He had been there no time at all when he saw two huge and frightening giants approaching, armed like champions for combat, with naked and exposed heads. They were bearing good strong shields and wore double-linked hauberks, and each had a fine sharp sword in his hand. When they saw Lancelot, they told him he was dead if he did not surrender. He looked at them and saw they were not knights; he said he was not frightened of two peasants and struck the first he met so hard he split his shield like a rag and drove his sword through his head; he fell dead.
