Post your ships' levels, equipment and order.

If you're having difficulty, one of the first things to try is leveling them up (which can be done on the first node of 2-4-A).

If you have a sub, you can attempt to "sub cheese" it, which means you send just a sub to the map and hope it can get to the boss battle and get a B. This works because only certain ships can target subs, mostly DD/CL with a few exceptions.
