In the Irish Brigade by G. A. Henty

Historical novel, set in the early 18th century. From the Preface: For records of the doings of some of the regiments of the Irish Brigade, during the years 1706-1710, I am indebted to the painstaking account of the Irish Brigade in the service of France, by J. C. OCallaghan; while the accounts of the war in Spain are drawn from the official report, given in Boyers Annals of the Reign of Queen Anne, which contains a mine of information of the military and civil events of the time.
