The smile upon the prefect’s face changed to sudden sternness.
“Trifle not with Roman justice, girl,” he said, “I demand the keeping of thy word.”
“It is kept,” replied the princess. “Helena of Britain is the cause and motive of this revolt against Rome. If it be rebellion for a free prince to claim his own, if it be rebellion for a prince to withstand for the sake of his people the unjust demands of the conqueror, if it be rebellion for one who loveth her father to urge that father to valiant deeds in defence of the liberties of the land over which he ruleth as king, then am I a rebel, for I have done all these, and only because of my words did the king, my father, take up arms against the might and power of Rome. I am the chief rebel. Do with me as thou wilt.”
And now the prefect saw that the girl spoke the truth, and that she had indeed kept her pledge.
“Thy father and his city are pardoned,” he announced after a few moments of deliberation. “Remain thou here, thou and thy companions, as hostages for Britain, until such time as I shall determine upon the punishment due to one who is so fierce a rebel against the power of Rome.”
So the siege of Camalodunum was raised, and the bloodless rebellion ended. Constantius the prefect took up his residence for a while within King Coel’s city, and at last returned to his command in Gaul and Spain, well pleased with the spirit of the little maiden whom, so he claimed, he still held in his power as the prisoner of Rome.
Constantius the prefect came again to Britain, and with a greater following, fully ten years after King Coel’s revolt, for now, again, rebellion was afoot in the island province.
Carausius the admiral, biding his time, sought at last to carry out his scheme of sole supremacy. Sailing with his entire war-fleet to Britain, he won the legions to his side, proclaimed himself Emperor of Britain, and defied the power of Rome.
So daring and successful was his move that Rome for a time was powerless. Carausius was recognized as “associate” emperor by Rome, until such time as she should be ready to punish his rebellion, and for seven years he reigned as emperor of Britain.
But ere this came to pass, Helena the princess had gone over to Gaul, and had become the wife of Constantius the prefect,—“Since only thus,” said he, “may I keep in safe custody this prisoner of Rome.”
