As the unprecedented prospect of a military confrontation between the King and Parliament grew, on 4 July 1642 Parliament voted to create a Committee of Safety consisting of ten Members of the House of Commons and five peers, of which Essex was one alongside the Earl of Northumberland, the Earl of Pembroke, the Earl of Holland and Viscount Saye and Sele. Pym, John Hampden and Denzil Holles were the leading members of the committee from the Commons. This committee was supposed to act as a bridge between Members of Parliament and the armed forces supporting them in the field. At this point these armies primarily consisted of regional defence militias and city trained bands who were sympathetic to the Parliamentary cause.
