Major General Sir Wilkinson Dent Bird (1869–1943) saw active service in campaigns from the Niger Campaign in 1897 to the opening of the First World War, when he served in France. In 1923 he was appointed head of a committee to analyse wartime experiences and propose changes intended to modernise the British army. First published in 1920 and issued in an enlarged second edition in 1925, this book provides a comprehensive study of military strategy current at the time of publication, using historical examples to illustrate key concepts. Bird focuses primarily on land battles, with a chapter for naval battles and a small section for aerial combat. Originally intended as a guide to current strategic thinking, his book provides valuable analyses of historical battles with insights into the development of British military strategy after the First World War. This reissue is of the 1925 edition.
