Operation Source

Operation Source was a daring British Commando raid conducted in September 1943, targeting the formidable German battleship ''Tirpitz'' and other major Kriegsmarine warships sheltering in Norwegian fjords. Employing X-class midget submarines, the operation aimed to neutralize a critical threat to Arctic convoys supplying the Soviet Union. Although only partially successful, the mission inflicted significant damage on the Tirpitz, rendering it non-operational for months and altering the naval balance in the Arctic Ocean.

Background

Following the failure of Operation Chariot against the Normandie dry dock and the disastrous Battle of the Barents Sea, the Kriegsmarine's surface fleet, led by the battleship Tirpitz, posed a persistent threat to Allied shipping. Based in the protected anchorages of Altafjord and Kåfjord in German-occupied Norway, these capital ships, including the ''Scharnhorst'' and the ''Lützow'', could sortie to attack vital Arctic convoys like PQ 17, which had suffered catastrophic losses. The British Admiralty, under pressure from Winston Churchill and First Sea Lord Dudley Pound, deemed the elimination of the Tirpitz a top priority to secure the Murmansk supply line. Previous attempts, such as Operation Title using human torpedoes and raids by the Royal Air Force's No. 617 Squadron, had proven unsuccessful against the ship's formidable defenses and remote location.

Planning and Preparation

The plan, developed under the auspices of Combined Operations Headquarters led by Lord Louis Mountbatten, centered on the use of six X-craft. These 51-foot midget submarines, commanded by officers like Geoffrey Sladen and Henty-Creer, were designed to penetrate harbor defenses, dive beneath anti-torpedo nets, and deposit side-mounted Amatol explosive charges. The X-craft were towed to the target area by larger T-class and S-class submarines of the Royal Navy, including HMS ''Truculent'' and HMS ''Thrasher''. Intensive training took place at Port Bannatyne on the Isle of Bute and in Loch Striven, simulating the challenging conditions of the Norwegian Sea. Each craft's four-man crew faced a grueling journey, with the passage requiring them to remain submerged for extended periods in extremely cold waters.

Operation

On 11 September 1943, the towed X-craft departed from Loch Cairnbawn in Scotland. During the arduous transit across the North Sea, three craft were lost: X-8 and X-9 broke their tow lines and sank, while X-10 was forced to abort due to mechanical failures. On 22 September, the remaining three—X-5, X-6, and X-7—successfully entered Kåfjord. X-6, commanded by Donald Cameron, and X-7, under Godfrey Place, managed to slip past the boom defence nets guarding the Tirpitz. Both craft placed their charges under the battleship's keel before being detected, scuttled, and their crews captured. The fate of X-5 remains unclear; it was likely sunk by defensive fire from the Tirpitz. The timed charges detonated, lifting the 42,900-ton vessel and causing extensive damage to its engines, steering gear, and hull.

Aftermath

The explosions crippled the Tirpitz, causing significant flooding and structural damage. While the battleship was not sunk, it was rendered unseaworthy and required extensive repairs, sidelining it for over six months. The crews of X-6 and X-7, including Cameron and Place, were initially interrogated by the Gestapo on suspicion of being illegal combatants, but were later treated as prisoners of war. For their extraordinary courage, Cameron and Place were awarded the Victoria Cross. The ''Scharnhorst'', the operation's secondary target, had departed the fjord before the attack, and the ''Lützow'' escaped unscathed. The raid demonstrated the vulnerability of even the most heavily defended capital ships to unconventional, determined attacks.

Impact and Analysis

Operation Source achieved a crucial strategic objective by neutralizing the Tirpitz as an immediate threat to the Arctic convoys, providing a major respite for Allied shipping to the Soviet Union. This allowed for the reinforcement of the Eastern Front ahead of pivotal offensives like the Battle of the Dnieper. The operation validated the concept of midget submarine attacks and influenced subsequent Royal Navy missions, including the later attacks on the Tirpitz by the Royal Air Force using Tallboy bombs. While a tactical triumph of planning and bravery, it also highlighted the high risks and mechanical frailties of the X-craft technology. The damaged Tirpitz was eventually sunk in Operation Catechism in 1944, but Operation Source marked the decisive action that ended its reign as the "Lone Queen of the North."
