In my current campaign as the Scots. I have set up a defensive line at the fords and bridges south of Vilnius in Russia to hold off the Mongols. I use forts on the far side of the river to slow up the mongols if needed. With a stack on the river crossing behind the fort. The Mongols seem to prefer to attack the stacks at the river crossings instead of the lightly defended forts. Not sure why? I am glad to oblige them with a defensive battle at the river crossings though. They charge across the river into our pikes, the mongols route, and we chase down the stragglers. Basically I am playing a defensive game of attrition I know the Scots will win. The Scots have an empire if 30 provinces, the mongols have 1 province, and only 8 full stacks left (I have already decimated 4 stacks). The Scots campaign strategy is kind of like the Union army of the Potomac under Grant in the American Civil war. Big differnce her is that I am inflicting 3 or 4 times the casualties on the Mongols. It would be much higher , but many of the mongol mounted troops are faster than most of my army. The Scots Border horse are my only comparable units in speed of movement. So many routers escape I have managed this strategy with 3 full sized stacks so far. Although the the Scots are almost ready to field a fourth stack to face the mongols. The key to an attrition strategy against the mongols is having a good enough economy to afford 4 - 6 full stacks just to face the mongols 12 full stacks. In thi campaign I am also carrying on campaign in france, Spain, and N. Africa with full stacks. As I have said in other posts. It is all about the money. Economic might is easily converted into military might.
