This sequel to the former Governor of Eritrea's "Cronache Etiopiche" and "Etiopia d'Oggi" is a carefully integrated chronology of the war and of the subsequent "police" operations up to April 1937. Most of the chapters concern the military operations, are illustrated by topographic maps, and clearly show the primary rôle of aviation. However, since most foreign observers emphasize the importance of gas in demoralizing the Ethiopian forces, it might have been wise for the author either to refute these charges or admit their truth. The concluding chapters explain the organization of the new Italian Empire in East Africa. This is the best and most comprehensive book on the Ethiopian adventure to appear in Italy.
