Torin, perhaps you are thinking of what happens when you storm a castle -- if a 3rd army moves into the province and you stormed with your entire force, then that 3rd army will be sieging you.

Or maybe if the defending party throws some magic movement commandos on the sieging army while they get reinforcements. The teleported army will defeat the sieging army outside, then get inside to snuggle with the others, while the reinforcements siege again.

I don't think that there are extra phases involved in sieging that are not in the manual. As I wrote, siege break is a zero distance movement, that's all. The process is very deterministic, somebody go forward and draw a nice chart.
