"Sutler" Natural Recordings by Native Speakers
A sutler is a merchant who supplies goods, especially food and other necessities, to soldiers on a battlefield or in a camp. They typically travel with an army and sell their wares at a markup, often charging high prices due to the limited competition and the soldiers' urgent need for the goods.
Unfamiliar with the word "sutling" but I found that it might be a rare or archaic term that is difficult to define.
