FFF tactical idea-
Couldn't two of the corvettes/gunboats accompanying the Yamoto break formation in opposite directions? That is to say, One... ship stays with the Yamoto to provide torpedo-based attacks, while the other two travel along the coast in opposite directions, so as to be able to harry any lingering coastal defenses and settlements? Since, to my knowledge, the citadel can't split itself apart (or can it? dun dun dun!

just kidding), splitting forces would be an ideal way to cause grief amongst its crew, especially the guinoids. If a land invasion is the ultimate goal here, it's also a great way to get a beachhead earlier. Since the citadel only has, to my knowledge, two heavy guns, getting out of range unharmed would be trivial.
This also gives a group of mass fly- enhanced sharnin swordmages something to do- harry one of the... whatevers.
On the other hand, I have all the tactical knowledge of a deranged wombat, so this might actually be a horrible strategy. I don't know.
