Brian Holden Reid now considers afresh the military thought of Major-General J.F.C.Fuller - a pioneer of tank warfare and one of the most important military thinkers of the twentieth century. With a wealth of documentation, much of it previously untapped, Dr Reid explores Fuller's formative experiences, showing how his early life, his service in the Boer War and in India, and his friendships with many alienated intellectuals, including the notorious Aleister Crowley, combined to shape his mental outlook and, eventually, his study of the phenomenon of war.
