When Charles Stuart was crowned King of Scotland, Cromwell led the English army north to counter the threat he now posed. Their march on Edinburgh was opposed by Leslie's Scottish army who used guerrilla tactics to force them back as far as Dunbar. Battle ensued on 3 September 1650, and the Scots fought with great determination until Cromwell led his cavalry against their right wing. The Scots army crumbled from right to left, and was driven from the field. Leslie retreated and Cromwell captured Edinburgh, although the war continued for another year after this crushing English victory.
