That same night the band came to the castle of the prince with whom Meriadus was at war. He welcomed them very gladly, and gave them lodging in his tower. By their aid he had good hope to bring this quarrel to an end. Very early in the morning the host came together to set the battle in array. With clash of mail and noise of horns they issued from the city gate, Gugemar riding at their head. They drew before the castle where Meriadus lay in strength, and sought to take it by storm. But the keep was very strong, and Meriadus bore himself as a stout and valiant knight. So Gugemar, like a wary captain, sat himself down before the town, till all the folk of that place were deemed by friend and sergeant to be weak with hunger. Then they took that high keep with the sword, and burnt it with fire. The lord thereof they slew in his own hall; but Gugemar came forth, after such labours as you have heard, bearing his lady with him, to return in peace to his own land.
From this adventure that I have told you, has come the Lay that minstrels chant to harp and viol—fair is that song and sweet the tune.
