The American Revolution officially came to an end when
representatives of the United States, Great Britain, Spain
and France sign the Treaty of Paris on September 3, 1783.

The signing signified America’s status as a free nation, as
Britain formally recognized the independence of its 13
former American colonies, and the boundaries of the new
republic were agreed upon: Florida north to the Great
Lakes and the Atlantic coast west to the Mississippi
River.

The American flag was flown in battle for the first time on this day
in 1777, during a Revolutionary War skirmish at Cooch’s Bridge, Delaware. Patriot General William Maxwell ordered the stars and
stripes banner raised as a detachment of his infantry and cavalry
met an advance guard of British and Hessian troops.

The rebels were defeated and forced to retreat to General George Washington’s main force near Brandywine Creek in Pennsylvania.
