Following the loss of Savannah, American forces withdrew to Charleston, South Carolina. On May 12, 1780, after both a battle and a siege, Henry Clinton secured the city. He quickly took Augusta and set up a semi-circle of forts between Augusta and Charleston to protect his position. Georgians began to leave the state because of the British rule. Among those who depart is Lyman Hall, signer of the Declaration of Independence. A wanted man by the British in the state of Georgia, he flees to Connecticut, where he is not well known. The British destroy his property in both Savannah and Sunbury.
Georgians began a resistance movement aimed at disrupting the British presence and got pretty good at it. On the Ogeechee, rice boats were frequent targets as was British shipping along Georgia's coast. Upcountry farmers who did not accept Clinton's offer of amnesty continued to bedevil the British and the Georgia government-in-exile met at Fort Heard. Elijah Clarke briefly suspended his military activities so that he could lead a group of 400 women and children to safety in the mountains of East Tennessee.
On his return, Clarke became determined to rid upcountry Georgia of the British invaders. In September, 1780 he launched an attack against Augusta only to fail when the British re-enforced the city from Fort Ninety-Six. Georgia prisoners suffered horribly at the hands of Colonel James Grierson. With his forces depleted and a crop in the field, Clarke was forced to withdraw.
