How the Green Knight dealt the blow
“For sooth,” quoth the other, “so fiercely thou speakest I will no longer let thine errand wait its reward.” Then he braced himself to strike, frowning with lips and brow, ’twas no marvel that he who hoped for no rescue misliked him. He lifted the axe lightly and let it fall with the edge of the blade on the bare neck. Though he struck swiftly it hurt him no more than on the one side where it severed the skin. The sharp blade cut into the flesh so that the blood ran over his shoulder to the ground. And when the knight saw the blood staining the snow, he sprang forth, swift-foot, more than a spear’s length, seized his helmet and set it on his head, cast his shield over his shoulder, drew out his bright sword, and spake boldly (never since he was born was he half so blithe), “Stop, Sir Knight, bid me no more blows. I have stood a stroke here without flinching, and if thou give me another, I shall requite thee, and give thee as good again. By the covenant made betwixt us in Arthur’s hall but one blow falls to me here. Halt, therefore.”
