The Battle of Powick Bridge was a skirmish fought on 23 September 1642 just south of Worcester, England, during the First English Civil War. It was the first engagement between elements of the principal field armies of the Royalists and Parliamentarians. Sir John Byron was escorting a Royalist convoy of valuables from Oxford to King Charles's army in Shrewsbury and, worried about the proximity of the Parliamentarians, took refuge in Worcester on 16 September to await reinforcements. The Royalists despatched a force commanded by Prince Rupert. Meanwhile, the Parliamentarians sent a detachment, under Colonel John Brown, to try to capture the convoy. Each force consisted of around 1,000 mounted troops, a mix of cavalry and dragoons.
