I agree take both of the rebels cities if possible. WRE beat me to the one to the SW. Small defensive force to stay and defend my capital, I'm going to kick some Celt and WRE butt. First I ferry a force over near Londinium at the shortest point. Too many pirates to risk otherwise. My goal is to pick up my forces on the other side and land and seige Tara? (Ireland). I've found that the Celtic army at their northern city (?) will board the "one" boat they have to try and relieve the seige. Sink that one boat with you 4 or 5 you brought. Will take one or two attacks, but no more Celtic army. After you take out the Celts go and get Londinium for the money.

I'm currently using that money to build an army to take Eburacum and hopefully lay a ambush on the Romano-British. Various posts have told when and where to expect them as well as how strong they are. I'm hoping the ambush works, the loss of Londinium means no more money and not much of an army left to get any.
