Having in the Preface stated the plan of this volume, it is incumbent on the Author now to acknowledge, with gratitude, the assistance he has received during its execution. Acting on a suggestion made by one of the reviewers of the first volume, he has noted in the margin the various authorities on which the narrative is based; and, as in many instances these are manuscript letters in the Record Office, he has given the dates of such,--to facilitate access to them by any one anxious to obtain information in detail. Among those to whom the Author is chiefly indebted, Sir Collingwood Dickson--for the reason stated in the body of the work--stands first. Not only the Author, but the Regiment at large, is indebted to him for the generous confidence with which he entrusted the letters and journals of his distinguished father to the writer of this history. The labours of Captain G. E. W. Malet, R.A.--so visible in the tables at the end of this volume--demand the next place in the Author’s acknowledgment;--and the Reader will be able to judge how great has been the value, to this narrative, of the published writings of Captain H. W. L. Hime, R.A. Sir J. Bloomfield, Sir E. C. Warde, Sir D. E. Wood, General Burke Cuppage, Major-Generals W. J. Smythe and C. J. B. Riddell, Colonel Lynedoch Gardiner, Major H. Geary, and Lieutenant J. Ritchie, have contributed valuable information connected with the history of the Regiment to which they belong, and have greatly facilitated the Author’s labours. The assistance of Sir Edward Perrott, and of Captain H. W. Gordon, C.B., is also gratefully acknowledged. To Mr. James Browne, the author of ‘England’s Artillerymen’ a double debt is owing. His labour produced the Index to the first volume; and his published work has been a mine of reference, the value of which became more apparent, the more it was explored. Written without the adventitious aids at the disposal of the custodian of the Regimental Records, it is yet so exhaustive and accurate, that, when admiration of it has ceased, it is only because that feeling has passed into envy. The admirable Index to the present volume is due to the skill, ability, and industry, eminently possessed by the Assistant-Superintendent in the Record Office, R. H. Murdoch, Esq., R.A. These talents were generously placed at the Author’s disposal, with a view to this work being made as complete as possible.
