_The Military History of Late Rome 425-457_ analyses in great detail how the Romans coped with the challenge posed by masses of Huns in a situation in which the Germanic tribes had gained a permanent foothold in the territories of West Rome. This analysis reassesses the strategy and tactics of the period . The book shows how cooperation between the West Roman Master of Soldiers, Aetius, and East Roman Emperor Marcian saved Western civilization from the barbarian nightmare posed by the Huns of Attila. A fresh appraisal of the great clash at the Catalaunian Fields in 451 offers new insights into the mechanics of the fighting and shows that it was a true battle of nations which decided nothing less than the fate of human civilization. Had Aetius and his allies lost the battle and had Marcian not cooperated with Aetius in 451 and 452, we would not have seen the rise of the West and the rise of the scientific thinking.
