So I was playing a game as the greeks against the AI. First off I gotta say it's always lovely to see the AI smarten up like this. Anyways, my phalanxes were formed along a line. well what do the horsemen do? They run towards my flanks and try to hit the outer phalanx columns from behind.

Now I see them doing this, so what I try to do is rotate my phalanx column to face them, albeit they're doing this slower than the horses are running. As I'm rotating, the spears are up, not down, and they get bruised real badly by the oncoming horses.

Now with that said, I've seen some really crazy fights where horsemen charging into the side of a thickly formed phalanx column fared worse than a phalanx column facing them, but in mid rotation.

I'm tempted to start adopting napoleonic tactics, like if I see cavalry coming, form up into a square.

Does anybody else have experiences like this? Faced with flanking cavalry, rotate or hold?
