The Parliamentary Army garrisoned the town upon the outbreak of the English Civil War in 1642 and established their headquarters there in June 1647 on a line from Staines to Watford,[12] although the king passed through Uxbridge in April 1646, resting at the Red Lion public house for several hours.[13] Charles I met with representatives of Parliament at the Crown Inn in Uxbridge in 1645, but negotiations for the end of hostilities were unsuccessful due in part to the king's stubborn attitude.[12] The town had been chosen as it was located between the Royal headquarters at Oxford and the Parliamentary stronghold of London.[14]
