The Capture of Savannah was an American Revolutionary War battle fought on December 29, 1778 pitting local American Patriot militia and Continental Army units, holding the city, against a British invasion force, commanded by Lieutenant Colonel Archibald Campbell. The British capture of the city led to an extended occupation and was the opening move in the British southern strategy to regain control of the rebellious Southern provinces by appealing to the relatively strong Loyalist sentiment there.

General Sir Henry Clinton, the Commander-in-Chief, North America, dispatched Campbell and a 3,100-strong force from New York City to capture Savannah, and begin the process of returning Georgia to British control. He was to be assisted by troops under the command of Brigadier General Augustine Prevost that were marching up from Saint Augustine in East Florida. After landing near Savannah on December 23, Campbell assessed the American defenses, which were comparatively weak, and decided to attack without waiting for Prevost. Taking advantage of local assistance he flanked the American position outside the city, captured a large portion of Major General Robert Howe's army, and drove the remnants to retreat into South Carolina.

Campbell and Prevost followed up the victory with the capture of Sunbury and an expedition to Augusta. The latter was occupied by Campbell only for a few weeks before he retreated to Savannah, citing insufficient Loyalist and Native American support and the threat of Patriot forces across the Savannah River in South Carolina. The British held off a Franco-American siege in 1779, and held the city until late in the war.
