Quickly:
1. Pretend a grizzled Lochagos has yelled out, or blown a whistle, or whatever they did to command the unit.
2. Take them out of phalanx formation.
3. Reform their position manually, without making them retreat much -- just redraw the square as close to where they already are as possible. Better units can withstand a backward "retreat" movement but if they are levy and already under stress this may make them rout. Either way it's better to reform the position exactly where they are versus moving backward if you can help it.
4. Re-engage phalanx formation.
A friendly unit engaging as many of the enemy as possible just before you begin this is ideal. Otherwise you may have a lot of casualties/rout depending on unit quality and what their morale is at the time. If they're already flagging, I wouldn't bother with this, they'll probably rout immediately.
Either way, drink wine. It is the nectar of gods and men.
