In June–July 1793, Bordeaux, Marseilles, Brittany, Caen and the rest of Normandy gathered armies to march on Paris and against 'the revolution'. In July, Lyon guillotined the deposed 'Montagnard' head of the city council. Barère, member of the Committee of Public Safety, on 1 August incited the convention to tougher measures against the Vendée, at war with Paris since March: "We'll have peace only when no Vendée remains… we'll have to exterminate that rebellious people". In August, Convention troops besieged Lyon.
