First Newbury: Order of Battle

The first battle of Newbury was fought on 20 September 1643. The Earl of Essex had marched his army and a brigade of London Trained Bands to Gloucester, which was besieged by the King's Oxford army. Having lifted the siege, Essex marched back towards London. The King's army marched in pursuit and intercepted the Parliamentarians at Newbury in Berkshire. With the route back to London blocked by the Royalists, Essex was forced to fight a battle he had hoped to avoid. Neither side gained a clear victory but the Royalists ran short of gunpowder and were forced to withdraw, allowing the Parliamentarians to complete their march to London.
