Ten was the number of these battles which he fought in the north, six against the Saxon pirates and four against the wild cats of Caledonia, whom men call Picts and Scots, and who had ventured south in greater numbers as soon as they heard how the king warred with his lords and the rich land was open to plunder. Two others he fought in the south, one against an insolent band of pirates who dared even to attack his palace-city of Caerleon-upon-Usk. But so heavy and deadly a blow did he strike at them then, that from that battle barely a dozen pagans were left to flee like fire to their ships. Not without loss of many of his brave warriors did Arthur win these battles, for the pagans were good men of their hands and not easily were they beaten. Saddest of all was the loss of the noble Geraint, who, thrusting back the pirates once again from the harbour of Llongporth, got his death there with many of his valiant men. When the fame of King Arthur's prowess and the might of his knights had gone abroad among the pagans, they were afraid and would not venture in great numbers to invade the land again, and there was peace and rest in Britain for a space. Then Sir Gawaine, remembering his hatred of Sir Lancelot, persuaded the king to make him ready another host, with which to invade the land of Brittany where Sir Lancelot ruled his kingdom. For a long time the king would not listen to his advice, and the queen, with all her power, strove against Sir Gawaine. But that knight and his large following of knights and men-at-arms had been of great service in the recent wars against the pagans, and the king could not wholly refuse to listen to Sir Gawaine's demands. Also Sir Mordred added his words to those of his brother, and said that men who came from Brittany said that Sir Lancelot was getting him ready a large army, and training many men, although he was at peace with his neighbours in Gaul. But the rumour went, as Sir Mordred reported, that Sir Lancelot was only waiting his time, and when King Arthur should be more than usually pressed by his pagan foes, Sir Lancelot and his great host would sail swiftly across the sea and seize the kingdom of Britain, when Arthur, exhausted by war, would be unable to withstand the fresh warriors of Sir Lancelot, and would lose both his queen and his crown. For a time the king would not suffer these evil rumours to be mentioned in his presence, but many of his counsellors thought there was much truth in them. At length, so persistent was Sir Mordred and those whom he craftily persuaded to believe him, that for sheer weariness the king consented to take an army across to Brittany, and to demand that Sir Lancelot should own that the king was his overlord, and that he should do homage to King Arthur for his kingdom.
