When the city fell, Cromwell's Army, which was enraged by events like the Portadown Massacre, made no distinction between captured soldiers and civilian noncombatants and razed even the churches where civilians took shelter. In a subsequent report to Parliament, Cromwell called the massacre "the vengeance of God against these barbarous wretches."
