They will join the battle but it won't be in the fort, it will be on the open field. And since your opponent controls the territory outside of your castle he is free to move away from the siege and avoid your siege break + attack combo, or even attack into the army that you are moving onto the castle. Unless, that is, the army that you are moving onto the castle has more Power Points than his army, which goes into esoteric calculations that you'd have to read the manual to really know, like many things in this game
