In this volume, Correlli Barnett explains the decay of British power between 1918 and 1940 and its final collapse between 1940 and 1945. Some have sought to expalin this ineptitude, particularly between the two world wars, by citing the tremendous costs of the First World War in both treasure and manpower. Not so, says Corelli Barnett, who ruthlessly identifies the root causes which reduced Britain eventually to a satellite of the USA. Ranging over 100 years, drawing together arguments from many spheres - education and industry, diplomatic and imperial history, Cabinet papers and the Press - it is as fascinating to read as it is significant.
