This introduction presents an overview of the key concepts discussed in the subsequent chapters of this book. The book focuses on the wartime renegotiations of gender. It explores the everyday lives of a group of British women volunteers named the First Aid Nursing Yeomanry (FANY) who found themselves 'straight out of Edwardian drawing rooms into the manifold horrors of the First World War'. The book historicizes the FANY Corps' beginnings in social and cultural changes at the turn of the century that encouraged women's patriotic call to service amidst a growing nationalist and militarist discourse. It analyses the service and adventures of Grace Ashley-Smith, who worked as a FANY in Belgium in the autumn of 1914. The book examines the first collective FANY war service in Calais and their work with the Belgians at the Lamarck Hospital during late 1914 through 1915.
