In the Siege of Mainz , from 14 April to 23 July 1793, a coalition of Prussia, Austria, and other German states besieged and captured Mainz from revolutionary French forces. The allies, especially the Prussians, first tried negotiations, but this failed, and the bombardment of the city began on the night of 17 June.
Within the town the siege and bombardment led to stress between citizens, municipality and the French war council, governing since 2 April. The city administration was displaced on 13 July; this increased the stubbornness of the remaining population. Since a relief army was missing, the war council was forced to take up negotiations with the allied forces on 17 July; the remaining soldiers capitulated on 23 July.
