Originally published in 1938, this book was the first to be written which dealt with the history of Army Development during the confused years which followed the South African War. The period 1899–1914 marked the change from Victorian scarlet and pipeclay to the service dress of the Expeditionary Force of 1914. Similarly, it saw the growth of the Volunteer Rifle Corps of the nineteenth century into the Territorial Force of the Haldane Scheme. The writer, sometime history scholar of St John’s College Cambridge, himself a Territorial of twenty-three years’ service, was at the time one of the T.A. officers recently appointed to newly created posts at the War Office.
