Full of despair at the thought that Leonora might even now be lost to him for ever, Manrico ordered his fleetest horse to be saddled at once; and, heedless of the pleading of Azucena, who feared for his scarcely-healed wounds, he rode off in hot haste for Castellor, praying that he might yet arrive in time to prevent his beloved one from taking the vows of a nun.

Now, the Count de Luna had also been told that Leonora meant to enter a convent; and as his desire to possess her was still as strong as ever, he laid a cunning plan for carrying her off, even from the threshold of the altar itself.

On the evening upon which Leonora was to take the vows, he secured a small body of soldiers to help him, and hid amidst the bushes beside the little chapel that adjoined the convent; and just as the procession of nuns approached, with the beautiful maiden in their midst, he rushed forth to stop their passage.

Leonora trembled at the sudden appearance of the Count, whom she had always disliked and feared; and when he declared passionately that he meant to carry her off by force to be his bride, she shrieked, and repulsed him indignantly.

At this critical moment, Manrico suddenly rode up, and, springing from his horse, rushed between the pair, who stared at him with utter astonishment. But surprise was quickly changed to joy and relief on the part of Leonora, who clung to her restored lover with trusting arms; and when the Count realised that the hated rival, whom he had left for dead upon the field of battle, was still alive, he was filled with disappointment and jealous despair.

Wildly, he ordered his men to attack the newcomer; but at the same time, a large troop of the enemy's soldiers, led by the officer, Ruiz, rode up to the help of Manrico. Seeing that further resistance was useless, the Count was compelled to retire; and since Leonora had no longer any desire to take convent vows, now that her lover was restored to her, Manrico joyfully led her away to the fortress of Castellor which he had been bidden to defend.

Here, for a short time, the lovers were very happy; and, hand locked in hand, they walked daily upon the battlements of the castle, talking of the sweet time to come when they would be free to live together in peace and joy.

But heart-rending grief was yet in store for them; for the Count de Luna, as leader of the storming party, was determined that the attack on the castle should meet with success, and that Manrico should be utterly defeated. With this object, he sent for additional men, and arranged all his plans with great care; and as he stood within the encampment just before the attack, he knew that Castellor was doomed. Yet he felt little satisfaction in this thought, for he could not get away from the taunting fact that even when he had parted the lovers for ever, Leonora would never care for him, since her whole heart was given to Manrico.

These galling thoughts were quickly interrupted by the sounds of a disturbance in the camp; and a few moments later, the Count's old follower, Ferrando, entered the tent, saying that a gipsy-woman had been found hovering in the neighbourhood, and seized as a spy. A number of soldiers immediately afterwards entered, dragging with them the Zingara, Azucena, who had followed her adopted son to Castellor in the hope of being able to serve him, but had now fallen into the hands of his enemies.

On questioning the gipsy and learning that she came from the mountains of Biscaglia, the Count at once demanded whether she remembered how the young child of the Count de Luna had been stolen away and carried thither; and when the Zingara replied that she had heard the story, he eagerly asked if she had any tidings of the lost one, who was his own brother.
