This publication includes a series of lectures given at the RAF Staff College in  the years 1922 - 1926. There are a number of topics dealt with including “Fighting in the Air,” “Air Home Defence,” “War Experiences,” “Anti-Submarine Patrolling by Aircraft,” “The Royal Air Force in Iraq since 1918,” “Morale,” “Air operations on the N.W. Frontier,” and even “A study of Marlborough and Napoleon.” Of great interest in that the war experiences are important in getting a better picture of World War I in the air, but the lectures also show what were matters of concern from a policy and doctrine point of view in the mid-1920s.
