How Sir Launcelot rode with a damosel and slew a knight that distressed all ladies and also a villain that kept a bridge.
Now turn we unto Sir Launcelot, that rode with the damosel in a fair highway. Sir, said the damosel, here by this way haunteth a knight that distressed all ladies and gentlewomen, and at the least he robbeth them or lieth by them. What, said Sir Launcelot, is he a thief and a knight and a ravisher of women? he doth shame unto the order of knighthood, and contrary unto his oath; it is pity that he liveth. But, fair damosel, ye shall ride on afore, yourself, and I will keep myself in covert, and if that he trouble you or distress you I shall be your rescue and learn him to be ruled as a knight.
