“She is a sister to the Lady of the Lake, but she is evil,” returned Merlin, sadly. “But right glad am I to see thee again, my lady fairy. Wilt thou not give me help in this danger?”

“I had come hoping for some quiet talk with thee, Merlin, but it is not to be,” said the fairy. “What with this danger and thy weakness. Yet help cometh.”

“It is sore needed,” returned the wizard. “See, even now, my magic avails little.”

Rose and Ruth, looking eagerly between the protecting walls, saw that the ring of red champions was weakening. One by one they began to give way, though still fighting desperately.

“Lordy!” exclaimed Rose, breathlessly, “just look at the fearful whacks that big black Knight is giving to the little red one—there, he nearly got him down that time. Can’t we do something? It seems awful to stand here and watch our soldiers getting the worst of it.”

At this moment there was a great shout from all the black knights, and with the roar of that shout the red knights dropped their weapons, or fell from their horses, or stumbled, if they were afoot, and fell to the ground. It seemed indeed as though some bad magic were at work.

Merlin groaned, and Guinevere began to sob. Ruth looked frantically round for the fairy, forgetting she could not be seen.

“Fairy, can’t something be done?” she cried.

“We’re doing all we can,” returned the voice of the fairy, and it seemed to be a sort of gasp, as though she were indeed straining every power she had.

At this moment a number of damsels ran from the forest and gave each of the red knights something to drink from a shining goblet. At once these fell to with renewed strength, laying on so lustily with their swords that the black warriors were now forced back.
