"I must ask of thee one promise in return, dear maid. It is this: If I win the fight in thy cause, and thou become my bride, never, as thou dost love me, must thou ask whence I came. I must never be asked by thee my name or race. This one promise alone must I crave of thee." He waited hopefully for her answer. His appearance was so noble that none could doubt him, and she answered instantly: "There is no doubt of thee in my heart, dear defender. I will never question thee. I will ever cherish thy command." He raised her to her feet, and embraced her. "I shall guard and love thee always," Lohengrin answered, and led her to the King who gave her into his charge. After that he stepped into the midst of the crowd of nobles. "I want you all to know that this maid is innocent. The tales of Frederick of Telramund are false, and now I shall prove it by vanquishing him in the fight. Great King, command us to begin." The company drew back to their places, and the King commanded six knights to measure a certain space upon each side, which he declared was a fenced field for the combat. Three Saxon nobles advanced for Lohengrin and three Brabantians for Frederick. When they had formed a circle, all stuck their spears into the ground and waited. The Herald declared that any one who interfered should lose his head. He also declared that neither combatant should use magic arts in fighting. The King stepped into the circle made for the fighters, and prayed to Heaven to let the right conquer; to give the champion of the right a stronger arm and more skill than his enemy. The six men forming the circle stood beside their spears which were stuck into the ground; the other nobles and freemen formed a larger circle outside the battle ground, while Elsa and her ladies stood in front, beneath the oak tree beside the King, and the fighters prepared to enter the circle. The King struck his sword three times upon his great shield which hung upon the tree, as a signal to begin. At the first stroke the fighters entered the circle; at the second stroke they raised their shields and drew their swords; at the third stroke they began the fight. After a mighty battle, Frederick fell, and Lohengrin placed the point of his sword at his throat. "I shall spare thee, Frederick of Telramund. Repent in peace," he said, standing aside that Telramund might get up from the ground. The six men drew their spears from the ground, and the others who had taken sides put their swords back into their scabbards, while Elsa rushed into the knight's arms. The King cried to Lohengrin: "Hail!" As Elsa sank upon the knight's breast, she sang of her love for him and of her faith, and all rejoiced in having her innocence proven, except Ortrud. She, indeed, looked dark and menacing.
