The catapult's turn "resets" the turn order to the beginning of the battle: that is, after the catapult, just like at the beginning of the battle, the attacker moves first if the speeds are equal.

If there are no towers or catapults, this reset simply occurs at the beginning of the round. (UPD: no, there is no such effect without a catapult).
