In December 1943, Lieutenant-General A.G.L. McNaughton resigned from command of the 1st Canadian Army amidst criticism of his poor generalship and of his abrasive personality. Despite McNaughton's importance to the Canadian Army during the first four years of the Second World War, little has been written about the man himself or the circumstances of his resignation. In The Politics of Command, the first full-length study of the subject since 1969, John Nelson Rickard analyses McNaughton's performance during Exercise SPARTAN in March 1943 and assesses his relationships with key figures such as Sir Alan F. Brooke, Bernard Paget, and Harry Crerar. This detailed re-examination of McNaughton's command argues that the long-accepted reasons for his relief of duty require extensive modification. Based on a wide range of sources, The Politics of Command will redefine how military historians and all Canadians look at not only "Andy" McNaughton but also the Canadian Army itself.
