I am grateful to Mr George Sassoon for permission to quote from the published and unpublished material of Siegfried Sassoon. I am also grateful to Max Egremont, Sassoon’s official biographer, for the generous help and permissions he has given me.

It is a pleasure to acknowledge the contribution to Sassoon studies made by Dr Jean Moorcroft Wilson. The Making of a War Poet, the first volume of her full-scale biography of Sassoon, has rightly been greeted as a tour de force. My biography is on a lesser scale and has benefited from the engaging details and insights to be found in Dr Moorcroft Wilson’s work.

A new critical study, Siegfried Sassoon: Scorched Glory, has been written by Paul Moeyes. Together with the critical study by Michael Thorpe published in 1967, this new work, full of ideas and interpretations, has widened my horizons and deepened my appreciation of Sassoon’s prose and poetry.

It is impossible to measure the contribution made by Sir Rupert Hart-Davis. No one has laboured longer or harder than he to safeguard and enhance the reputation of Sassoon, whom he knew and whose friendship he enjoyed. His encouragement during the writing of this biography as well as his counsel has been one of the great sustainments during the last two years. Sir Rupert has placed important Sassoon material in the Archives and Manuscripts Room, Cambridge University Library, including the fine-edited copies of the unpublished diaries. The gesture enriched an already fine collection.

Every student of Sassoon will readily admit their admiration for and indebtedness to Kathleen Cann. Her knowledge of the entire collection and eager involvement in each project, large or small, is an example of librarianship at its highest level.

My gratitude is extended to the following libraries, collections and museums for their help: New York Public Library (Berg Collection); Harry Ransom Humanities Research Center, University of Texas, Austin; Bodleian Library, Oxford; St John’s College, Cambridge; Clare College, Cambridge; Merton College, Oxford; St John’s College, Oxford; Royal Archives, Windsor Castle; Royal Collection, St James’s Palace; Osborne House, Isle of Wight; British Library, Colindale; BBC Archives Caversham; National Portrait Gallery; National Library of Wales; National Library of Scotland; Leeds University (Brotherton Collection); University of Wales, Cardiff; Henry Moore Institute, Leeds; Laing Art Gallery, Newcastle upon Tyne; Liverpool Public Library; Glasgow City Library; Westminster Library and Chelsea Library; Cardiff City Library; Pembrokeshire County Library; Neath Town Library; Kent County Library; Northampton County Library; Lambeth Palace and Fulham Palace Libraries; Public Records Office, London; Public Records Office, Trowbridge, Wiltshire; Imperial War Museum; Royal Military Academy, Sandhurst; Royal Welch Fusiliers, Caernarfon and Wrexham; Beaulieu Motor Museum; Marlborough College; Eton College; Christ’s College, Brecon; St Mary Abbots Church, Kensington; Napier Institute of Technology, Edinburgh; New Beacon School, Kent; Local History Societies at Brenchley and Matfield, Kent, and at Warminster; Convent of the Assumption, Kensington Square, London, and Hengrave Hall, Suffolk.

This biography would not have been possible without the experience and support of Metro Publishing and its staff. Paul Singer – my indomitable researcher, Margaret Body – my guide through the wilderness of syntax, punctuation and spelling, Richard Cohen – my publisher and editor and Christopher Sinclair-Stevenson – my agent, have been unfailing in their patience.

My family has asked me not to thank them!
