A seminal reference work for anyone interested in the Battle of Waterloo and the British Army of the Napoleonic period. First published in 1890, it combines a comprehensive nominal roll of British officers present at Waterloo on 18 June 1815 with biographical details, casualty information and personal anecdotes. Arranged by staff, regiment, rank and seniority, the roll provides an invaluable means of identifying individual participants. Dalton goes beyond simple military listings, recording subsequent careers, deaths and, where available, detailed obituary notices. Accounts of individual acts of courage add a valuable human dimension, bringing the experiences of officers on the battlefield to life. The work also provides useful information on the organisation and order of battle of the British and Allied Hanoverian forces, making it valuable not only for genealogical research but also for students of military organisation and the campaign itself. This substantially revised second edition of 1904 is particularly desirable. Dalton expanded the original work after acquiring a heavily annotated copy belonging to J. W. O'Brien, a researcher at the British Museum. Drawing upon additional information supplied by officers' families, this edition significantly enhances the biographical content and adds a new section devoted to non-commissioned officers and enlisted men who fought at Waterloo and were subsequently commissioned into the British Army. More than a simple roll of names, Dalton's work remains an exceptionally useful combination of military record, biography and personal history, preserving the identities and experiences of those who fought in one of the defining battles of the nineteenth century.
