This work reviews the development of British military ideas on armoured forces from 1903 to 1939. Great Britain was the nation which first developed the tank, first used it in action and first gained dramatic results by its employment. The British continued as world leaders in the field of mechanized warfare until the early 1930s. The author offers his interpretations of the early history of British armoured forces and explains why Britain had lost their leading position as tank users by the outbreak of World War II.
