Operation Source - September 1943
In September 1943 six in X-Craft were towed by six Submarines to attack German Capital Ships in the Kaa Fjord in Norway. In all (apart from the Towing Submarine Crew) forty-two X- Craft personnel took part in Operation Source, eighteen Passage Crew Members and twenty-four Operational Crew Members.
| 08-02-1943 | Completed |
| 03-10-1943 | On 12th September X10 departed Loch Cairnbawn under tow from HMS Sceptre to take part in the attack on the Scharnhorst. At the appointed time the operational crew took over from the passage crew and proceeded to where the Scharnhorst lay at anchor. A fire in the periscope motor prevented the X-craft from pressing home the attack and she had to withdraw and was taken undertow by HMS Stubborn on 28th September. On 3rd October the tow parted and only with great difficulty was the submarine brought back under control. That evening Stubborn received a gale warning and the order to scuttle X10 at the captains discretion. This was duly done and Stubborn returned to Lerwick. |
