It was with difficulty that Carthoris restrained the impulse to rush forward to the side of the Ptarthian princess; but in the end his better judgment prevailed, for in the face of such odds he knew that he should have been but throwing away, uselessly, any future opportunity he might have to succour her. He saw her dragged to the foot of the rostrum. He saw Hortan Gur address her. He could not hear the creature’s words, nor Thuvia’s reply; but it must have angered the green monster, for Carthoris saw him leap toward the prisoner, striking her a cruel blow across the face with his metal-banded arm. Then the son of John Carter, Jeddak of Jeddaks, Warlord of Barsoom, went mad. The old, blood-red haze through which his sire had glared at countless foes, floated before his eyes. His half-Earthly muscles, responding quickly to his will, sent him in enormous leaps and bounds toward the green monster that had struck the woman he loved. The Torquasians were not looking in the direction of the forest. All eyes had been upon the figures of the girl and their jeddak, and loud was the hideous laughter that rang out in appreciation of the wit of the green emperor’s reply to his prisoner’s appeal for liberty. Carthoris had covered about half the distance between the forest and the green warriors, when a new factor succeeded in still further directing the attention of the latter from him. Upon a high tower within the beleaguered city a man appeared. From his upturned mouth there issued a series of frightful shrieks; uncanny shrieks that swept, shrill and terrifying, across the city’s walls, over the heads of the besiegers, and out across the forest to the uttermost confines of the valley. Once, twice, thrice the fearsome sound smote upon the ears of the listening green men and then far, far off across the broad woods came sharp and clear from the distance an answering shriek. It was but the first. From every point rose similar savage cries, until the world seemed to tremble to their reverberations. The green warriors looked nervously this way and that. They knew not fear, as Earth men may know it; but in the face of the unusual their wonted self-assurance deserted them. And then the great gate in the city wall opposite the platform of Hortan Gur swung suddenly wide. From it issued as strange a sight as Carthoris ever had witnessed, though at the moment he had time to cast but a single fleeting glance at the tall bowmen emerging through the portal behind their long, oval shields; to note their flowing auburn hair; and to realize that the growling things at their side were fierce Barsoomian lions. Then he was in the midst of the astonished Torquasians. With drawn long-sword he was among them, and to Thuvia of Ptarth, whose startled eyes were the first to fall upon him, it seemed that she was looking upon John Carter himself, so strangely similar to the fighting of the father was that of the son.
