Operation EF (1941)

Operation EF (1941), also Raid on Kirkenes and Petsamo took place on 30 July 1941, during the Second World War. After the beginning of Operation Barbarossa, the German invasion of the Soviet Union on 22 June 1941, Fleet Air Arm aircraft flew from the aircraft carriers HMS Victorious (R38) and HMS Furious (47) to attack merchant vessels in the northern Norwegian port of Kirkenes and the north Finnish port of Petsamo.

The War Cabinet and Admiralty pressed Admiral John "Jack" Tovey, commander of the Home Fleet, to attack despite his reservations that the prospects for success were not commensurate with the risks. The operation was intended to be a surprise but in the far north, the midnight sun at that time of year made it unlikely that the raiding force would go undiscovered.

A German aircraft passed Force P and the carrier aircraft flew over a ship on their flights to Kirkenes and Petsamo, depriving the attackers of surprise. The Kirkenes force was intercepted by several German fighters, as the aircraft attacked the few ships to be seen in the harbour, sinking one ship and setting another on fire. Eleven Fairey Albacores and two Fairey Fulmar fighters were shot down, for a loss of two Luftwaffe aircraft.

The force attacking Petsamo faced less opposition, losing a Fulmar to engine failure on the flight to the target and a Fulmar and an Albacore shot down during the attack. Minor damage was caused to jetties, a shipyard and oil storage tanks. The enterprise has been called an "unqualified disaster"; twelve Albacores and four Fulmars had been lost with nine men killed and 27 taken prisoner for no appreciable result; two Fulmar crew reached Russian territory after two days at sea in a dinghy.

Continuation War
In early September 1940, Germany and Finland promulgated a transit agreement for members of the Luftwaffe to travel through Finland to Kirkenes in north Norway, despite a similar agreement being in force with Sweden from April 1940. In Directive 21, the instructions from Hitler for Operation Barbarossa, Murmansk was to be isolated by a military operation to cut the 1350 km Murmansk–Leningrad railway, to prevent the Red Army from moving forces from the interior, to attack the iron ore mines in northern Sweden and the nickel mines around Pechenga, only 100 km from Murmansk; the Luftwaffe base at Kirkenes was only another 50 km further on. Luftwaffe reconnaissance revealed a considerable garrison at Murmansk and excellent rail marshalling yards and port facilities.

On 3 February 1941, the German Army of Norway received its operation order for the coming campaign, making the defence of northern Norway its priority. Gebirgskorps Norwegen was to operate in Finland in defence of Pechenga in Operation Rentier until Finland declared war. The Finns were to cover the deployment of German troops in central Finland and to recapture Hanko, then operate to the south-west wither side of Lake Ladoga when Army Group North had reached the Dvina river, meeting the German forces at Tikhvin. The German invasion of the Soviet Union began on 22 June 1941 and the German offensive against the Murmansk railway Operation Platinum Fox began (29 June – 21 September), part of the larger Operation Silver Fox (29 June – 17 November)

Naval operations
The German submarines U-81 and U-652 began operations off the Kola Inlet in July and five destroyers transferred to Kirkenes to join the training ship Bremse and other vessels. Before the German invasion of the Soviet Union, the Home Fleet was mainly concerned with the exits of the North Sea from Norway to Greenland After 22 June 1941, the emphasis of the Home Fleet began to shift northwards, from Norway to the Arctic. The Soviets pressed the British to attack Axis sea traffic from Petsamo and Kirkenes. The governments in London and Washington were aware of the importance of the importance of Murmansk as an entrepôt for Allies war material. The Admiralty pressed Admiral John Tovey to use the aircraft carriers HMS Furious (47) and HMS Victorious (R38) in operations against Axis shipping off northern Norway and Finland. Tovey stressed the risk in operating carriers so close to Luftwaffe airfields in conditions of the midnight sun which in northern Norway lasts from about 14 May to 29 July. The Admiralty over-ruled Tovey and ordered him to conduct Operation Crucifixion with "Force P".

Force P
Furious embarked Fairey Fulmar fighters of 800 Naval Air Squadron (NAS) and four Sea Hurricane of 800A Flight; nine Swordfish of 812 NAS and nine Fairey Albacores of 817 NAS. Victorious had the Albacores of 827 and 828 NAS and the Fulmars of 809 NAS. Rear-Admiral Frederic Wake-Walker in HMS Devonshire (39) sailed from Scapa Flow on 23 July with Force P, the carriers, HMS Suffolk (55) and the destroyers HMS Escapade (H17), HMS Active (H14), HMS Anthony (H40), HMS Achates (H12), HMS Antelope (H36) and HMS Intrepid (D10). The force reached Seyðisfjörður (Seidis Fjord) in Iceland on 25 July, refuelled and sailed the following day for Norway. Achates struck a British mine off Iceland on 25 July and lost its bow; having to be towed home by Anthony; the destroyers being replaced by HMS Inglefield (D02) and HMS Icarus (D03). Little opposition from the Luftwaffe was expected, despite the intensity of German ground operations in the direction of Murmansk and the Fulmars were expected to provide adequate air cover during the attack.

