Query: Where did John march from?
Context: In September 1216 John began a fresh, vigorous attack. He marched from the Cotswolds, feigned an offensive to relieve the besieged Windsor Castle, and attacked eastwards around London to Cambridge to separate the rebel-held areas of Lincolnshire and East Anglia. From there he travelled north to relieve the rebel siege at Lincoln and back east to King's Lynn, probably to order further supplies from the continent.[nb 17]
