Then Fortager began to entreat him humbly, and swore that no harm should come to him whatever he should say. And at length Merlin told him that the red dragon betokened Fortager and the power he had obtained through killing King Moyne. The white dragon with the two heads represented the true heirs, Aurilis-Brosias and Uther-Pendragon, whose kingdom he held, and as the white dragon, hunted to the valley, there regained his breath, and drove back the red dragon to the plain, so should these heirs, driven out to Brittany, find help and succour there, and were even now sailing to Britain with a vast army to hunt King Fortager through the land, and to drive him to his castle on the Plain. And there, while he was shut up, with his wife and children, he should be burnt to ashes.
Then King Fortager, when he heard this, was grieved at heart, and prayed Merlin to tell him how to avoid this terrible fate, or at least how he might escape with his life. But Merlin only answered:
"What will be, will be."
Then Fortager, in his wrath, tried to seize the boy; but Merlin vanished from his sight, and while they sought him, he was all the time far away in the cell of Blaise the hermit. And there he remained for many a year, and wrote a book concerning all the things that were going to happen in Britain.
Meantime all that he had foretold took place. For Uther-Pendragon and his brother marched to Winchester with an army, and when the citizens saw the banner of their old British kings, they drove out the Danish garrison, and opened the gates to the sons of Constaunce. And not one of the men of Britain would fight on the side of Fortager or Angys, nor would the men of their armies fight against their friends and brothers in the land. So they won an easy victory, and drove Fortager away to his fortress on Salisbury Plain, where he shut himself up with his wife and children. And the men of Britain threw wildfire on the walls, and burnt him there, and all that belonged to him, and made his castle walls level with the ground.
But Angys fled away to a fortress on a hill, whither Uther-Pendragon followed, but could not come to him because of the strong bulwarks by which it was surrounded.
Then, hearing men speak often of the wisdom of Merlin, Uther-Pendragon sent men far and wide to seek him. And one day, when these messengers sat at dinner, there came in to them an old beggar, with a snow-white beard and ragged shoes and a staff in his hand, and said: "Ye are wise messengers who seek the child Merlin! Often to-day have ye passed him on the road, and yet ye knew him not. Go back to Uther, and tell him that Merlin waits in the wood hard by; for, search as ye will, ye will never find him."
And with these words the old man disappeared. Then the messengers, wondering greatly, returned, and told all to Uther, who left his brother to maintain the siege, and went to the wood to seek Merlin. And first he met a swineherd, who said he had lately seen the elf child, and then a chapman with his pack, who said the same. Then came a countryman, who said that Merlin would surely keep his tryst, but that Uther must be patient, as he still had some work to do ere he sought the palace.
So the prince waited patiently far into the night; and at length the countryman returned to him, saying: "I am Merlin, and I will now go with you to the camp."
When they got there Aurilis-Brosias came out to meet them, and said: "Brother, there came a countryman in the night, who waked me, saying: 'Angys is come out of his fortress, and has stolen past your sentinels, and is in your camp, seeking to take your life.' So I sprang up, and, seeing Angys at the door, I rushed upon him, and slew him, my sword passing through his coat of mail as if it had been naught. But when all was over, the countryman had vanished."
