Slowly, Dilecta's defenders fell back before the greater number of nobles, soldiers, and guardsmen who were summoned from other parts of the palace. Back toward the little door they fell, while shoulder to shoulder with the gladiators and with Maximus Praeclarus and Hasta and Metellus, Tarzan fought and the great apes spread consternation among all because of their disposition to attack friend as well as foe. And out upon the Via Principalis the crowd surged and the great gates gave to a shrieking mob that poured into the palace grounds, overwhelming the guards, trampling them--trampling their own dead and their own living. But the veteran legionaries who composed the palace guard made a new stand at the entrance to the palace. Once more they checked the undisciplined rabble, which had by now grown to such proportions that the revolting troops, who had joined them, were lost in their midst. The guard had dragged an onager to the palace steps and were discharging stones into the midst of the crowd, which continued to rush forward to fall upon the pikes of the palace defenders. In the distance trumpets sounded from the direction of the Porta Decumana, and from the Porta Principalis Dextra came the sound of advancing troops. At first those upon the outskirts of the mob, who had heard these sounds, did not interpret them correctly. They cheered and shouted. These cowards that hang always upon the fringe of every crowd, letting others take the risks and do the fighting for them, thought that more troops had revolted and that the reënforcements were for them. But their joy was short-lived, for the first century that swung into the Via Principalis from the Porta Decumana fell upon them with pike and sword until those who were not slain escaped, screaming, in all directions. Century after century came at the double. They cleared the Via Principalis and fell upon the mob within the palace court until the revolt dissolved into screaming individuals fleeing through the darkness of the palace grounds, seeking any shelter that they might find, while terrible legionaries pursued them with flaming torches and bloody swords. Back into the little room from which they had come fell Tarzan and his followers. The doorway was small and it was not difficult for a few men to hold it, but when they would have retreated through the window they had entered and gone back into the palace grounds to seek escape across the walls in the shadows of the old trees, they saw the ground swarming with legionaries and realized that the back of the revolt had been broken.
