Graham Turner is a leading historical artist, specialising in the medieval period.

The son of the illustrator Michael Turner, Graham lives and works in Buckinghamshire, UK.

At the crescendo of the Second Barons' War were the battles of Lewes and Evesham. It was an era of high drama and intrigue, as tensions between crown and aristocracy had boiled over and a civil war erupted that would shape the future of English government. In this detailed study, Richard Brooks unravels the remarkable events of the battles of Lewes and Evesham, revealing the unusually tactical nature of the fighting, in sharp contrast to most medieval conflicts which were habitually settled by burning and ravaging. At Lewes, Simon de Montfort, the powerful renegade leader of the Baronial faction, won a vital victory, smashing the Royalist forces and capturing Henry III and Prince Edward. Edward escaped, however, to lead the Royalist armies to a crushing victory just a year later at Evesham. Using full colour illustrations, bird's-eye views and detailed maps to generate an arresting visual perspective of the fighting, this book tells the full story of the battles of Lewes and Evesham, the only pitched battles to be fought by English armies in the mid-13th century.
