On 30 December, John Williams, Archbishop of York and eleven other bishops, signed a complaint, disputing the legality of any laws passed by the Lords during their exclusion. Led by Holles, the Commons argued they were inviting the king to dissolve Parliament and thus committing treason; all twelve were arrested. On 4 January 1642, Charles tried to arrest the Five Members, including Holles, but failed and left London, accompanied by Royalist MPs like Clarendon and members of the Lords; this proved a major tactical mistake, as it gave Pym majorities in both houses.
