That was very different. Armies then lived off the land, bought/stole what they needed very locally. Yes. It was the medieval version of logistics -- basically everything comes from the immediate vicinity and there's frack-all by comparison for infrastructure. You could have supply lines, but it was proportionally more expensive. It's quite surprising, the amount of materials for building a castle which came from the immediate vicinity. Sieges were not that common. Like battles were even less common. I was given to understand that sieges were more frequent than battles.
