The British shifted their armies southward in 1779, hoping to cut off the lower southern states, break the morale of the rest of America, and force a negotiated peace. Their principal hopes rested on exploiting loyalist strength in the fiercely divided Carolinas where much of the fighting since 1775 had been colonial against colonial, patriot against Tory. In early 1780 General Henry Clinton sailed from New York with 8,000 troops, outmaneuvered General Benjamin Lincoln, and captured Charleston. The defeat was a severe blow to the Americans costing them their chief southern seaport, several thousand Continentals and militiamen from the Carolinas and Virginia, and Generals Lincoln and William Woodford.
Clinton sailed back to New York, leaving his troops with Lord Cornwallis. The most daring of the British generals, Cornwallis decided to leave Charleston and invade the Carolinas. With excellent support from Colonel Banastre Tarleton, Lord Rawdon, and Major Patrick Ferguson he swept all before him. Tarleton, the best cavalry officer in either army, and Ferguson led partisan loyalist units. Tarleton's troopers, known as the British Tory Legion, needed no introduction to Virginians. They had slaughtered without quarter unarmed Virginians under Colonel Abraham Buford in May 1780 at the Waxhaws, south of Charlotte, North Carolina. From then on he was known as "Bloody Tarleton".
Congress elected Horatio Gates to replace Lincoln in the southern command. Gates hurried south with several thousand Maryland, Virginia, and North Carolina militiamen and Continental troops. Stumbling into Cornwallis' army at Camden, South Carolina, he planned and executed a faulty battle plan. Cornwallis executed perfectly and completely routed Gates. For the only time in the war Virginia militiamen behaved badly, fled the field, and were a major contributing factor to the disaster. Not only did Gates lose 600 men, many of them battle-hardened Continentals, he lost two outstanding officers, General Jean de Kalb, the tough German officer, and Colonel Edward Porterfield from Virginia. Facing almost sure defeat in the Carolinas, Congress replaced Gates with Nathaniel Greene of Rhode Island, taking care not to embarrass the Englishman who had given so much to Patriot cause.
