This book analyses the letters of marginalised groups of World War I soldiers - including Black, Indian and disabled ex-servicemen - from a linguistic perspective, looking at issues such as descriptions of disability, identity and migration, dealing with minority groups who have long been rendered invisible, and exploring how these writers position themselves in relation to the 'other'. The author makes use of a corpus-assisted approach to examine identity construction and performance, shedding light on a previously under-explored demographic. This book will be of interest to students and scholars of World War I history, language and identity, psychological and physical disability, as well as readers seeking a fresh angle on a key period of 20th century history.
