I was playing a game with Polish and controlled all Europe east of Venice.
When the mongols appeared it was a easy campaing to ban them from Europe. It took four moves for me.
Ofcourse it is easy when you know the date http://www.totalwar.org/forum/non-cg...cons/smile.gif
I moved enough troops to meet them. Lined up in Kiev to Muscovy and a few defence battles and then attack and kill the Khan. Peace of cake. But it can bee tricky with others when you can't go up and meet them with power.
