Oh, and for the love of Bob, don't ever, ever stay at periscope depth to watch the carnage after you let slip the eels of war, no matter how satisfying the sight is.

Make up your firing solution, loose your eels, then dive like crazy if the convoy is escorted and run away from where you were when you let go. Flank until the escorts get close. This is your only opportunity to use that. Then wait 'em out. The ones who didn't sink you can pick off when the convoy and escorts move on.

As to "the ones who got away?" Forget about them. Your mission is to get away after the action to fight another day.

Keep in mind what sober said: Think like a skipper.

Your boat is an offensive weapon. On the defense, it's worthless. Don't even think about slugging it out with escorts, because you'll lose every time. Your only defense is your invisibility, and your only hope for survival is to not be where your enemy thinks you are when they start dropping depth charges. Because if they have a fix on you, you're in trouble.

Better to make a hundred "less than perfect attack runs" than to die in your first because you just can't resist the temptation to try something that your boat was never designed for.

Hit and run, even when your hit misses. Chalk it up to experience and know that you're still around to hit a second time.
