In Cavalry of the Clouds John Sweetman describes the development of British air power during the First World War on the Western Front, which culminated in the creation of the first independent air force, the RAF. By making use of the correspondence of airmen and ground staff of all nationalities, he illustrates the impact this new type of conflict had on those involved and their families at home. Extensively researched, Cavalry of the Clouds is an essential reference work for any student of military history.
