A revolt began brewing in Lyon on 29 May 1793. As early as 8 July, the representative Edmond Louis Alexis Dubois-Crancé wanted Kellermann to lead his army to Lyon, but the commander insisted on a written order. The leading Jacobin of Lyon, Joseph Chalier had a guillotine sent to that city from Paris. He planned to execute 900 counter-revolutionaries in Lyon, but he was seized instead. On 18 July, Chalier became a victim of his own guillotine. On 20 July, the National Convention ordered Kellermann to put down the revolt in Lyon. The general was reluctant, pointing out that moving against Lyon would cause him to remove troops needed to defend the Alpine border. Nevertheless, Kellermann set out with 10,000 infantry and 3,000 cavalry on 6 August. Eventually, 28,000 troops were required to bring the Siege of Lyon to a conclusion.
