The materials for the following "Life of Field-Marshal Lord Seaton" are drawn (1) from his own letters and those of his wife and his friends, (2) from reports taken down by his daughters (from about 1847 onwards) of his spoken references to events in which he took part, (3) from the recollections of persons now living, (4) from published works.<br><br>For the use of letters, I am indebted in the first place to the Hon. Lady Montgomery-Moore, whose anxiety to see some such monument raised to her revered father's memory was my first encouragement towards undertaking this work; and secondly to the Lord Seaton, to Lieutenant-Colonel the Hon. F. L. Colborne, to Miss Mary Yonge of Yealmpton, to John Yonge, Esq., of Puslinch, to Miss H. E. Yonge of Eastleigh, Hants, to the Hon. W. N. Bruce, grandson of Sir William Napier, and to Lieutenant-Colonel A. F. Mockler-Ferryman, Oxfordshire Light Infantry, who, one and all, put the letters and memoranda which were in their possession at my disposal. I have also to thank Field-Marshal H.R.H. the Duke of Cambridge for permission to publish two of his letters addressed to Lord Seaton.<br><br>For the portraits and other illustrations given in this book, I am indebted to His Grace the Duke of Wellington, the Lord Seaton, General Sir Alexander and the Hon. Lady Montgomery-Moore, the Hon. and Rev. Graham Colborne, Colonel the Hon. F. L. Colborne, and John Yonge, Esq., of Puslinch.<br><br>In the course of my work I have received most valuable assistance and criticism from many sources.
