Osprey's examination of the British cavalry during the English Civil War (1642-1651). In March 1642, King Charles I, believing that Parliament had gone too far when it issued the Grand Remonstrace, moved to arrest John Pym and four other leaders. That summer Parliament, fearing military action, tried to seize control of the army by issuing orders for soldiers to report to Parliamentary, rather than royal, representatives. The King countered by ordering the bill ignored and raised his own army. Some turned out for the King, some for Parliament, and so the war started. This book examines how the cavalry soldiers of 1642 expected to fight the Civil Wars, and how experience changed their ideas.
