This is a major new examination of the Royalist armies and their role in the civil war, which is the result of ten years research. It describes and analyses the organisation, recruitment, training, arms, equipment, tactics and performance of the Royalist armies and compares them to their Parliamentarian or Roundhead couterparts. There is coverage of some of the more notable and colourful figures among the King's officers, and the reason for the Royalist defeat are also examined. It also details a variety of engagements, episodes and individuals illustrating different aspects of the Royalist armies at war. Making extensive use of contemporary source material and fully illustrated, this is an accessible and objective survey suitable for military historians, students, enthusiasts, re-enactors, wargamers and the general reader.
