Yeah, you're OFF all right!!
The question was raised about the actions that earned Lt Benzie his DFC, and VinRouge linked an article to explain what those actions were.
That article made no specific mention of his actions and only listed his MID!
Therefore, since I lack your god-like knowledge of everything in the universe, I thought a mistake had been made with which award Lt Benzie had actually been honored.
I now know, thanks to PTC REMF's helpful (something you apparently know nothing of how to do) response, that he was later awarded the DFC... the details of his actions which earned it remain unexplained in this forum.
