Answer 1

Some buying from and strong arming the locals. Plenty of stealing, looting, pillaging. Then there was the massive troupe of people who would follow the army, they weren’t employed by them, and would sell services of all kinds, goods and wares. Where the army went there was to be money so people and traders would follow the campaign. It was apparently very profitable however risky.
