On a related subject, if the kings unit loses men during a battle, it always gets replenished. I had one battle in which my King's unit was down to himself. After the battle, he was back up to full (I'm not sure if the game first takes men from other units before creating replenishing any loses, or if the King simply automatically replenishes without any loses to other units. There is no reason to retrain the king, and as one person mentioned, the King seems to automatically get any upgrades.
Well the king gets replenished from other units of the same type, if they were in the battle with your king (e.g. the prince). I've seen this happen to other units after battle. Units automatically get transferred to the best general of that type if you haven't switched it off. And what was meant by retooling we agreed that the princes get the upgrades, not the kings.
