Question

How did the loyalists treat the patriots during the war

Answer 1

Any full assessment of the American Revolution must try to understand the place of Loyalists, those Americans who remained faithful to the British Empire during the war. ... Unless the British Army was close at hand to protect Loyalists, they often suffered badtreatment from Patriots and often had to flee their own homes.

Answer 2

They were not treated well at all. Some got their houses vandalized or burned. Others were beaten or got tar and feathered (when people striped others, poured hot tar on them and covered them in chicken feathers. Most people did not survive this). After the war, the Loyalists were kicked out of the country and went off to British Canada.
