Roman Naval Warfare

Military supremacy of the seas could be a crucial factor in the success of any land campaign, and the Romans well knew that a powerful naval fleet could supply troops and equipment to where they were most needed in as short a time as possible. Naval vessels could also supply beleaguered ports under enemy attack and, in turn, blockade ports under enemy control. A powerful navy was also indispensable to deal with pirates, who wreaked havoc with commercial sea-traders and even, on occasion, blockaded ports. Naval warfare had its own unique dangers, though, with adverse weather being the biggest threat to success, which is why naval campaigns were largely limited to between April and November.
