Turin and Beleg

"Beleg drew his sword Anglachel, and with it he cut the fetters that bound Túrin; but fate that day was more strong, for the blade slipped as he cut the shackles, and Túrin’s foot was pricked. Then he was aroused into a sudden wakefulness of rage and fear, and seeing one bending over him with naked blade he leapt up with a great cry, believing that Orcs were come again to torment him; and grappling with him in the darkness he seized Anglachel and slew Beleg Cúthalion thinking him a foe."--J.R.R. Tolkien
