Heck of a patrol already! I'd say go ahead and sink 'em. I'd imagine a real life Kaleun would puff thoughtfully on his pipe and say something along the lines of "Eat now, you don't know when you'll get the chance to again."

EDIT: The U-Boat Commander's Handbook backs us up on this one: "Never delude yourself by assuming that it is right not to attack on the instant, or not to hold on to the enemy with the utmost determination, because there may be reason to hope and believe that there will be a better target subsequently found elsewhere. What you have got, you have got."
