On 16 Dec 1460 a Lancastrian force ambushed the forces of the Richard Plantagenet 3rd Duke York (age 49) near Worksop, Nottinghamshire. Andrew Trollope fought for the Lancastrians. The only source for the battle is William of Worcester's book Annales rerum Anglicarum: "In December Parliament adjourned. And the Duke of York, with the Earl of Salisbury and many thousand armed men, were going from London to York, in December 1460, when a portion of his men, the van, as is supposed, or perhaps the scouts were cut off by the people of the Duke of Somerset (age 24) at Worsop".
