Mordred and Agravaine, trying to prove Lancelot's affair with Guenever, decide on the tried-and-true method of "let's catch them in the act." They also take along twelve armored knights with them, just in case. The fourteen slam on the chamber door, shouting for the naked and unarmed Lancelot to surrender. Does he give in? Fuck no, cause he's Lancelot. He tricks one of them into the room, kills him, takes his weapons and armor, and even gets off a one-liner as he takes the 13-to-1 odds.
Ah sirs, said Sir Launcelot, is there none other grace with you? then keep yourself.
So then Sir Launcelot set all open the chamber door, and mightily and knightly he strode in amongst them; and anon at the first buffet he slew Sir Agravaine. And twelve of his fellows after, within a little while after, he laid them cold to the earth, for there was none of the twelve that might stand Sir Launcelot one buffet. Also Sir Launcelot wounded Sir Mordred, and he fled with all his might.
