The Banbury mutiny was a mutiny by soldiers in the English New Model Army. The mutineers did not achieve all of their aims and some of the leaders were executed shortly afterwards on 17 May 1649.
The mutiny was over pay and political demands. The pay issue was defused by Oliver Cromwell acknowledging the justice of the soldiers' financial grievances and securing £10,000 towards payment of arrears from Parliament. But 400 troopers under the command of Captain William Thompson who were sympathetic to the Levellers set off from Banbury, where they were billeted to speak with other regiments at Salisbury about their political demands.
Major White was sent by Cromwell and Thomas Fairfax to mediate with Thompson's troops and give assurances that force would not be used against them. However on 13 May Cromwell launched a night attack. Several mutineers were killed in the skirmish. Captain Thompson escaped only to be killed a few days later in another skirmish near the Diggers community at Wellingborough. After being imprisoned in Burford Church with the other mutineers, three other leaders were shot: Cornet James Thompson (William Thompson's brother), Corporal Perkins and John Church on 17 May 1649. This destroyed the Levellers' power base in the New Model Army.
