A history and military analysis of the world-changing events following the fall of the Western Roman Empire. The Military History of Late Rome 457-518 provides a fresh new look into the events that led to the collapse of West Rome, while East Rome not only survived but went on to prosper despite a series of major defeats that included, most notably, the catastrophic campaign against the Vandals in 468. The author explains what mistakes the West Romans made and what the East Romans did right to survive. He analyzes the role of the barbarian generals and military forces in this and also offers an analysis of the tactical developments during this pivotal period as a result of which the cavalry, so famous from the accounts of Procopius, became the dominant arm in the East. The book also offers a detailed study of a number of battles that have never before been subjected to such scrutiny, and puts these firmly into the context of their times. At the very end of this period in 518, East Rome was poised to start its reconquest under Anastasius' successors Justin I and Justinian I. This book explains why this was possible.
