I do remember a battle I had in Med 2 where the AI, inexplicably went into a shiltrom formation and just stayed like that. I was not cavalry heavy, maybe 4 units max in a full stack, but I had some arty with me.

Those formations made big fat targets for my cannon. I imagine the square formation would be the same. I havent had an occation to put line companys in square formation yet but I have seen it practiced in reenactments so I know what it looks like.



Learn to use your cannons right people! This is the age when artillery earned the name, The King of Battle. Artillery is the new cavalry.
