These two volumes fill a large gap in the military history of the period just after the War of the Spanish Succession, in which the Duke of Marlborough had made his name. It is important to note that the British Army at the time had two establishments, the English and the Irish, and both are covered in the two volumes. Volume I covers the early Georgian period and gives much detail of the commanders and senior officers, and also includes the important listing of officers commissioned in the regiments in the English establishment in 1715. It also includes a complete listing of all non-regimental commissions, plus cavalry, artillery and ordnance commissions in 1715. The Irish officers are listed too, in a separate section, together with the officers of the Irish Train of Artillery.The second volume continues the history of the period, and gives more biographies. There is also a complete listing of officers in regiments raised in Ireland in 1715-16 and again in 1716-18. The English establishment for 1719-27 is also listed, including cavalry, guards and infantry of the line.
