The Roman Empire was not only built by the strength of the legions but also by a navy that was the most powerful maritime force ever to have existed. It was the presence of this fleet that secured the trade routes and maintained the communications within the huge Empire. The superior design of their warships, coupled with skilled naval commanders such as Agrippa, Sextus Pompeius and Pontus Euxinus, gave the Roman Empire a formidable navy that could defend the coasts of the three continents under the rule of the Caesars.
   Featuring archaeological photography and lavish artistic reconstructions, this book reveals the design and development history of Rome's naval force at the height of its Imperial power. As well as examining its warships, it reveals the navy's structure and the tactics that were developed to make the most of Rome's naval design superiority.
