I'm into March '43, and just had an INCREDIBLE run in with a large convoy in AM71. Ships everywhere including the first T3's I've seen. Don't you know I've got to take out escorts! Saving the game (thinking I'll be dead soon) I throw caution to the wind and go crazy. 7 escorts go down with one fish each. It almost seemed they only wanted to go to the sinking ships, rather than come after me. Enough of them remained to nearly sink me; I've got three dead, many wounded, but I am underway on the surface and headed for France.
