The military aspects of the Jacobite campaigns in eighteenth-century Britain are considered in this study. Taken from the viewpoint of those loyal to the Hanoverian Crown, the three mainland campaigns of 1715–6, 1719 and 1745–6 are examined, using research based on primary sources: memoirs, diaries, letters, newspapers and state papers. Oates looks at how the eighteenth-century military machine operated in a domestic context, as well as its effectiveness. Such a focus adds a new dimension to the study of this period, and allows for further questions as to the uniqueness of the Jacobite rebellions.
