After relieving Gloucester in September 1643, Essex was shadowed on his return journey to London by Charles's army. The royalists reached Newbury a few hours before their opponents, cutting off the retreat. The king's army was some 10,000 men, Essex's perhaps a little less. On 20 September battle commenced with an artillery exchange but the fighting, though heavy, was inconclusive. Charles, short of ammunition, was obliged to withdraw to Oxford, leaving Essex free to return to the capital.
