On 23 July 1793 the Prussian army successfully ended the Siege of Mainz. The Prussians thoughtlessly allowed the 16,000-man French garrison to go home on the condition not to fight against the Coalition for one year. "Army of the Rhine" commander Alexandre de Beauharnais suggested that using the garrison to fight in the Vendée would not be a violation of their parole. By 25 August the so-called "Army of Mayence" (the French name for Mainz) under Jean-Baptiste Annibal Aubert du Bayet assembled at Tours. Its 14,000 well-trained troops included Jean Baptiste Kléber newly promoted to general of brigade. The Austrians and English having made the same blunder as the Prussians, the 6,000 fit troops from the garrison of Valenciennes were sent first to the Siege of Lyon and later to the Vendée.
