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 them 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. "Now shall ye do my advice," said Merlin; "I would that King Ban and King Bors, with all their fellowship of 10,000 men, were led to ambush in this wood ere daylight, and stir not therefrom until the battle hath been long waged. And thou, Lord Arthur, at the spring of day draw forth thine army before the enemy, and dress the battle so that they may at once see all thy host, for they will be the more rash and hardy when they see you have but 20,000 men." To this the three knights and the barons heartily consented, and it was done as Merlin had devised. So on the morrow when the hosts beheld each other, the host of the north was greatly cheered to find so few led out against them. Then gave King Arthur the command to Sir Ulfius and Sir Brastias to take 3000 men-at-arms, and to open battle. They therefore setting fiercely on the enemy slew them on the right hand and the left till it was wonderful to see their slaughter.
