Clock The tale about St. Pauls clock striking thirteen is given in Walcotts Memorials of Westminster, and refers to John Hatfield, who died 1770, aged 102. He was a soldier in the reign of William III, and was brought before a court-martial for falling asleep on duty upon Windsor Terrace. In proof of his innocence he asserted that he heard St. Pauls clock strike thirteen, which statement was confirmed by several witnesses.
