Presently afterwards, they made a last attack upon the city, and entered by the walls on every side; and as the men were rushing to the pillage, came the Duchess forth, with many ladies and damsels, and kneeled before King Arthur; and besought him to receive their submission. To whom the king made answer, with a noble countenance, "Madam, be well assured that none shall harm ye, or your ladies; neither shall any that belong to thee be hurt; but the Duke must abide my judgment." Then he commanded to stay the assault and took the keys from the Duke's eldest son, who brought them kneeling. Anon the Duke was sent a prisoner to Dover for his life, and rents and taxes were assigned for dowry of the Duchess and her children.
Then went he on with all his hosts, winning all towns and castles, and wasting them that refused obedience, till he came to Viterbo. From thence he sent to Rome, to ask the senators whether they would receive him for their lord and governor. In answer, came out to him all the Senate who remained alive, and the Cardinals, with a majestic retinue and procession; and laying great treasures at his feet, they prayed him to come in at once to Rome, and there be peaceably crowned as Emperor. "At this next Christmas," said King Arthur, "will I be crowned, and hold my Round Table in your city."
Anon he entered Rome, in mighty pomp and state; and after him came all his hosts, and his knights, and princes, and great lords, arrayed in gold and jewels, such as never were beheld before. And then was he crowned Emperor by the Pope's hands, with all the highest solemnity that could be made.
Then after his coronation, he abode in Rome for a season, settling his lands and giving kingdoms to his knights and servants, to each one after his deserving, and in such wise fashion that no man among them all complained. Also he made many dukes and earls, and loaded all his men-at-arms with riches and great treasures.
When all this was done, the lords and knights, and all the men of great estate, came together before him, and said, "Noble Emperor! by the blessing of Eternal God, thy mortal warfare is all finished, and thy conquests all achieved; for now in all the world is none so great and mighty as to dare make war with thee. Wherefore we beseech and heartily pray thee of thy noble grace, to turn thee homeward, and give us also leave to see our wives and homes again, for now we have been from them a long season, and all thy journey is completed with great honor and worship."
"Ye say well," replied he, "and to tempt God is no wisdom; therefore make ready in all haste, and turn we home to England."
So King Arthur returned with his knights and lords and armies, in great triumph and joy, through all the countries he had conquered, and commanded that no man, upon pain of death, should rob or do any violence by the way. And crossing the sea, he came at length to Sandwich, where Queen Guinevere received him, and made great joy at his arrival. And through all the realm of Britain was there such rejoicing as no tongue can tell.
