The period of relative peace enjoyed by the Roman Empire in its first two centuries ended with the Marcomannic Wars. The following centuries saw near-constant warfare, which brought new challenges for the Roman Navy. It was now not just patrolling the Mediterranean but also fighting against invaders with real naval skill, such as Genseric and his Vandals.

With research from newly discovered shipwrecks and archaeological finds as well as the rich contemporary source material, this study examines the equipment and tactics used by the navy and the battles they fought in this tumultuous period, which includes the fall of Rome and the resurgence of the Eastern Empire under Justinian the Great.

Using spectacular illustrations, carefully researched ship profiles, and maps, this third volume in Osprey's Roman Warships miniseries charts the ultimate evolution of the Roman fleet in one of the most fascinating periods of its history.
