A detailed account of the naval enterprises of the Middle Ages would go altogether beyond the scale of this work. Nor is the story one which can be told without monotony. In spite of the many improvements in the construction of ships and the advance of seamanship, the means of conducting a regular naval campaign were wanting. Vessels were still unable to keep the sea during long periods of cruising and blockade. They were not strong enough to stand the strain, nor could they carry the water and provisions required for the large fighting crews crowded into vessels ranging from fifty to three hundred tons. It followed from this double disability that warfare on sea was conducted by expeditions of brief duration. A fleet was collected, and sailed to attack the enemy's ships or harry his coast. When successful, it gathered all the plunder it could find, and returned home to be laid up for repair, while its crews were disbanded. Thus it not infrequently happened that, immediately after a striking victory, a raiding expedition of the enemy was able to pounce on some part of our coast, and retaliate by murder and ravage for what he had just suffered at home. We had a prevailing superiority, due to the greater number and efficiency of English seamen, and the greater average faculty of the English kings; but we must not look for examples of coherent, orderly war conducted through months, or even years, of effort by permanent forces. A few examples must suffice to illustrate the general character of these centuries of conflict. No better instance of the nature of mediæval sea warfare can be found than the story of the desperate feud between the English and Norman fishermen, in the reign of Edward I. In 1293 a dispute arose in some port of Normandy or Gascony--for the authorities differ--between the French and English sailors. The point at issue, it is said, was which was entitled to drink first. It came rapidly from words to blows, and a man was killed. The authorities again differ as to whether he was French or English. All agree that the English sailors were chased back to their ships by a mob. Their ship put to sea, pursued by French vessels, and escaped. But the passions of the Norman seamen being now thoroughly aroused, they were minded to pursue the feud. Meeting six English merchant ships, they fell upon them and captured two. They hanged the crews at the yardarm, together with some dogs by way of greater insult. Then they paraded the Channel, plundering all they met, making "no distinction between an Englishman and a dog." In the meantime, the four ships which had escaped took refuge in the Cinque Ports. Here they promptly found allies, and a foray was rapidly arranged to revenge the outrage. A squadron of English ships, mainly drawn from the Cinque Ports, started in pursuit of the French. Finding that the enemy had returned to port, the English adventurers entered the Seine, captured six vessels after
