The frontier between the rebel state of Georgia and the Loyal British province of East Florida was for the first three years of the American Revolutionary War the scene of ongoing raiding. Political and military leaders in Georgia believed that East Florida's capital, St. Augustine, was vulnerable, and repeatedly promoted expeditions to capture it. The first, in 1776, fell apart when Continental Army General Charles Lee was called north shortly after it got underway. The second, in 1777, had command, supply, and logistical issues; only a company of cavalry actually entered East Florida, only to be ambushed in the Battle of Thomas Creek. Following that failure, the Georgians abandoned all their military posts south of the Satilla River.
