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.
The host was prepared, therefore, and at a meeting of his council King Arthur made his nephew, Sir Mordred, Regent of Britain, to rule in the king's place while he should be abroad; and Queen Gwenevere he placed under the governance of Sir Mordred, as well as the officers of the court.
When they had passed the sea and landed in the coasts of Sir Lancelot's country, Sir Gawaine ordered his knights to go through the nearer parts, burning the houses of the people and wasting their lands. This he did in order to enrage Sir Lancelot against the king, so that he would not listen quietly to any demand which the king might make of him.
Word was brought to Sir Lancelot of the landing of King Arthur and the plundering and wasting of the land, but for some days he would do naught; for he was loath to take up arms against the king he loved, who had made him a knight.
At length Sir Bors came to him, and with that knight were others, as Sir Lunel of the Brake, Sir Magus of Pol, and Sir Alan of the Stones with his six mighty brothers.
'My lord, Sir Lancelot,' said Sir Bors, 'it is great shame that we suffer them to ride over our lands, burning the homes of our folk and destroying the crops in the fields.'
