Among the boats carrying out the attack is X-10, crewed by Ken Hudspeth (📸 IWM A 19626), Bruce Enzer, Leslie Tilley and Geoff Harding. Their attack has to be called off while navigating up the fjords as their sub develops multiple faults.

They 'sit tight' on the bottom to avoid detection and possibly compromising the operation, and later successfully rendezvous with their 'towing' submarine to head back to the UK. (📸 U. Gernhoefer/Adobe Stock)
