OUTLINE HISTORY
The two main scenes of action for medieval European naval warfare were the
Mediterranean and the North Sea/English Channel. Conflicts between fleets were
relatively few. Such as did occur were usually over transporting troops and supplies for
war, or the domination of trade routes. Much medieval naval conflict had to do with illicit
action by pirates—a plague to all sides though states often encouraged privateering. In
the Mediterranean, the focus was on islands and ports on major routes. Attempts to clear
out pirate bases, as at Rhodes, Sapienza or the Barbary Coast, were another type o
conflict. Channel warfare was mostly over trade, as when England fought Flanders over
wool and cloth, and France over wine. The wars between Venice and Genoa were about
control of trade to the Middle and Far East. Fishing grounds also caused conflict.

State fleets were rare and usually small, supplemented in war by mercantile shipping.
Ships involved in naval warfare were hardly different from those used for trade. In the
later Middle Ages naval powers built more ships as the expense of large warships became
too great for private enterprise. We do find some large fleets. In 1347 Edward III crossed
the Channel with 738 ships carrying 32,000 men to Calais.
We know about ships from three main sources: from verbal description in narrative
sources, from manuscript illustration and works of art, and, increasingly important, from
archaeology. Ships buried on land were the first to provide evidence, as at Sutton Hoo,
but underwater work offers most for the future, especially on construction methods.
Early Mediterranean ships were on the Roman model, galleys propelled partly by oars.
The Romans and others produced ships designed for war, a tradition continued by the
Byzantines. They had underwater rams to hit below water level and sink ships. This was
not a major feature in medieval warfare, where the projecting bow became higher from at
