The most accurate response 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 victory for the American Patriot forces over the Loyalist militia in the Carolinas. This triumph not only bolstered Patriot morale but also weakened the Loyalist presence in the region, contributing to the larger Southern Campaign during the American Revolution.
