I'm currently harassing the largest convoy I've seen yet. It's AT LEAST 50 ships, maybe more! The escorts aren't being very aggressive. I sunk 2 merchants and damaged another before I was out of torpedoes. I slipped away to reload and hide. When sonar didn't show any close contacts, I surfaced to recharge. I should have gone to PD to check first though... there was a destroyer waiting for me with his engines off. He was easy to shake though. I'm taking a break because my head hurts
. Very stressful (in a good way). It's hard to target when there are so many ships around.
I'm going to try to stalk the convoy, then take another run at it when it's dark again. Almost out of torpedoes.
