Pictures?
that would go something like this:
Brag explaining to the gestapo:
"look this is the picture we took while boarding that large cargo because we suspected it had booze on board, but it turned out to be bananas so we scuttled it"
"oh and here's one of Bernard's thumb again, but I assure you I ordered him to take a picture of that Battleship sinking, do I get another medal now?"
"and this one we sunk because we caught one of their sailors taking a leak over the side which you can see in the next picture.."
und so weiter...:p
