On 16 August 1819, the day now known as the Peterloo Massacre, thousands of peaceful protestors for parliamentary reform gathered at St Peter’s Square, Manchester. Ten to twenty were killed and hundreds injured as the meeting was violently broken up by the Manchester Yeomanry, a force of volunteer soldiers. This print is one of several commemorative items produced in the aftermath of the event. It describes the Yeomanry as a 'brutal armed force' who carried out 'a wanton and furious attack' on the protestors.
