Also as others have pointed out, I think you'd be surprised how difficult and slow it is to carry heavy army-supplying loads over a winding network of unimproved trails that periodically get flooded out or turn to mud, all while being assailed by bandits and toll collectors. Travel in that era was not only slow and expensive, but risky.
