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.
