-aircraft fire from the ships prevented accurate bombing. The ''computer'' on ''Scylla'', eavesdropping on 5610kHz, the ''Luftwaffe'' frequency, heard the dismay of the bomber pilots at the size of the convoy. The Sea Hurricanes managed eventually to keep the bombers circling out of range; ''Ulster Queen'' even managed to shoot down a Ju 88 in cloud, aiming with its gun-laying radar. The last bombers departed at but although the weather worsened, U-boat alerts continued all day. Soon after noon, smoke was seen on the horizon, thought to be from surface ships but when an escort steered south-east to check, it turned out to be diesel smoke from two surfaced U-boats. The U-boats crash-dived and a BV 138 nearby was driven off; the ship failed to located the U-boats with Asdic and one of the U-boats made an abortive attack on the ship, which returned to the convoy at The weather deterioration continued into the evening and as the destroyer returned to its station after dropping back to refuel, a depth-charge attack was made on a "suspicious object".

16 September

U-boat contacts were made all night and at on 16 September, ''U-457'' sailed beneath the outer anti-submarine screen and prepared to fire a torpedo salvo at the convoy. ''Impulsive'' gained an Asdic contact, made a depth-charge attack and then lost contact amidst the propeller noises of the convoy. The destroyer passed between the merchant ships as they steamed over the position of the attack, found the suggestive smell of oil and bubbles on the sea, claiming a probable; ''U-457'' had been destroyed. Soon after dawn, the first Catalina from Russia arrived, allowing the Swordfish crews to cease their anti-submarine patrols and at the convoy turned south, running into mist and rising winds. At two escorts attacked a U-boat but it evaded the attack with a ''Pillenwerfer'', a discharge of compressed air which gave the same Asdic echo as a submarine and the hunt was terminated at Wireless contact was made with the homeward QP 14, ready for the changeover and then ''Scylla'' and the FDE departed, along with the ''Avenger'' group, ''Alynbank'' and the two submarine escorts. PQ 18 and the close escort of corvettes, minesweepers and trawlers as a south-easterly gale brought mist and rain. There were constant U-boat alarms and at one point, mines were seen amidst the freighters, leading to the convoy gunners engaging anything seen afloat, to the detriment of seals in the sea, men, superstructure and cargo on other ships.

17–18 September

The Soviet destroyers and arrived before noon on 17 September and made a substantial addition to the anti-aircraft firepower of the close escort; ''Kuibishev'' and ''Uritski'' arriving next morning. At on 18 September, the convoy reached Cape Kanin as the ''Luftwaffe'' made another ''Goldene Zange'' attack. The last twelve operational He 111 torpedo-bombers of KG 26 attacked at wave-top height from astern as the Ju 88s of KG 30 bombed the convoy. ''Ulster Queen'' turned meet the attack broadside; with the first two Russian destroyers, ''Ulster Queen'' fired into the sea to create a splash barrage. A witness on ''Copeland'' reported that the bombers

''Kentucky'' was hit amidships and caught fire. The crew abandoned ship to be rescued, despite the sea state, by nearby escorts. A request was sent by wireless to Archangelsk for tugs to be sent as two escorts waited with ''Kentucky''. As a party tried to board, a Ju 88 hit ''Kentucky'' with two bombs and caused more fires, attracting other bombers to the scene. The escorts tried to finish off the ship with gunfire and then returned to the convoy amidst the ''Goldene Zange''. No Soviet aircraft were available and at ''Empire Morn'' launched Flying Officer Burr in his CAM Hurricane, the last air defence of the convoy. Many convoy gunners fired at the Hurricane until it was out of range and Burr also had to weave through the barrage balloons flown by the merchantmen. Burr attacked Heinkels astern of the convoy and obtained a flamer before running out of ammunition. The torpedo-bombers failed to hit any ships for a loss of three bombers and one seriously damaged.

