Edward had collected on the coast of Sussex a fleet intended to oppose them, and had summoned all the military forces of the south of England to accompany him; and as soon as he heard that the Spaniards were about to put to sea he set out for Winchelsea, where the fleet was collected. The queen accompanied him to the sea-coast, and the Black Prince, now in his twentieth year, was appointed to command one of the largest of the English vessels. The fleet put to sea when they heard that the Spaniards had started, and the hostile fleets were soon in sight of each other. The number of fighting men on board the Spanish ships was ten times those of the English, and their vessels were of vastly superior size and strength. They had, moreover, caused their ships to be fitted at Sluys with large wooden towers, which furnished a commanding position to their crossbow-men. The wind was direct in their favour, and they could have easily avoided the contest, but, confiding in their enormously superior force, they sailed boldly forward to the attack. The king himself led the English line, and directing his vessel towards a large Spanish ship, endeavoured to run her down. The shock was tremendous, but the enemy's vessel was stronger as well as larger than that of the king; and as the two ships recoiled from each other it was found that the water was rushing into the English vessel, and that she was rapidly sinking. The Spanish passed on in the confusion, but the king ordered his ship to be instantly laid alongside another which was following her, and to be firmly lashed to her. Then with his knights he sprang on board the Spaniard, and after a short but desperate fight cut down or drove the crew overboard. The royal standard was hoisted on the prize, the sinking English vessel was cast adrift, and the king sailed on to attack another adversary. The battle now raged on all sides. The English strove to grapple with and board the enemy, while the Spaniards poured upon them a shower of bolts and quarrels from their cross-bows, hurled immense masses of stone from their military engines, and, as they drew alongside, cast into them heavy bars of iron, which pierced holes in the bottom of the ship. Walter was on board the ship commanded by the Black Prince. This had been steered towards one of the largest and most important of the Spanish vessels. As they approached, the engines poured their missiles into them. Several great holes were torn in the sides of the ship, which was already sinking as she came alongside her foe. “We must do our best, Sir Walter,” the prince exclaimed, “for if we do not capture her speedily our ship will assuredly sink beneath our feet.”
