Then Launcelot unbarred the door, and with his left hand he held it open a little, so that but one man might come in at once; and so there came striding a good knight, a much man and large, and his name was Colgrevance of Gore, and he with a sword struck at Sir Launcelot mightily; and he put aside the stroke, and gave him such a buffet upon the helmet, that he fell grovelling dead within the chamber door. And then Sir Launcelot with great might drew that dead knight within the chamber door; and Sir Launcelot with help of the queen and her ladies was lightly armed in Sir Colgrevance’s armour.
