The siege of Gloucester took place between 10 August and 5 September 1643 during the First English Civil War. It was part of a Royalist campaign led by King Charles I to take control of the Severn Valley from the Parliamentarians. Following the costly storming of Bristol on 26 July, Charles invested Gloucester in the hope that a show of force would prompt it to surrender quickly and without bloodshed. When the city, under the governorship of Lieutenant-Colonel Edward Massey, refused, the Royalists attempted to bombard it into submission. Massey adopted an aggressive defence, and the Royalist positions outside the city were regularly disrupted by Parliamentarian raids. The Royalist artillery proved inadequate for the task of siege work and, faced with a shortage of ammunition, the besiegers attempted to breach the city walls by mining. With Royalist miners about to reach the city's east gate and the defenders critically low on gunpowder, a Parliamentarian army led by the Earl of Essex arrived and forced Charles to lift the siege.
