Trying to penetrate Rabaul harbor in an S-boat, in February '42. The time is 1900 --- quite dark. Enemy destroyer (type as yet undetermined) patrolling 3000-4000 yards outside the harbor in deep water.
The harbor itself, of course, is shallow. I don't know what, if anything, is inside.
My options:
(1) Confront the destroyer in deep water outside the harbor, and then penetrate.
(2) Sneak around the destroyer, get into the harbor, and deal with him on the way out.
My inclination is to go with option (1), as the risk is relatively low. If I fight the destroyer first, should I:
(a) ambush him with a spread?
(b) ping him to provoke a charge, and shoot down-the-throat?
Haven't had much luck ambushing destroyers.
Curious to know how everyone deals with this problem.
