Hello,

RORQUAL sighted the lights of a fishing vessel from the direction from which the torpedoes were fired but it was too distant to have sighted the submarine. There was the possibility this was an armed trawler or a Q-ship but this is improbable as the Germans would not run Q-ships in areas used by U-boats [I think that they did use some off the Spanish coast]. I can confirm that there were no Italian submarines in this area at this time. It is most likely that porpoises were mistaken for torpedoes.
