The Storming of Bolton, sometimes referred to as the "Bolton massacre", was an event in the First English Civil War which happened on 28 May 1644. The strongly Parliamentarian town was stormed and captured by Royalist forces under Prince Rupert. It was alleged that up to 1,600 of Bolton's defenders and inhabitants were slaughtered during and after the fighting. The "massacre at Bolton" became a staple of Parliamentarian propaganda.
