I'm looking a ta similar situation, only a couple of provinces to go till I have all of Gaul. I'm in an alliance with Britain and Spain.
My plan is to build up a few good size armies and march some into Spain and put them near the cities (placing my forces like chess) I'll also set up my naviy ships in a position to blockade quickly.
I'll alos garrison my border with the British provinces with strong armies.
ONce I have everything in position I plan in one turn to blockade all Spanish ports, and beseige as many Spanich cities as possible whilst keeping an eye on the Britons.
Will this wok, I dunno, could be fun to try though.
If I pull that off I'll then take out Britons avoid the Germans and head towards the Macedonions.
