The county of Cornwall in the far south-west of England is surrounded by sea on three sides. Resisting Roman and Anglo-Saxon invaders, it retained its Celtic independence and remained separate from the rest of England into the Middle Ages. Cornwall has a rich military history that stretches back through centuries, and evidence of this military heritage can be seen throughout the county with numerous buildings and other structures still standing today. Cornwall's Military Heritage explores the history of the county - not only the battles that took place on its soil and the measures that were taken to defend it, but also the heritage of the military units that were nurtured there and sent to fight in conflicts abroad. Cornwall was home to two uprisings in 1497, followed by the Prayer Book Rebellion in 1549 and the Spanish raiding of 1595. In the English Civil War, Cornwall was a Royalist stronghold in the predominantly Parliamentarian South West, and Pendennis Castle was besieged alongside the strategic Isles of Scilly, contested by both sides. Author Andrew Powell-Thomas explores the conflicts surrounding an array of historic monuments, including castles, forts, airfields and military bases, noting how the Duke of Cornwall's Light Infantry and its antecedents fought through two world wars to maintain the survival of this most remarkable county.
