The Battle of Brier Creek was an American Revolutionary War battle fought on March 3, 1779 near the confluence of Brier Creek with the Savannah River in eastern Georgia. A mixed Patriot force consisting principally of militia from North Carolina and Georgia along with some Continental regulars was defeated, suffering significant casualties. The rout damaged Patriot morale.

The Continental Army was the army of the Thirteen Colonies and the Revolutionary-era United States. It was formed by the Second Continental Congress after the outbreak of the American Revolutionary War, and was established by a resolution of Congress on June 14, 1775. The Continental Army was created to coordinate military efforts of the Colonies in their war for independence. General George Washington was the commander-in-chief of the army throughout the war.

The Continental Army was supplemented by local militias and volunteer troops that were either loyal to individual states or otherwise independent. Most of the Continental Army was disbanded in 1783, after the Treaty of Paris formally ended the fighting. The 1st and 2nd Regiments of the Army went on to form what was to become the Legion of the United States in 1792. This became the foundation of what is now the United States Army.
