If you're under siege and summon, do the summoned creatures appear inside the castle, or in the province where they initiate a battle with the besiegers?

Can you attempt a limited breakout? Set part of your defending army to breakout, let them fight a battle, but the other half stays in the fortress?

On the same lines, if you attack a province where you are under siege, does the garrison automatically try to break out and join the battle? It's just I once tried to raise a siege unsure I'd win, and despite - as I recall - not giving the garrison break siege orders, I think they joined the battle. But I might have remembered my order wrongly.
