The Battle of Cropredy Bridge was a battle of the English Civil Wars, fought on 29 June 1644 between a Parliamentarian army under Sir William Waller and the Royalist army of King Charles. After a Parliamentarian attack on the Royalist rearguard was repulsed, Waller's army became demoralised and ineffective, allowing the King to retrieve the Royalists' fortunes after other defeats during the earlier part of the year.
