Then Tristan was glad, and henceforward from that day no one dared enter the wild wood, for terror guarded it and the lovers were lords of it all: and then it was that Tristan fashioned his bow "Failnaught" which struck home always, man or beast, whatever it aimed at.
My lords, upon a summer day, when mowing is, a little after Whitsuntide, as the birds sang dawn Tristan left his hut and girt his sword on him, and took his bow "Failnaught" and went off to hunt in the wood; but before evening, great evil was to fall on him, for no lovers ever loved so much or paid their love so dear.
When Tristan came back, broken by the heat, the Queen said "Friend, where have you been?"
"Hunting a hart," he said, "that wearied me. I would lie down and sleep."
So she lay down, and he, and between them Tristan put his naked sword, and on the Queen's finger was that ring of gold with emeralds set therein, which Mark had given her on her bridal day; but her hand was so wasted that the ring hardly held. And no wind blew, and no leaves stirred, but through a crevice in the branches a sunbeam fell upon the face of Iseult and it shone white like ice. Now a woodman found in the wood a place where the leaves were crushed, where the lovers had halted and slept, and he followed their track and found the hut, and saw them sleeping and fled off, fearing the terrible awakening of that lord. He fled to Tintagel, and going up the stairs of the palace, found the King as he held his pleas in hall amid the vassals assembled.
"Friend," said the King, "what came you hither to seek in haste and breathless, like a huntsman that has followed the dogs afoot? Have you some wrong to right, or has any man driven you?"
But the woodman took him aside and said low down: "I have seen the Queen and Tristan, and I feared and fled."
"Where saw you them?"
"In a hut in Morois, they slept side by side. Come swiftly and take your vengeance."
"Go," said the King, "and await me at the forest edge where the red cross stands, and tell no man what you have seen. You shall have gold and silver at your will."
The King had saddled his horse and girt his sword and left the city alone, and as he rode alone he minded him of the night when he had seen Tristan under the great pine-tree, and Iseult with her clear face, and he thought: "If I find them I will avenge this awful wrong."