The aircrew on Victorious were briefed to attack Kirkenes and those on Furious to raid Petsamo. Should the harbours be empty, the force from Victorious would attack an iron ore plant and those from Furious some oil storage tanks. During the night of 26/27 July Force P made course for its rendezvous, about 80 nmi north-east of Kirkenes and arrived three days later, dangerously within range of land-based aircraft and dependent on their fighter cover and anti-aircraft guns and the cloudy weather gave way to clear skies, increasing the risk of discovery. Just before the aircraft began to take off, a He 111 aircraft was seen, foiling the attempt at surprise. The three Albacore and one Swordfish squadrons took off first and the Fulmars followed after twenty minutes, with the Sea Hurricanes guarding the ships.

Kirkenes
Victorious sent two sub-flights, consisting of 12 Albacores from 827 NAS, eight from 828 NAS and nine Fulmars from 809 NAS. The crews of 827 NAS were to attack ships around the Tower of Kirkenes and Langfjord as the eight from 828 NAS concentrated on Holmengraafjord and the anchorage east of Renoy Island. The aircraft flew towards the sun at low altitude to evade radar but flew over a German hospital ship, losing any remaining hope of surprise, then climbed to 3000 ft over the coastal mountains, being engaged by anti-aircraft fire as they did. The crews fired the Luftwaffe colours-of-the-day as a ruse but this failed and the ground fire increased and then suddenly stopped. Thirteen Messerschmitt Bf 109 and Bf 110 fighters appeared, escorting nine Ju 87 (Stuka) dive-bombers from a raid. The shipping in the harbour turned out to be a Kriegsmarine training ship and two medium-sized freighters, which were attacked, bomb hits on the two merchantmen being claimed after the raid. The Fulmar escorts tried to divert the German fighters from the Albacores and shot down a Bf 110 for the loss of two Fulmars. The Albacores released their torpedoes quickly to get away from anti-aircraft fire, sinking one 2000 LT vessel, setting another on fire and causing minor damage ashore. The Albacores tried to escape the German fighters, having the advantage of manoeuvrability but eleven were picked off. An 827 Squadron pilot claimed a Ju 87 which flew in front of his Albacore which was borne out later by German records. Incomplete German loss records confirm the loss of at least one Bf 110 to a Fulmar and one Ju 87 to an Albacore.

Petsamo
Furious sent nine Swordfish of 812 NAS and nine Albacores of 817 NAS to raid Petsamo. A Fulmar was lost due to engine failure prior to the attack and the remainder found a harbour almost deserted, except for anti-aircraft guns. The aircraft dropped their torpedoes against a small ship and the jetties but these were wooden and easy to replace. The 800 NAS Fulmar bombers attacked a shipyard and the oil storage tanks but had little effect. The attackers were intercepted by Bf 109 fighters; an Albacore and a Fulmar were shot down.

Analysis
By the early evening, the surviving aircraft had landed on their carriers and Force P began the voyage back to Scapa Flow. On 31 July a Dornier Do 18 began to shadow the force until two of the Sea Hurricanes shot it down. In 2005, Ron Mackay called the raid an "unqualified disaster"; twelve Albacores and four Fulmars had been lost with nine men killed, 27 taken prisoner and the two Fulmar crew who had engine failure had managed to reach Russian-held territory in their dinghy after two days at sea. The vulnerability of the Albacore and Fulmar aircraft against modern fighters had been demonstrated but the Swordfish of 812 NAS had escaped loss, perhaps because the raid on Petsamo had encountered less opposition than that on Kirkenes. Mackay wrote that it would have been better to send the Sea Hurricanes to cover the raid, despite hindsight suggesting that four Sea Hurricanes were hardly adequate to defend the ships. The commander of Furious called the raid

"...a bitter blow to the attacking force, who were tee-ed up for really big things, to find they had come over two thousand miles to attack a place without a single real military objective."

- Captain A. G. Talbot

Casualties
In 2005, Ron Mackay wrote that twelve Albacores and four Fulmars had been lost with nine men killed, 27 taken prisoner and two rescued by the Russians after two days at sea. In 2012, Jones wrote that 16 aircraft were lost in the raids. In 2014, Chorlton rote that Victorious lost 13 Albacores and their crews in the raid.

Subsequent operations
The Albacore squadrons were transferred from Victorious during August and replaced by the Albacores of 817 and 832 NAS. Victorious became part of Force M operating towards Bear Island and the approaches to the White Sea during Operation Dervish. On 3 September, an attack on ships sailing from Tromso to Kirkenes began but when cloud cover dissipated, the formation leaders aborted the attack according to their instructions because to the risk of interception by the Luftwaffe fighters at Banak. Force M remained off the Norwegian coast and on 12 September an attack was made on ships and shore installations at Bodo, one ship being sunk and an aluminium factory at Glomfjord being damaged. The lack of fighter opposition led to a second raid being planned but this was cancelled when the force was spotted by an He 111. Victorious was carrying two Grumman Martlet fighters borrowed from HMS Argus (I49) which caught up with the German bomber and shot it down. Two Blohm & Voss BV 138 flying boats began to shadow the force and the FAA Fulmars found it impossible to penetrate their armour with .303 Browning machine-gun fire. A raid on 9 October was hampered by heavy seas, five of the 13 Albacores on deck being damaged; three Albacores managed to find and attack a freighter. During the afternoon, eight composite crews from 817 and 832 NAS attacked two merchantmen which were escorted by flak ships and achieved several bomb hits, once ship crew taking to their lifeboats.
