WEST POINT SAVED.--Thus left within the American lines, André crossed the river to the east shore, and started for New York by land, but was stopped by three Americans, [9] searched, and papers of great importance were found in his stockings. Despite an offer of his watch and money for his release, André was delivered to the nearest American officer, was later tried by court-martial, found guilty, and sentenced to be hanged as a spy. The American officer to whom André was delivered, not suspecting Arnold, sent the news to him as well as to Washington. Arnold received the message first; knowing that Washington was at hand, he at once procured a boat, was rowed down the river to the _Vulture_, and escaped. From then till the end of the war he served as an officer in the British army. The disasters at Charleston and Camden, and the narrow escape from disaster at West Point, made 1780 the most disheartening year of the war. KINGS MOUNTAIN.--But the tide quickly turned. After his victory at Camden, Cornwallis began to invade North Carolina, and sent Colonel Ferguson into the South Carolina highlands to enlist all the Tories he could find. As Ferguson advanced into the hill country, the backwoodsmen and mountaineers rallied from all sides, and led by Sevier, Shelby, and Williams, surrounded him and forced him to make a stand on the summit of Kings Mountain, October 7, 1780. Fighting in true Indian fashion from behind every tree and rock, they shot Ferguson's army to pieces, killed him, and forced the few survivors to surrender. This victory forced Cornwallis to put off his conquest of North Carolina. COWPENS.--General Greene was now sent to replace Gates in command of the patriot army in the South. He was too weak to attack Cornwallis, but by dividing his army and securing the aid of the partisan bands he hoped to annoy the British with raids. Morgan, who commanded one of these divisions, was so successful that Cornwallis sent Tarleton with a thousand men against him. Morgan offered battle on the grounds known as the Cowpens, and there Tarleton was routed and three fourths of his men were killed, wounded, or taken prisoners. [Illustration: BATTLE OF THE COWPENS.] THE GREAT RETREAT.--This victory won, Morgan set off to join Greene, with Cornwallis himself in hot pursuit. When Greene heard the news, he determined to draw the British general far northward and then fight him wherever he would be at most disadvantage. [10] The retreat of the American army was therefore continued to the border of Virginia.
