I was reading earlier about the confrontation between the Hipper and the HMS Glowworm. The commander of the Hipper was so impressed by the courage of the crew of the tiny Glowworm that he sent a letter to the Admiralty via the Red Cross recommending his opponent for a Victoria Cross - Which he got posthumously.
I believe something similar happened after the raid on St Nazaire - A story no one would believe if they made a movie about it.
Does anyone have the text of either letter? I've had no luck finding them.
