The new state legislature met the next December to complete the state constitution made the previous October, de-establishing the Anglican Church. In the Upcountry, the British had convinced the Cherokee to fight on their side. Although the British officer in charge of the operation had told the Cherokee to attack only Patriot soldiers in organized groups, soon murder and cabin burnings were widespread on the frontier. The Whigs' Andrew Williamson, Andrew Pickens, and James Williams, who had been battling Loyalists in the Upcountry, launched a successful campaign against the Cherokee. In 1777 they ceded their remaining lands to the South Carolina government. On February 5, 1778, South Carolina became the first state to ratify the Articles of Confederation, the first constitution of the United States. In 1780, the British returned to South Carolina.
