The negotiations between the army and Parliament were acrimonious. Mobs in Presbyterian-dominated London threatened Vane and other Independents. More than 50 Independent MPs, Vane among them, fled the city on 2 August for the protection of the army. The army then marched on London, with Vane and others at its head, and the Independents were again seated in Parliament. The Parliament then debated the army's "Heads of Proposals" for fixing the term and powers of Parliament and church governance. Key among its terms of interest to Vane was one that effectively stripped the church, either Episcopal or Presbyterian, of any coercive powers. The "Heads of Proposals" was also sent to Charles, who indicated agreement to some of its terms and opposition to others, and proposed further negotiations.
