The current battle system is pretty simple (but also strangely complex with its unpredictable unit behaviors). Two forces take opposite sides, and go at each other head on.
What records exist out there about Medieval battles, both accounts of the battles, and preferably, reliable sources about the formations and tactics used? I am told that the Medieval Europeans really did fight like BM portrays, but I'd like for something from the time, like a treatise on battle by some competent vassal or someone related to the military scene.
