The king looked sternly at the young man, and there was silence among them all as men waited for Arthur's reply.

Then it happened that a young chieftain, standing near the king, felt something bite his foot where the low leathern shoe left it naked. He looked down and saw that he was treading on a viper, which had struck him and was about to strike again. With a cry the knight stepped aside, drew his sword, and cut the reptile in two.

As the blade flashed, silvery bright in the sunlight, a great hoarse cry rose like thunder from the two masses of men watching them on either side; trumpets blared and horns squealed, and shouts of command rose sharp and keen.

Instantly the men standing with Arthur and Mordred looked about them, saw where the young chieftain stood with drawn sword, and knew that now nothing could avert the battle.

'The gods will have it so!' sneered Mordred.

Already the earth trembled and shook with the beat of ten thousand feet of the armies rushing together. A knight of Mordred's, drawing his sword, thrust it into the breast of one of Arthur's chieftains, with the cry:

'This for thy land, Sir Digon, that marches with mine!'

Instantly others fell to fighting hand-to-hand, striking on targe and helm; but Sir Owen, Sir Kay and Sir Bedevere surrounded the king, and all hurried back to the army approaching them. So likewise did Sir Mordred.

Then came the crash of battle, as line on line, with flashing swords held high, the ranks of war closed. Blades rose again, stained red, fierce strangled cries came from men in the death-grips, helms were cracked, shields riven, dirks sank home, and men who once had drunk and jested with laughing looks over the same mead-board, now met fierce eye to eye, and never parted until one or both fell in the swaths of the death-harvest.

All day the stubborn battle raged, and ever the king sought out the rebel Mordred, but never reached him. Many valiant deeds he did, wielding his sword Excalibur; and by his side were Owen and Kay, Lucan and Bedevere. So spent were they at the last that hardly could they lift their swords, and so sick of the slaying were they that gladly would they have ceased. But ever some vicious band of Mordred's knights would come upon them, and then they quitted them like men, and ceased not till their enemies had fled or were slain.
