The correct answer is: The win was a great boost to Patriot morale and the Loyalists of the Carolina Back Country were broken as a military force.
The Battle of King's Mountain, fought on October 7, 1780, was a significant Patriot victory in the southern campaign of the American Revolutionary War. It not only bolstered the morale of the American forces but also significantly weakened Loyalist support in the region, which helped shift the momentum in favor of the Patriots.
