That delay was used well by King Arthur, for he made great haste to pass through the wild country, filled with wide marshes and thick woods as it was, which separated him from his enemy. Then Mordred, hearing through the spies of the king's approach, got his host away and thought to pass into the lands of Devon, which were those of King Dewer, son of the dead Geraint, and held firmly for Arthur.
But in the wild waste-land beside the Endless Waters, King Arthur caught up with him, and barred his further way. And the king remembered that this was that same land, full of gaunt standing-stones and haunted by trolls and witches, where Merlin had once led him, and where he had gained the sword Excalibur.
It was late in the day when the two armies faced each other, and both prepared to pass the night upon the field. Bitter was the wind that evening, and the skies were dun and leaden of hue, as if spring had been overcome by winter; and to shelter the king a tent had been put up in a little dark wood of stunted firs, called the Wood of Drood. Just in the deep dark before the dawn, when the blood in men's veins was coldest, and the life in their hearts was weakest, a dreadful cry wailed out through the dark wood, and there came the sound as of leathery wings flapping heavily to and fro above where the king lay sleeping. Men started up about their ashen fires, their faces blanching at the terror that cried in the dark, and they heard the wailing twice repeated, while none dared try to see the thing that wailed.
Then, while their blood chilled and their breath stayed, they heard the heavy flapping pass over their heads and die away towards the camp of Mordred; and there in the distance did the three cries sound again.
Men's hearts sickened as they turned and crept the nearer to each other, but few dared to utter the words upon their lips.
Two knights slept in the tent with king, Sir Kay and Sir Owen; and they lay in the dark, trembling at the cries of terrible import. When they passed, the knights would not move, fearing to be the first to speak.
'My Lords,' came the quiet voice of King Arthur out of the dark, 'that was the voice of the Hag of Warning. Men say it hath foretold the deaths of many of my house, but I know not. Yet will I take the issue as God shall give it me, trusting in His mercy and the blood of His Son Jesus, and Him crucified.'
'Amen,' said the two knights, and said no more.
When, in a little while, the sun rose, flashing his warm rays into the fearful eyes that greeted him, men's terror quickly vanished; and when fires were lit and oaten cakes were browning on the irons, or collops sputtered on their skewers, tongues were loosened and faces began to smile. But few spoke of the cries which they had heard, for all loved their king, and hoped that somehow they had dreamed an evil dream, or had but heard the cries of some foul night-bird.
Breakfast being ended, the captains and knights began to trim their men in army array, and talk was eager of the coming battle. Then were seen, coming from Sir Mordred's camp, two bishops; and these were taken at their desire to Arthur, where he stood surrounded by his knights and chieftains.
