The conclusion sets out the key points and arguments of the individual chapters to demonstrate the benefit of adopting a transatlantic approach to understanding British imperialism and the outbreak of the American Revolution. It summarises the impact of the Forty-Five on the British army as it waged war, pacified hostile peoples, and implemented militarisation strategy in North America and highlights how militarisation affected the attitudes of military officers during a transformative period of imperial expansion. The conclusion emphasises the important role military commanders played in imperial governance, not simply implementing policy decisions taken at Whitehall but actively shaping such decisions. It argues that the army, therefore, played a material role in the coming of the revolution.
