Trouble began again in 1790, the year of the civil uprising that eventually led to the United States of Belgium. The Austrians occupied the city, were forced out by the French after the Battle of Jemappes on 6 November 1792, and took it back again four months later. On 12 June 1794, the French revolutionary Army of Sambre-et-Meuse under the command of Jean-Baptiste Jourdan, invested Charleroi and won a decisive victory in the ensuing Battle of Fleurus. The city took the revolutionary name of Libre-sur-Sambre until 1800. After France's defeat in 1814, the whole area was annexed to the Netherlands, and new walls were built around the city. Napoleon stayed in Charleroi for a couple of days in June 1815, just before the Battle of Waterloo.
