lieutenant for the fleet, exercising immense delegated powers in complete subjection to the Crown. But during the anarchy of the Wars of the Roses, such a man as Warwick, who garrisoned Calais with his own followers, and had the command of the ships, of which many were his own property, was practically master of the Channel, and rendered as much obedience to the king--or as little--as he pleased. While the King of England possessed dominions on the Continent, he drew part of his naval forces from them. There is occasional mention of the king's ships and galleys of Aquitaine. The great reputation of the Italian seamen of the Middle Ages led to their employment now and then, and one, Nicholas Ususmaris of Genoa, was for a time in the service of Edward III., though only to command the ships belonging to Aquitaine. The Mediterranean seamen were employed very largely by the King of France, who was driven to use them by the want of skilful men among his own subjects. In the Middle Ages the English king appears only to have had recourse to them when he wished to make use of that typical Mediterranean craft, the galley. Under Henry VIII. Italians were brought in largely to serve both as seamen and shipbuilders, but by that time a larger class of vessel and a more extensive art of seamanship had begun to prevail. The galley, as has been already said, has never been found to answer in the Channel, and its brief appearances there have been of little note. For the classes of vessels he mainly used, that is, ships which might take to the oar as a subsidiary resource, but relied chiefly on the sail, the king could find men in abundance among his own subjects.
