Gunpowder Plot [SEP] Introduction
Most of the conspirators fled from London as they learned of the plot's discovery, trying to enlist support along the way. Several made a stand against the pursuing Sheriff of Worcester and his men at Holbeche House; in the ensuing battle, Catesby was one of those shot and killed. At their trial on 27 January 1606, eight of the survivors, including Fawkes, were convicted and sentenced to be hanged, drawn and quartered.
