'With my lance I struck the cup, and instantly there was a great peal of thunder, so that I trembled for fear. And instantly there came a great storm of rain and of hail. The hailstones were so large and so hard that neither man nor beast could live through that storm, for they would have slain them, so fiercely did they beat. And the way that I escaped was this. I placed the beak of my shield over the head and neck of my horse, while I held the upper part over my own head. Thus did we withstand the storm, though the flanks of my horse were sore wounded. 'Then the sky cleared, the sun came out, and a flock of birds began to sing on a tree beside the fountain. And surely no one has heard such entrancing music before or since. So charmed was I with listening, that I noticed not at first a low rumbling which seemed to come nearer and nearer. 'And suddenly I heard a voice approaching me, and I looked round just as a big knight in sky-blue armour rode swiftly up the valley. '"O knight," cried he, "what ill have I done to thee, that thou usest me so evilly? Knowest thou not that the storm which thou hast sent by evil magic hath slain my best flocks on the hills, and beaten to death all my men that were without shelter?" 'He came at me furiously. I put my lance in rest and spurred towards him, and we came together with so great an onset that I was carried far beyond the crupper of my horse. 'Then the knight, taking no further notice of me, passed the shaft of his lance through the bridle of my horse, and so rode swiftly away. And it moved me to anger to think he despised me so much as not even to despoil me of my sword. 'Very depressed of spirit was I as I took my way back to the castle of Sir Dewin. And as I passed through the wood I came to a glade, in the midst of which was a green mound. And as I passed it I heard laughter, which seemed to come from the earth. And I heard a voice sneering and mocking me. And I guessed it was the voice of a troll or moundman whom I could not see, who lived in the hillock, and I wonder I did not go mad with the shame of his derision. 'And I had not the spirit to go to try to break into the mound, lest he should work magic and more disaster upon me. So I left that glade, with the sound of his hoarse laughter ringing in my ears. 'I reached the castle of Sir Dewin, and well entertained was I, and rested for the remainder of that day. And full of courtesy was Sir Dewin and his household, for none of them referred to my encounter, and to the fact that I had come back without a horse. And when I rose next day, there was a dark bay palfrey, ready saddled, waiting in the courtyard for me. That horse I still possess, though the sight of him ever brings back the memory of my defeat.
