Battle of Yorktown (1781)
British General Lord Cornwallis had fought against the Americans in 1776 and 1777. He was convinced the Americans could not defeat a British army in the field. In 1778 he returned to England to care for his wife who died in February 1779. After a few months he returned to America to continue the fight.  While he was gone, there was a change in British strategy. Before, the British had concentrated on defeating and destroying Washington's army. Now, since the French had joined the Americans, it was no longer just a rebellion but a world war.  Earlier, the French had been helping the Americans with loans and war supplies.  Now France and Spain were fighting against the British, who had to move troops from North America to defend other places.  The new strategy was to win back the Southern colonies beginning with Georgia. The British thought that as many as 50 percent of the population in the South was loyal to Britain. They would start with Georgia and move north through The Carolinas to the Virginia Colony.
