The Pope
Sergeant Knight

I've been knocked out in fights a few times and had my entire army vanish, despite the fact that a fair few of them hadn't yet entered the battle. Most of the time I repeatedly get the "Order your troops to attack while you stay back" option until my troops win or lose. Each time, I had a small number of wounded troops (1 or 2 out of about 20), but I only got about 5 with me throughout the battle.
