Then King Lot, King Carados, and the King of the Hundred Knights--who also rode with them--going round to the rear, set on King Arthur fiercely from behind; but Arthur, turning to his knights, fought ever in the foremost press until his horse was slain beneath him. At that, King Lot rode furiously at him, and smote him down; but rising straightway, and being set again on horseback, he drew his sword Excalibur that he had gained by Merlin from the lady of the lake, which, shining brightly as the light of thirty torches, dazzled the eyes of his enemies. And therewith falling on them afresh with all his knights, he drove them back and slew them in great numbers, and Merlin by his arts scattered among them fire and pitchy smoke, so that they broke and fled. Then all the common people of Caerleon, seeing them give way, rose up with one accord, and rushed at them with clubs and staves, and chased them far and wide, and slew many great knights and lords, and the remainder of them fled and were seen no more. Thus won King Arthur his first battle and put his enemies to shame. But the six kings, though sorely routed, prepared for a new war, and joining to themselves five others swore together that, whether for weal or woe, they would keep steadfast alliance till they had destroyed King Arthur. Then, with a host of 50,000 men-at-arms on horseback, and 10,000 foot, they were soon ready, and sent forth their fore-riders, and drew from the northern country towards King Arthur, to the castle of Bedgraine. But he by Merlin's counsel had sent over sea to King Ban of Benwick and King Bors of Gaul, praying them to come and help him in his wars, and promising to help in return against King Claudas, their foe. To which those kings made answer that they would joyfully fulfil his wish, and shortly after came to London with 300 knights, well arrayed for both peace and war, leaving behind them a great army on the other side of the sea till they had consulted with King Arthur and his ministers how they might best dispose of it. And Merlin being asked for his advice and help, agreed to go himself and fetch it over sea to England, which in one night he did; and brought with him 10,000 horsemen and led them northward privately to the forest of Bedgraine, and there lodged them in a valley secretly. Then, by the counsel of Merlin, when they knew which way the eleven kings would ride and sleep, King Arthur with Kings Ban and Bors made themselves ready with their army for the fight, having yet but 30,000 men, counting the 10,000 who had come from Gaul.
