I just fought a particularly nasty battle against the Timurids---it was their last citadel, though, and I was tired of fighting Elephant Artillery so it needed to be done. The AI knew what was coming it seemed, and huddled six units of elephants all in the square. So it was a nightmare piercing through to them, and when I finally got there, every time one would rampage it would go right through my troops, causing massive casualties.

That wouldn't do, so I hauled my culverin up to the topmost wall and blew two holes in it so I could assault from multiple directions; when the elephants rampaged, it would only wipe out a portion of the army. It was a very near thing---many units only had 2 or 3 men left in them---hardy souls indeed!!
