On the pivotal day of 14 June 1645 Charles I's Royalist Army and Parliament's New Model Army made battle at Naseby. Using first-hand accounts, Martin Marix Evans introduces the origins of the campaign, explores the strengths and weaknesses of the opposing armies, and vividly describes the engagement. The traditional condemnation of Prince Rupert's military strategy is undermined, and the significance of Okey's Dragoons in precipitating the action explained. He imparts his intimate knowledge of the terrain so crucial to the New Model Army's frontage, and uses archaeological and documentary evidence to piece together a remarkable blow-by-blow account of this devastating battle.
