To sink the Royal Navy, all you need is one SoL and 3 Great Generals. First, move all other units out of the tile, and attach a GG to a SOL. It will get 20 xp Then, move one unit into the same tile and attach a GG to that unit. The SoL will get 10xp Move that unit out and move a new one in, and attach a GG. The SoL will get 10xp. Your SoL now has 40xp, which is enough to get veteran 1-6 promotions, a total of +75% strength. If you have any rebel sentiment worth speaking of, you should have virtually guaranteed victory against the King's Man of Wars. You can kill one every three turns, counting time to heal.
