After Arthur had conquered Norway, and firmly established his justice in the land, he chose of his host those men who were the most valiant and ready in battle, and assembled them by the sea. He brought to the same haven many ships and barges, together with such mariners as were needful for his purpose. When a quiet time was come, with a fortunate wind, Arthur crossed the sea into Denmark; for the realm was very greatly to his desire. Acil, the Danish king, considered the Britons and the folk from Norway. He considered Arthur, who had prevailed against so many kings. Acil knew and was persuaded that Arthur was mightier than he. He had no mind to suffer hurt himself, or to see his goodly heritage spoiled in a useless quarrel. What did it profit to waste wealth and honour alike, to behold slain friends and ruined towers? Acil wrought well and speedily. He sought peace, and ensued it. He gave costly gifts, and made promises which were larger still, till by reason of his words, his prayers, and supplications, concord was established between Arthur and the king. Acil paid fealty and homage, he became Arthur's man, and owned that of Arthur's grace he held his fief. King Arthur rejoiced greatly at this adventure, and of the conquest he had made. He desired honour the more greedily because of the worship he had gained. From out of Denmark he chose, by hundreds and by thousands, the stoutest knights and archers he could find. These he joined to his host, purposing to lead this fair company into France. Without any long tarrying the king acted on his purpose. Towns, cities, and castles fell before him, so that Flanders and the country about Boulogne were speedily in his power. Arthur was a prudent captain. He perceived no profit in wasting his own realm, burning his towns, and stealing from his very purse. His eyes were in every place, and much was forbidden by his commandment. No soldier might rob nor pill. If there was need of raiment, meat, or provand, then must he buy with good minted coin in the market. Nothing he dared to destroy or steal.
