I recall reading that the HMS Campbelton was very well equipped with hard to obtain civilian luxuries, as well as high explosives, so that once the British Commandoes were driven off or captured, the German Officers of St Nazaire and their mistresses soon flocked aboard the damaged destroyer to inspect it and take advantage of some of the luxury items aboard. When the Campbelton blew up, the explosion killed hundreds of Germans, both aboard the ship and close by on the surrounding docks. Damnably ingenius of the British to pull a trick like that on the Germans.
