Less than two weeks later, there was a larger mutiny involving several regiments over pay and political demands. After the resolution of the pay issue, the Banbury mutineers, consisting of 400 soldiers with Leveller sympathies under the command of Captain William Thompson, continued to negotiate for their political demands. They set out for Salisbury in the hope of rallying support from the regiments billeted there. Cromwell launched a night attack on 13 May, in which several mutineers perished, but Captain Thompson escaped, only to be killed in another skirmish near the Diggers community at Wellingborough. The rest were imprisoned in Burford Church until three were shot in the Churchyard on 17 May. With the failure of this mutiny, the Levellers' power base in the New Model Army was destroyed.
