Military activity was central to Anglo-Scots relations in the first half of the sixteenth century, playing an important role in the formation of the multi-national Tudor state and the process of political union. This book examines both the organisational nature of the two nations' military establishments and provides a detailed operational study of military activity. It challenges notions that the British Isles were peripheral to the trends of mainstream continental warfare through a detailed study of the manner in which both Scottish and English armies demonstrated a commitment to tactical and technological development. The failure of both nations to come up with effective strategies or conclusive successes is addressed, and contributory causes identified. The major engagements at Flodden (1513), Solway Moss (1542) and Pinkie (1547) are examined; attention is also paid to the everyday routines of military activity: garrison duty, chevauchee and siege work.
