Early in June, the Parliamentarian armies of the Earl of Essex and Sir William Waller threatened to surround Oxford. King Charles made a night march to escape to Worcester. He was still in danger but on 6 June, Essex and Waller (who disliked each other) conferred at Stow-on-the-Wold and fatally decided to divide their armies. While Waller continued to shadow the King, Essex marched into the West Country, to relieve Lyme which was under siege, and then to subdue Devon and Cornwall.
