First Battle of Newbury
The First Battle of Newbury was a battle of the First English Civil War that was fought on 20 September 1643 between a Royalist army, under the personal command of King Charles, and a Parliamentarian force led by the Earl of Essex. Following a year of Royalist successes in which they took Banbury, Oxford and Reading without conflict before storming Bristol, the Parliamentarians were left without an effective army in the west of England. When Charles laid siege to Gloucester, Parliament was forced to muster a force under Essex with which to beat Charles' forces off. After a long march, Essex surprised the Royalists and forced them away from Gloucester before beginning a retreat to London. Charles rallied his forces and pursued Essex, overtaking the Parliamentarian army at Newbury and forcing them to march past the Royalist force to continue their retreat.
