"I warn you that your enemies are very strong. They have added to their numbers so that now you have against you eleven mighty kings." At this the lords looked dismayed. "Unless our lord Arthur has more men than he can find in his own realm," said Merlin, "he will be overcome and slain. Therefore I give you this counsel. There are two brothers across the sea; both are monarchs and both very strong. One is King Ban of Benwick, and the other is King Bors of Gaul. Now these two have an enemy, also a powerful ruler. Therefore, send to the brothers, King Bors and King Ban who are now both in Benwick, and say to them that if they will help Arthur in his war against the eleven kings, Arthur will help them against their common enemy." "That is very good counsel," said the king and the lords. So they chose Sir Ulfius and Sir Brastias as messengers, and these two hurried away, hopeful of success. When they reached the town in Benwick where King Bors and King Ban were, knights came forth to receive them and to hear their message. As soon as it was learned from whom they had come they were led into the presence of the brothers. Both were very large men. King Bors was dark, and was dressed in black armor. King Ban was dark, too; the colors that he wore on his shield were green and gold. He was the father of Sir Lancelot, the knight who afterwards became the most powerful of the followers of Arthur. The two kings received Sir Ulfius and Sir Brastias with much favor. "Tell King Arthur," they said, "that we will come to him as quickly as we can." Then they gave splendid gifts to Sir Ulfius and Sir Brastias, who hurried back to Arthur with the message. In a short time King Bors and King Ban arrived with ten thousand of their soldiers, and as Arthur had ten thousand, they felt certain of victory. They went into Wales, a country which Arthur's followers knew well, and waited confidently for the enemy. The eleven kings collected a great host of sixty thousand men, fifty thousand on horseback and ten thousand on foot. They marched towards the place where Arthur was, and set up their camp near a wood about a mile distant. When Merlin knew this, he said to Arthur and the two kings: [Illustration: _King Bors and King Ban_] "This is my advice: Set upon your enemies at midnight when they are unprepared, and then you will have the advantage."
