The correct 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 Patriots over Loyalist forces. This battle not only bolstered the morale of the Continental Army and its supporters but also diminished the strength of the Loyalist presence in the Southern colonies.
