What events at kings mountain caused formerly neutral colonists to support the patriots?

By eighteenth-century standards, the American Revolution was very radical. For the first time, overseas colonies banned their empire to create a republican union. In late 1778, they grasped Savannah, Georgia. During the spring of 1780, they seized Charleston, South Carolina - along with 5,000 Patriot soldiers. That summer, the British crushed another Patriot army at Camden, South Carolina. In 1780, they arrested the British fort at Mobile, Alabama. The next year, they took Pensacola, the capital of British West Florida. In October 1780, at Kings Mountain in South Carolina, the Patriots crushed a Loyalist militia and killed many of the prisoners. As the Loyalists lost men and ground, neutral civilians swung over to the Patriot side.

Why do you have to ask such hard questions.
