The British Army during the American Revolutionary War served for eight years in the American Revolutionary War, which was fought throughout North America, the Caribbean, and elsewhere from April 19, 1775, to September 3, 1783. The war formally commenced at the Battles of Lexington and Concord in present-day Massachusetts. Two months later, in June 1775, the Second Continental Congress, gathered in the revolutionary capital of Philadelphia, appointed George Washington to organize patriot militias into the Continental Army and lead them in a war against the British Army. The following year, in July 1776, the Second Continental Congress, representing the Thirteen Colonies, declared themselves free and independent from colonial governance.

The American Revolutionary War, also known as the Revolutionary War or American War of Independence, was a military conflict that was part of the broader American Revolution, where American Patriot forces organized as the Continental Army and commanded by George Washington defeated the British Army.
