"What then shall we do?" asked the barons.
"I shall tell you," said Merlin. "There are two brethren beyond the sea, both kings, and marvellously valiant men. One of these is King Ban of Benwick, and the other King Bors of Gaul. These monarchs are at war with a mighty warrior, King Claudas. My counsel then is, that our king ask the aid of these monarchs in his wars, and engage in return to help them in their war with their foe."
"It is well counselled," said the king and his barons.
Accordingly two knights with letters were sent across the seas, and after various adventures reached the camp of Kings Ban and Bors. These valiant monarchs gladly responded to Arthur's request, and, leaving their castles well guarded, came with ten thousand of their best men to the aid of the youthful king. Then were held great feasts, and a noble tournament was given on All-hallowmas day, at which Sir Kay carried off the honors of the lists and received the prize of valor.
But sport had soon to give place to war, for the hostile kings, now eleven in all, with a host of fifty thousand mounted men and ten thousand footmen, were marching upon King Arthur's camp, then at the Castle of Bedegraine, in Sherwood forest.
Two nights before the hosts met in battle, one of the hostile leaders, known as the king with the hundred knights, dreamed a wondrous dream. It seemed to him that there came a mighty wind, which blew down all their castles and towns, and that then there came a great flood and carried all away. All who heard this dream said that it was a token of great battle, but by its portent none were dismayed, for they felt too secure in their strength to heed the warning of a dream.
Soon the two armies drew together, and encamped at no great distance asunder. Then, by advice of Merlin, a midnight attack was made by Arthur and his allies upon the host of the eleven kings, as they lay sleeping in their tents. But their sentinels were alert, the sound of the coming host reached their wakeful ears, and loud the cry ran through the camp:
"To arms! lords and knights, to arms! The enemy is upon us! To arms! to arms!"
On like a wave of war came the force of Arthur, Ban, and Bors. The tents were overthrown, and all the valor of the eleven kings was needed to save their army from defeat. So fiercely went the assault that by day-dawn ten thousand of their men lay dead upon the field, while Arthur's loss was but small.
