For the campaigns in the West Indies the original despatches in the Record Office have afforded most material, supplemented by a certain number of small pamphlets in the British Museum. The Maroon War is treated with great fulness by Dallas in his _History of the Maroons_; and there is matter also in Bridges’ _Annals of Jamaica_, and the works of Bryan Edwards. The original despatches are, however, indispensable to a right understanding of the war. Unfortunately the despatches that relate to St. Domingo are not to be found at the Record Office, so that I have been compelled to fall back on the few that are published in the _London Gazette_. Nor could I find any documents relating to the return of the Regiment from the West Indies, which has forced me unwillingly to accept the bald statement in Cannon’s records. The raid on Ostend and the expedition to La Plata have been related mainly from the accounts in the original despatches, and from the reports of the courts-martial on General Whitelocke and Sir Home Popham. There is much interesting information as to South America,--original memoranda by Miranda, Popham, Sir Arthur Wellesley (the Duke of Wellington) and other documents--preserved among the manuscripts at Dropmore. The dearth of original documents both at the Record Office and the India Office has seriously hampered me in tracing the history of the Regiment during its first sojourn in India and through the Pindari War. I have, however, to thank the officials of the Record Department of the India Office for the ready courtesy with which they disinterred every paper, in print or manuscript, which could be of service to me. Respecting the Crimea and the Indian Mutiny I have received (setting aside the standard histories) much help from former officers, notably Sir Robert White, Sir William Gordon, and Sir Drury Lowe, but especially from Sir Evelyn Wood, who kindly found time, amid all the pressure of his official duties, to give me many interesting particulars respecting the chase of Tantia Topee. Above all I have to thank Colonel John Brown for information and assistance on a hundred points. His long experience and his accurate memory, quickened but not clouded by his intense attachment to his old regiment, have been of the greatest value to me. My thanks are also due to the officials of the Record Department of the War Office, and to Mr. S. M. Milne of Calverley House, Leeds, for help on divers minute but troublesome points, and to Captain Anstruther of the Seventeenth Lancers for constant information and advice. Lastly, and principally, let me express my deep obligations to Mr. Hubert Hall for his unwearied courtesy and invaluable guidance through the paper labyrinth of the Record Office, and to Mr. G. K. Fortescue, the Superintendent of the Reading-Room at the British Museum, for help rendered twice inestimable by the kindness wherewith it was bestowed.
