when did america gain independence from the british
American Revolutionary War British attempts to disarm the Massachusetts militia in Concord led to open combat on April 19, 1775. Militia forces then besieged Boston, forcing a British evacuation in March 1776, and Congress appointed George Washington to command the Continental Army. Concurrently, an American attempt to invade Quebec and raise rebellion against the British failed decisively. On July 2, 1776, the Continental Congress voted for independence, issuing its declaration on JulyÂ 4. Sir William Howe launched a British counter-offensive, capturing New York City and leaving American morale at a low ebb. However, victories at Trenton and Princeton restored American confidence. In 1777, the British launched an invasion from Quebec under John Burgoyne, intending to isolate the New England Colonies. Instead of assisting this effort, Howe took his army on a separate campaign against Philadelphia, and Burgoyne was decisively defeated at Saratoga in October 1777.
