She told the Prince the story you already know: how her dear parents were imprisoned by a huge dragon, and how the Red-cross Knight, who was to have rescued them, had been betrayed into the hands of a cruel giant, in whose dungeons he lay, disarmed and helpless.
Before she had quite ended her tale, the poor damsel grew faint from grief and dread, but the Prince comforted her with cheering words.
"Truly," he said, "you have great cause of sorrow; but take comfort and courage, for until I have rescued your captive knight be assured that I will not leave you."
So the whole party went on together, until they reached a great castle. Here, said the dwarf, lay his luckless lord, and here the Prince must try his prowess. Whereupon the Prince alighted from his steed, and bidding Una remain where she was and watch the issue of the fight, took Timias, his squire, and strode up to the castle wall. He found the gates fast closed, and no one to keep guard or answer to his call. At this, the squire blew a small bugle, which hung by his side, adorned with twisted gold and gay tassels, and writ all over with the wonders of its virtue.
None ever heard its shrill call who did not tremble before it. There was no gate however strong, or lock however firm, that did not burst open at its summons. And now, as the squire blew the magic horn, the grim castle quaked, every door flew open, and the giant himself rushed forth with an angry stare on his cruel countenance, eager to learn who or what this might be that had dared his dreaded power. After him appeared Duessa, riding a many-headed monster, with a fiery, flaming tongue in every one of its many heads.
At once the Prince began a furious attack on the monster. Thereupon the giant buckled to the fight, and lifting up his dreadful club, all armed with ragged knobs and gnarled knots, thought to have slain the Prince at a single blow. But he, wise and wary, leapt swiftly aside, and the great weapon fell so heavily, that it sank three yards deep into the ground, making the earth tremble. Now, Orgoglio could not easily uplift his club, and as he strove to drag it from the deep cleft, the Prince smote off his left arm, which fell to the ground, a senseless block, while streams of blood gushed from the wound. Dismayed by the pain, Orgoglio roared aloud, and Duessa hastened to draw up her many-headed charger to his aid. But the squire soon forced the horrid beast to retreat, and at this Duessa in her pride rebelled and urged the monster afresh; but in vain, for Timias dealt mighty strokes, and stood firmly to his post.
Then Duessa resorted to her witch ways, and taking out a golden cup, murmured enchantments over it, and sprinkled some of its contents upon Timias. His courage immediately faded away, and his senses became dull and numb, and he fell helpless before the monster.
The dreadful beast laid its claws upon Timias' neck, and kept him pinned to the ground, until his life was nearly crushed out: then it left him with neither power nor will to rise.
But when Prince Arthur beheld the sad plight into which his well-loved squire had fallen, he left off fighting with Orgoglio, and turned upon the beast, and struck off one of its monster heads.
Thereupon Orgoglio went to Duessa's aid, and putting all his force into his remaining arm, he let drive his oaken club with such terrible fury, that falling on the Prince's shield, it bore him to the ground.
