American Revolutionary War: Patriot militia units attempt to prevent capture of supply ships in and around the Savannah River by a small fleet of the Royal Navy in the Battle of the Rice Boats.

The American Revolutionary War, also known as the Revolutionary War or American War of Independence, was the armed conflict that comprised the final eight years of the broader American Revolution, in which American Patriot forces organized as the Continental Army and commanded by George Washington defeated the British Army. The conflict was fought in North America, the Caribbean, and the Atlantic Ocean. The war's outcome seemed uncertain for most of the war. But Washington and the Continental Army's decisive victory in the Siege of Yorktown in 1781 led King George III and the Kingdom of Great Britain to negotiate an end to the war in the Treaty of Paris two years later, in 1783, in which the British monarchy acknowledged the independence of the Thirteen Colonies, leading to the establishment of the United States as an independent and sovereign nation.

Patriots were colonists in the Thirteen Colonies who opposed the Kingdom of Great Britain's control and governance during the colonial era and supported and helped launch the American Revolution that ultimately established American independence. Patriot politicians led colonial opposition to British policies regarding the American colonies, eventually building support for the adoption of the Declaration of Independence, which was adopted unanimously by the Second Continental Congress on July 4, 1776.

The Savannah River is a major river in the Southeastern United States, forming most of the border between the states of Georgia and South Carolina. The river flows from the Appalachian Mountains to the Atlantic Ocean, for a total distance of about 301 miles (484 km). The Savannah was formed by the confluence of the Tugaloo River and the Seneca River. Today this confluence is part of Lake Hartwell, a man-made reservoir constructed between 1955 and 1964.
