Washington planned an attack on Germany to get back at them for the Battle for New York City loss. Around 4,000 Americans crossed the frozen Delaware River to win the Battle of Trenton.
Battle of Yorktown 1781
Britain had to clear the way on their march to Saratoga Springs. When they got there, militia troops were already there. Surrounded, British General Burgoyne surrendered on October 17, 1777.
Washington trained his army men hard, although around 2,500 of them had died from disease in winter. The army was ready when the British went back to New York City from Philadelphia, where they had been since 1777. The Americans won the battle in New Jersey in June 1778.
American troops stayed close behind Britain and the 2 armies became involved in a fighting style later called "guerrilla warfare." Americans would frustrate Brits by attacking without warning then going back into hiding. This caused Britain to go to Yorktown, Virginia. America soon followed with the French. The Battle of Yorktown started on October 6, 1781 and ended on October 19, 1781 with Britain surrendering to the 16,000 troops.
