Medieval Naval Warfare 1000-1500 [PDF ebook] 

How were medieval navies organised, and how did powerful rulers use them? Medieval Naval Warfare, 1000-1500 provides a wealth of information about the strategy and tactics of these early fleets and the extent to which the possibilities of sea power were understood and exploited. This fascinating account brings vividly to life the dangers and difficulties of medieval seafaring. In particular, it reveals the exploits of the Italian city states, England and France and examines:* why fighting occurred at sea* how battles were fought* the logistical back up needed to maintain a fleet* naval battles from the Mediterranean to the North Sea.
