Background
Strategic situation
Before the outbreak of World War II the Kriegsmarine (German Navy) developed plans to attack Allied merchant shipping in the event of war. The navy's commander, Grand Admiral Erich Raeder, believed that battleships and cruisers were a key part of this strategy. As a result, the Scharnhorst and Bismarck-class battleships that were constructed in the late 1930s and early 1940s were designed to be capable of making long-range anti-shipping raids into the Atlantic Ocean.[1] Tirpitz was the second of the two Bismarck-class vessels and was launched in April 1939 and commissioned on 25 February 1941.[2]
The Kriegsmarine made two battleship raids against Allied

The battleship was relatively safe from air and naval attack at Fættenfjord, as it was distant from British bases and well protected. The defences against air attack included
The Royal Air Force's (RAF) Bomber Command was directed to attack Tirpitz at Fættenfjord using heavy bombers.[5] The first such raid was made on the night of 28/29 January 1942 by 16 heavy bombers; no damage was inflicted.[18] On 6 March Tirpitz and three escorting destroyers departed Fættenfjord to attack two Allied convoys that were passing through the Norwegian Sea. These convoys were escorted by elements of the British Home Fleet, and planes operating from the aircraft carrier HMS Victorious made an unsuccessful attack on Tirpitz on 9 March. Following this operation Hitler directed that Tirpitz was to not attempt further attacks against convoys unless it was first confirmed that no aircraft carriers were nearby.[19]
RAF heavy bombers repeatedly attacked Tirpitz at Fættenfjord during March and April 1942. Raids were conducted on the nights of 30/31 March, 27/28 April and 28/29 April. No damage was caused to the battleship, and 12 British aircraft were destroyed.

Development of the Chariot

The destruction of Convoy PQ 17 led to an increased determination among the Allied leadership to neutralise Tirpitz. As the RAF raids had failed, the Admiralty came to believe that attacks against the battleship at its anchorage using small submarines should be attempted.[27] It was not possible to use full-sized submarines as the shallow depth of Fættenfjord meant that they would likely be detected before an attack could be made.[28]
At this time the Royal Navy had two types of small submarines under development, the Chariot manned torpedo and the X-class midget submarines.[27] Development of both types had begun in 1940. Manned torpedoes were used by the Regia Marina (Italian Navy) to damage two British battleships, while at anchor at their base in Alexandria, Egypt, on 19 December 1941. Following this attack Churchill asked the Chiefs of Staff Committee to explain "what is being done to emulate the exploits of the Italians in Alexandria Harbour".[29] By the start of February 1942 the commander of the Royal Navy's submarine service, Admiral Max Horton, was developing plans to use manned torpedoes and midget submarines.[30]
Trials of the first Chariot manned torpedo began in April 1942.[31] Volunteers to operate Chariots and midget submarines were also sought in early 1942. The appeal issued by Horton noted that the volunteers would undertake "hazardous service" but, to preserve secrecy, did not specify what this would involve. By April 1942 30 men had been recruited.[30]
The Chariot had a crew of two, a commander and a number two. It was 22 feet (6.7 m) long and weighed 3,500 pounds (1,600 kg).[32] Its single propeller was powered by an electric battery which gave a maximum range of 18 miles (29 km) when travelling at 3 knots (5.6 km/h; 3.5 mph).[33] The craft were armed with a single detachable warhead containing 600 pounds (270 kg) of explosives.[32] It was intended that Chariots would be transported by a ship to near their target. The crew would then penetrate the enemy defences, which were expected to include metal anti-submarine and anti-torpedo nets. Once done, the number two would attach the warhead to the target ship's hull using magnets. The warheads had a time-delay fuse to allow the Chariot crews to escape before it detonated. As the Chariot did not have enough range to return to its mother ship, it was intended their crews would head for the shore after completing their attack and escape overland to neutral Sweden.[34]
Extensive trials and other developmental work were conducted during 1942 to perfect the Chariot's design and develop tactics for using them in combat.[35] The crews were also put through gruelling training to prepare them to make attacks and escape overland. Despite the difficulty of the training and the risky nature of the Chariots' intended missions, few of the volunteers withdrew.[34]
Preparations
Plans
Work on a plan to attack Tirpitz at Fættenfjord using Chariots began in mid-June 1942. It was developed by Captain
Consideration was given to inserting the Chariots into the target area by air. One proposal involved the craft and their crews being parachuted from Handley Page Halifax bombers, but this was ruled out due to the difficulty of the crewmen being able to locate their Chariot after being dropped into the sea at night. Another proposal involved using Short Sunderland flying boats to land the craft and five aircraft were modified for this purpose. The Sunderland proposal was later abandoned as it was judged unlikely that these large aircraft would be able to reach Fættenfjord without being detected.[38] The planners also considered using a British warship to transport the Chariots and their crews, but this was rejected in favour of using a Norwegian freighter or fishing boat.[39]
It was decided to transport the Chariots and their crews by sea from the UK to the island of Frøya to the west of Trondheimsfjorden. The Chariots would then be attached below the waterline of a boat provided by members of the Norwegian resistance, which was to bluff its way through the German defences of Trondheimsfjorden and sail to the island of Tautra to the north of Fættenfjord. The crews would board the Chariots near Tautra and attack Tirpitz.[38] Pound approved this plan on 26 June.[38][40] The attack was designated Operation Title and scheduled to take place in October 1942.[41] Horton and Wilson were given joint overall responsibility for the operation.[40]
Selection of participants

