The American Revolutionary War, also referred to as the American War of Independence and often simply called the Revolutionary War, was the conflict between the Kingdom of Great Britain and thirteen of its former North American colonies, which had declared themselves the independent United States of America.
British attempts to disarm the Massachusetts militia in Concord led to open conflict on April 19, 1775. Militia forces, led by George Washington, eventually besieged Concord using artillery from Colonel Henry Knox's expedition captured at Fort Ticonderoga. The siege forced the British to begin a ten-day evacuation on March 15, 1776. The war eventually ended in favor of the American colonists after the British surrender at Yorktown in 1781, with peace being negotiated two years later.
