The title says it all, really. Drake's Dilemma - the Green Earth mission where Drake's flotilla is surrounded by Hawke's indirect units, and Kanebi turns up to help.
Win conditions: Destroy the two black cannons to win.
Only I can't get my blooming battleships anywhere near the things without being blown up into smithereens.
I'm not too good at the whole strategy aspect of this game - I muddle along, but my tactic is mainly SMASH! CAPTURE! SMASH! SO this mission is highly infuriating.

Anyone got any strategy tips for this?
Thanks,
