Something that fascinates me about ancient battles, is armies numbers. In movies, even in supposedly huge battles, we are actually only shown a few thousands troops (at most) during those aerial shots from above, and they always look like a compact single group of men. Trying to visualize how armies of 15, 50 or even 100 thousands soldiers would actually look is pretty difficult and crazy, I imagine that in a moving column they would occupy miles and miles of roads, withouth counting all the supply wagons and stuff, and in a campal battle they would stretch to the horizon.
So getting back to the original question: while I can imagine all those troops setting up huge camps in the open, I can't visualize 10-15k soldiers stashed behind the walls of a (smaller) medieval city with no big open spaces. Did they camped in streets, or city squares? did they occupy the invididual homes of the inhabitants? where they always armed and ready to fight off an attack? Was every space between buildings crowded with soldiers? Basically, all the logistic problems of sustaining a big army, amplified by the fact that they're in a closed space filled with buildings and civlians I guess
I hope this makes sense and thanks in advance!
