Ireland (me) declare Holy War for Brittany on Norway! (6.000 vs 4.000 men)
Norway calls in Russia for help! (8.000 men come)
Ireland calls in Francia for help! Francia pussy out!
Ireland savescum!
Ireland declare Holy War for Brittany on Norway! (second take)
Ireland calls in Francia for help! (16.000 men)
Norway calls in England for help! (24.000 men)
What follow is a six-years long clusterfuck where Brittany is taken by the Ireland-Francia alliance, then retaken by the Norses, then taken again. Including a peasant revolt in Rennes beating up some englishmen, Russia coming along with Jutland (norse denmark) and being beaten up, Ireland hiring three mercenary companies after losing half the combined army, Francia losing all their troops save for 6.000 men following the 500 irishmen in Britanny, Ireland being taken back with mercenaries, and a proper final battle with a 9000 strong english army menacing the 6.000 or so Irish/Francia army, being reinforced at the last minute with 2.000 mercenaries coming in boat from Ireland and the 7.000 Italian army coming out of nowhere to help their fellow christian.
The best thing in this is that England is now 20.000 men short of what they used to have. I'm rebuilding and then I'm going to holy war the crap out of them. >
