These words said, Arthur sallied from the tower at the head of all his knights, and fell fiercely on the besiegers in their camp. All went down before his bold assault, the hosts of the hostile kings retreating in dismay. Great deeds were done that day, Sir Kay and other knights slaying all before them, while Arthur laid on nobly, and did such marvellous feats of arms that all who saw him wondered greatly, for until now he had been an untried youth. While the combat thus went on in Arthur's favor in front, King Lot and others of the kings made a detour and set fiercely upon his force from the rear, causing momentary dismay in his ranks. But Arthur wheeled alertly with his knights, and smote vigorously to right and left, keeping always in the foremost press, till his horse was slain beneath him, and he hurled to the ground.
King Lot took instant advantage of this, and with a mighty blow prostrated the unhorsed king. But his knights hastily surrounded him, drove back his crowding foes, and set him on horseback again. And now King Arthur drew the magic sword, and as he waved it in the air there flashed from it a gleaming lustre that blinded the eyes of his enemies. Back they went before him, many of them falling under his mighty blows, while his valiant knights followed hotly in the track of the flaming sword, and the enemy fled in panic fear.
Then the people of Carlion, seeing the enemy in retreat, came out with clubs and staves, and fell upon the defeated host, killing numbers of the dismounted knights; while the hostile kings, with such of their followers as remained alive, fled in all haste from the disastrous field, leaving the victory to Arthur and his knights.
Thus ended in victory the first battle of Arthur's famous reign. It was but the prelude to a greater one, the mighty deeds of which the chroniclers tell at great length, but of which we shall give but brief record. It was predicted by Merlin, who told the king that he should have to fight far more strongly for his crown, that the defeated kings would get others to join them, and would ere long proceed against him with a mighty force.
"I warn you," he said to the king and his council, "that your enemies are very strong, for they have entered into alliance with four other kings and a mighty duke, and unless our king obtain powerful allies he shall be overcome and slain."
