Published in April 1918, the month that the Royal Flying Corps became the Royal Air Force, this little official booklet issued by the General Staff is a general introduction for pilots of the aims of aerial combat. With sections on such topics as the necessity of offensive action; attacking ground targets with bombs and machine-guns; the importance of surprise and manouevre; the evolution of formation flying; and aerial weapons this gives a clear view of how aerial fighting had evolved in the course of the Great War at the very hour of the RAF's birth.
