The Siege of Savannah or the Second Battle of Savannah was an encounter of the American Revolutionary War in 1779. The year before, the city of Savannah, Georgia, had been captured by a British expeditionary corps under Lieutenant-Colonel Archibald Campbell. The siege itself consisted of a joint Franco-American attempt to retake Savannah, from September 16 to October 18, 1779. On October 9 a major assault against the British siege works failed.
