The French Army expanded from 43 active infantry divisions, and 10 cavalry divisions in 1914 to a total of 140 divisions of infantry, and to 12 of either mounted or dismounted cavalry. The vast majority of these formations served on the Western Front in defence of France itself. Coverage includes a listing of those divisions of the Allied armies, British, American and Italian, serving under French command at various times. For each division, the authors provide a full listing of all the constituent components, whether they were infantry, artillery, cavalry or engineers, complemented by a series of detailed lists of all the metropolitan and colonial regiments from which the divisions drew their manpower. These lists cover infantry, artillery, cavalry and engineers. In the second part of the study the authors build on the coverage of divisions and regiments, providing a detailed history of higher formations of the French Army: the army groups, armies and army corps. Pour la France is destined to become a landmark reference work on World War I, as very little has been written on the subject. It is being produced in a strictly limited printing of 750 hardback copies, each individually numbered and signed by the authors.