The ships had been shaken by many near misses by the torpedo-bombers and after the event it was speculated that many of the torpedoes had dud fuzes. In the confusion, the master of ''Empire Tristram'' had thrown overboard the confidential books and begun an abandon ship, before realising his mistake and pressing on. Wild shooting by the convoy gunners wounded one man and hit several aircraft carried on the deck of ''Patrick Henry''. No more torpedo attacks were made on the convoy and soon after, Soviet aircraft appeared and kept away the Ju 88 bombers of KG 30 as the weather deteriorated again. At four British local escorts joined the convoy, which split into two columns as dark fell and the tide in the Dvina Estuary ebbed strongly. Ships crossing the Dvina bar needed navigation beacons but these were not illuminated and some pilot boats failed to appear. PQ 18 had to drop anchor and spend the night riding out a north-westerly gale against a Lee shore. Some ships dragged their anchors or lost them, others started engines and managed to move away from the shore and heave to and two trawlers used their last coal to steam into wind. One ship had to be steered by hand after the steering gear broke down, ''Exford'' lost both anchors and several ships made for the estuary.

20–27 September

By dawn on 20 September, five ships were aground and an attempt by two corvettes to tow off a trawler failed. ''Campfire'', aground, was full of explosives; the captain ordered the crew to abandon and make for Modyugski Island, which was achieved despite the storm and on 21 September, in better weather, the master and several volunteers re-boarded. For the rest of 20 September, the ships waited for the storm to abate and as the winds fell in the afternoon, twelve Ju 88 bombers appeared through the cloud at and attacked, achieving only several near-misses. On 21 September, pilot boats came out and the ships were guided into port. Three warships stayed behind to guard the grounded ships, which were attacked at by two Ju 88s which had more near misses. As the ships moved upstream, Archangelsk was bombed but the raid hit the town, rather than the port. For several days, cargo on the ships stranded on the sandbar was transferred to two heavy lift ships by lighters and a salvage ship, all the ships being re-floated by 27 September; the last ship was re-floated later; discharging the ships took a month. At a reception to celebrate the arrival of PQ 18, the convoy Commodore Boddam-Whetham, was cheered to the rafters.

Aftermath

Analysis

In the official history (1956 962 Stephen Roskill called PQ 18 an Allied success but in 2004, Richard Woodman referred to it as a pyrrhic victory. The convoy operation brought 28 ships safely to their destinations and the Arctic convoy route, which had been suspended since the loss of PQ 17, was open again. The ''Luftwaffe'' torpedo-bomber attacks, while costly, had been highly effective and would have inflicted more losses, had not the British Headache operator not given early warning of some attacks, which enabled Sea Hurricanes to be scrambled in time. The Germans failed to prevent the convoy reaching Russia and their losses, particularly in trained pilots, were severe, reducing the ability of the ''Luftwaffe'' to repeat its anti-convoy operation. Attacks on ''Avenger'' had been defeated and the depth of the escort screen made torpedo attacks on the centre of the convoy extravagantly risky. Coastal Command operations in support of PQ 18 and the returning convoy QP 14, involved 111 aircraft from 14 squadrons, which flew 279 sorties and logged 2,290 flying hours, most being taken up by the fights to and from the convoy. In November, ''Luftflotte'' 5, the German air command in Norway and Finland, was ordered to transfer its Ju 88 and He 111 torpedo-bombers to the Mediterranean against Operation Torch, a decision which the British received through Ultra intercepts. Only the Heinkel 115 floatplanes, suitable for torpedo attacks on stragglers and some Ju 87 dive-bombers remained in Norway, along with a few long-range reconnaissance aircraft to observe for the surface and U-boat forces.

Casualties and losses

The Germans managed to sink thirteen merchant ships for a loss of four U-boats and 44 aircraft including 38 torpedo-bombers and six long range bombers and reconnaissance aircraft. In ''Grand Strategy'' (1972) Michael Howard recorded the loss of 38 aircraft from 309, 126 tanks from 448 and 85 of the 106 lorries carried in the convoy. PQ 19 was assembled at Loch Ewe but not dispatched, amounting to a nett loss to the Allied war effort.
