Charles I passed through Southam just before the outbreak of the Civil War and apparently was not made welcome by the townsfolk, who refused to ring the parish church bells. On 23 August 1642, the day after King Charles 1st formally declared war on Parliament, a skirmish was fought outside the town between Parliamentary forces led by Lord Brooke and Royalist forces commanded by the Earl of Northampton. The Battle of Southam is claimed by locals to have been the first battle of the English Civil Wars. Later that year, Charles stayed in Southam before the Battle of Edgehill on 23 October 1642. In 1645 Oliver Cromwell and 7,000 Parliamentary troops stayed in the town.
