Then he cast aside his shield and vielwed and axe two-handed; and it is sung that the axe smoked of the black-blood of the troll-Guard of Gothmog, until it withered; and each time he slew, Hùrin cried Aüre entuluva! Day shall come again!
Seventy times he uttered that cry: but they took him at last alive, by the command of Morgoth..."
