 In December 1641, Sir Arthur Haselrige introduced a militia bill giving Parliament the right to nominate its commanders, not Charles, which was passed by the House of Commons.After failing to arrest the Five Members on 5 January, Charles left London, and headed north to York; over the next few weeks, many Royalist members of the Commons and House of Lords joined him.The result was a Parliamentary majority in the Lords, who approved the bill on 5 March 1642, while confirming doing so was not a violation of the Oath of Allegiance.
