But no time was lost in mere shooting. Two English ships crashed into the bows and the port side of the "Cristopher," and with the cry of "St. George for England!" a score of knights vied with each other for the honour of being first on board of the enemy. The other ships of the English van swung round bow to bow with the next of the French line, grappled and fought to board them. King Edward himself climbed over the bows of a French ship, risking his life as freely as the youngest of his esquires. Then for a while on the French left it was a question of which could best handle the long, heavy swords, made not for deft fencing work, but for sheer hard hacking at helmet and breastplate.

Behind this fight on the flank, ship after ship slipped into the river, but at first attacked only the left division closely, those that had pushed furthest in opening with arrow fire on the centre and leaving the right to look helplessly on. The English archers soon cleared the enemy's tops of their bowmen, and then from the English masts shot coolly into the throng on the hostile decks, their comrades at the bulwarks shooting over the heads of those engaged in the bows. The English arrows inflicted severe loss on the enemy, but the real business was done by the close attack of the boarding-parties, that cleared ship after ship from the left inwards, each ship attacked in turn having to meet the knights and men-at-arms from several of the English vessels.

But the French fought with determined courage, and hour after hour went by as the attack slowly worked its way along the line. The slaughter was terrible, for in a sea-fight, as in the storming of a city wall, no quarter was asked or given. The crews of the captured ships were cut down as they fought, or driven over the stern into the water, where, for the most part, their heavy armour drowned them.

It was past noon, and the tide was turning when the left and centre, the squadrons of Kiriet and Bahuchet, were all captured. Then the attack raged round the nearest vessels on the right, tall ships of the Genoese. Most of these, too, were taken, but as the tide ran out King Edward feared his large ships would ground in the upper waters of the estuary, and the signal was given to break off the attack, an order welcome even to the weary victors.

Barbavera, with a few ships, got clear of the beaten right wing and lay up near Sluys, while the English plundered and burned some of their prizes and took the best of them out to sea on the ebbing tide. In the night the Genoese admiral slipped out to sea, and got safely away. The French fleet had been utterly destroyed, and the Genoese sailors had no intention of further risking themselves in King Philip's quarrel. They thought only of returning as soon as might be to the Mediterranean.

King Edward went on to Ghent, after landing his fighting-men, and sending his fleet to bring further forces from England. Henceforth for many a long year he might regard the Channel as a safe highway for men and supplies for the war in France.

The victory of the English had cost them a relatively trifling loss. The French losses are said to have been nearly 30,000 men. Strange to say, among the English dead were four ladies who had embarked on the King's ship to join the Queen's Court at Ghent. How they were killed is not stated. Probably they were courageous dames whose curiosity led them to watch the fight from the tall poop of the flagship as they would have watched a tournament from the galleries of the lists, and there the cross-bow bolts of the Genoese found them.

There is an old story that men feared to tell King Philip the news of the disaster, and the Court jester broke the tidings with a casual remark that the French must be braver than the English, for they jumped into the sea by scores, while the islanders stuck to their ships. The defeat at sea prepared the way for other defeats by land, and in these campaigns there appeared a new weapon of war—rudely fashioned cannon of short range and slow, inaccurate fire—the precursors of heavier artillery that was to change the whole character of naval warfare.

It was the coming of the cannon that inaugurated the modern period. But before telling of battles in which artillery played the chief part, we must tell of a decisive battle that was a link between old and new. Lepanto—the battle that broke the Turkish power in the Mediterranean—saw, like the sea-fights of later days, artillery in action, and at the same time oar-driven galleys fighting with the tactics that had been employed at Salamis and Actium, and knights in armour storming the enemy's ships like Erik Jarl at Svold and King Edward at Sluys.