Following Pound's approval of the plan, contact was made with the resistance in Trondheim through a Norwegian diplomat stationed in Sweden. The resistance agent Arne Christiansen travelled to Trondheim to seek assistance from a resistance network there. The network's members provided information about German security measures in the area and how they could be evaded. This included information on the documents that ships travelling in the waters around Trondheimsfjorden were required to carry by the German occupation authorities, with the resistance agents offering to provide copies. Christiansen also attempted to recruit a fishing boat captain at Frøya who was willing to transport the Chariots.[42][43]
In the meantime, the Chariot force continued training at
Christiansen was unable to persuade any fishermen at Frøya to provide a boat. One man who was approached declined to cooperate due to the likelihood of Germans retaliating against his family if his role became known. Wilson decided to use ships and personnel from the Shetland Bus force instead.[26] In August Mitchell met with Larsen and asked if he would be willing to take part. During this discussion Mitchell explained the plan and noted that the attack would be very dangerous. Larsen immediately agreed.[46] He was subsequently heavily involved in finalising the plans for Operation Title.[39]
The day after agreeing to take part, Larsen met with Wilson in London and was directed to use one of the Shetland Bus force's boats and recruit a crew of three. He chose three of his friends for the crew.[47] They were the engineer Palmer Bjørnøy, deckhand Johannes Kalve and radio operator Roald Strand. Larsen was unable to disclose the nature of the operation, but warned the men that it would likely cost their lives.[48][39] To carry the attack force Larsen selected a boat named Arthur which he had stolen during an October 1941 minelaying attack in Norway.[47] The boat and its engine were both elderly, and few checks were made to confirm whether it could reach Trondheimsfjorden.[49]
Two teams of Chariot operators were also selected. One comprised Sub-Lieutenant William Brewster and Able Seaman A. Brown. The other was made up of Sergeant Don Craig (a soldier in the British Army) and Able Seaman Bob Evans. The two other operators who travelled on board Arthur, Able Seamen Billy Tebb and Malcolm Causer, were to help the Chariot crews to don their bulky Sladen Suits and serve as spare crewmen if needed.[50][51][a] Brewster commanded the Chariot unit, with Brown as his deputy.[40]
Arthur needed to be modified for the operation, including to carry two Chariots. The craft were to be transported on her deck for the first part of the operation and be towed underwater for the last 100 miles (160 km) to Fættenfjord. A derrick was added to the boat to lift the Chariots into the water.[54] Larsen personally installed two large eye bolts to the hull of Arthur to which the noses of the Chariots were to be attached via steel hawsers while they were towed. A secret compartment was also added to hide the four Chariot crewmen and two support operators from any German personnel who inspected the boat in Norwegian waters. Arthur was disguised as a similar boat known to be operating in Norway.[55]
Final planning
The final plan for the attack specified that Larsen was to

During the first week of October Arthur and the two Chariot teams made a final practice attack against the battleship HMS Nelson. This was successful, with the Chariot teams cutting through the nets surrounding the battleship, attaching their charges and escaping undetected.[50] The attack force then proceeded to Lunna House in the Shetland Islands where the men awaited orders to begin the operation.[59]
A set of falsified papers for Arthur and its crew was prepared in October. These documents were extensive, and included
Tirpitz returned to Fættenfjord on 23 October and was sighted there by a RAF photo reconnaissance aircraft the next day. On 25 October Horton ordered Operation Title to be initiated, with the attack scheduled for the 31st of the month.[59]
Attack
Voyage to Trondheimsfjorden
Arthur sailed at 9 am the morning of 26 October. The weather was bad throughout the voyage to Norway, causing several of the seamen to suffer from
Edøya was reached during the morning of 29 October and Arthur's crew anchored there.[59][b] The plan for the operation called for the Chariots to be fitted with their warheads, unloaded from Arthur and secured to the boat while at Edøya. Attempts to do this during the morning were frustrated by several German aircraft which flew low to inspect the ship. All work had to be stopped each time and the British personnel hid below deck. While the warheads were fitted to the Chariots after the German aircraft stopped patrolling, rough seas caused Arthur to drag her anchor. This made unloading the Chariots impossible and the crew decided to find a better anchorage. This took the rest of the day.[65]
Work to unload the Chariots resumed at 5 am on 30 October.
Before reaching Trondheimsfjorden Larsen intended to visit the small town of Hestvik to meet with the storekeeper Nils Strøm, who was to provide information on German activities in the region. During the voyage to the town Arthur's engine began to make loud knocking noises. Bjørnøy inspected the engine and found that a piston was damaged and needed to be urgently repaired. When Arthur reached Hestvik at 11 pm that night Larsen directed Bjørnøy to repair the engine while he met with Strøm.[69] The Norwegian shopkeeper provided information on German security procedures. Bjørnøy was unable to repair the engine as the piston had cracked, meaning that it needed to be replaced or repaired with more sophisticated tools than were available on the boat. Strøm arranged for a trustworthy local blacksmith to be woken up, and he agreed to let Bjørnøy use his forge to repair the piston. After spending two hours working on the piston, Bjørnøy reassembled the engine and judged that it would last for long enough to get the boat to Fættenfjord.[70]
Trondheimsfjorden
Arthur departed Hestvik at 9 am on 31 October.[70] The boat sailed at half its usual speed to reduce the strain on the engine.[71] As the waters between the town and Trondheimsfjorden were regularly patrolled by German security boats and it was expected that Arthur would be stopped for questioning, the British personnel hid below decks with a machine gun at the ready. The Norwegians were armed with pistols. A German patrol boat was sighted at 10 am but did not stop Arthur.[70] Other German boats were later encountered and also let Arthur pass.[71]
