Now, all being prepared, the marshal stood forth and blew upon his trumpet, and therewith those two parties of knights rushed the one against the other, each in so great a cloud of dust that one could hardly see the knights in their passage. Therewith they met in the midst of the meadow of battle, with such a crash and uproar of splintered lances as was terrible to hear.
And for a while no man could see what was toward, so great was the dust and the tumult. But by and by the dust raised itself a little and then Sir Launcelot perceived that the party of King Bagdemagus had been pushed back by that other party, as might have been supposed in such a case.
So Sir Launcelot looked upon the battle for some while and he saw that the party of King Bagdemagus was pushed farther and farther back. Then by and by Sir Launcelot said to his knights-companion: "Messires, methinks now is our time to enter this engagement."
Therewith he and they rode forth out of that woods, and they rode down the hill and across the fields and so came into that meadow-of-battle.
Sir Launcelot and his companions enter the battle.
At that time the party of the King of North Wales was so busily engaged in its assault upon the party of King Bagdemagus that very few of those knights engaged were aware of those four knights coming, and those who were aware of them thought but very little of the coming of so small a number. So no one interfered with their coming, wherefore they were able to bear down with great speed upon the flank of the party of the King of North Wales. Therewith they struck that flank with such force that both horses and horsemen were overturned by their assault.
In that encounter Sir Launcelot carried a spear that was wonderfully strong and tough. With it he ran with great fierceness into the very thickest of the press, and before he was checked he struck down five knights with that one spear. And likewise those three knights that were with him did such good service that all that flank of the party of the King of North Wales was thrown into great confusion and wist not what to do for to guard themselves against that fierce, furious onset.
Then Sir Launcelot and his three companions bore back a little, and when they got their distance they ran again into the press, and this time Sir Launcelot overthrew the King of North Wales himself, and that with such violence that the bone of his thigh was broken, and he had to be carried away out of that field by his attendants. And in this second assault Sir Launcelot and the three knights who were with him overthrew eleven knights besides the King of North Wales, wherefore all that part of the press began to break away from them and to seek some place where they could defend themselves from such another assault.
Now when the party of King Bagdemagus saw into what confusion the other party were thrown by these four knights-champion, they began a very fierce and furious attack, and with such vehemence that in a little the party of the King of North Wales began to bear back before them. So, what with those who withdrew before Sir Launcelot's assault, and what with those who withdrew from the assault of King Bagdemagus, there was a great deal of confusion in the ranks of the party of the King of North Wales.
Sir Launcelot overthrows Sir Mordred.
