The growth of what came afterwards to be called flag rank may easily be traced. At first the king appointed some knight or noble to command his sea forces, and the soldiers in his ships, for some definite service. Then we hear of officers commanding in a given district for a specified time. These were first known as "captains and governors," justices or constables. In the early years of the fourteenth century the title of "Admiral" began to come into use. Captain and Admiral is the rank of the officer who commands the North and the Western Fleets. The first included the coast and sea from Dover to Berwick; the second, from Dover to the duchy of Cornwall inclusive. There was occasionally a third officer, who commanded in the Isle of Man and the Irish Sea. Of him we hear little. His chief duty was to assist in the work of subduing the Scots, and he was once at least chosen from among those chiefs of the Isles and the Western Highlands who were the worst enemies of the King of the Scots in the Lowlands. These captains and admirals were at first simple knights. Some of them were seamen of the Cinque Ports. The Alards, a family of Winchelsea, produced more than one holder of the post. The first admiral for all the seas was Sir John Beauchamp, K.G.; he was appointed by Edward III. in 1360, for a year. But it was not till later that it became the rule to have one admiral superior to all the others. In the fourteenth century a considerable change began to appear in the character, though not in formal rank or power, of these officers. In 1345 it was found necessary to appoint the Earl of Arundel to command the Western Fleet, "for no one can chastise or rule them unless he be a great man," to quote the candid confession of the King's Council. The royal authority, in fact, was growing weaker. It fell to its lowest depths in the later times of the Lancastrian line. The inevitable consequence was, that the barons seized upon the command of the ships, and used them for their own purposes. Warwick the king-maker, who among his many other offices held that of Captain of Calais and Admiral, was practically master of the whole naval forces of the country. The office of Lord High Admiral, which dates from the Lancastrian dynasty, was, in fact, a result of the aggression of the baronage. The king's authority being no longer sure of obedience, it was necessary to call in the power of the nobles, with the inevitable result. Those who knew that they were indispensable made their own terms. By the end of the Middle Ages the office of Lord High Admiral had become permanent. The old captains and admirals of the Northern and Western Fleets had disappeared, or were represented by subordinate officials, who received their commission from the Lord High Admiral. When the great Royalist reaction of the later fifteenth century had restored the authority of the Crown, the office survived. On the military side of his office the Lord High Admiral was the king's
