§ Of Túrin Turambar The Silmarillion

When it became known to Orodreth that the Mormegil was in truth the son of Húrin Thalion he gave him great honour, and Túrin became mighty among the people of Nargothrond. But he had no liking for their manner of warfare, of ambush and stealth and secret arrow, and he yearned for brave strokes and battle in the open; and his counsels weighed with the King ever the longer the more. In those days the Elves of Nargothrond forsook their secrecy and went openly to battle, and great store of weapons were made; and by the counsel of Túrin the Noldor built a mighty bridge over the Narog from the Doors of Felagund, for the swifter passage of their arms. Then the servants of Angband were driven out of all the land between Narog and Sirion eastward, and westward to the Nenning and the desolate Falas; and though Gwindor spoke ever against Túrin in the council of the King, holding it an ill policy, he fell into dishonour and none heeded him, for his strength was small and he was no longer forward in arms. Thus Nargothrond was revealed to the wrath and hatred of Morgoth; but still at Túrin's prayer his true name was not spoken, and though the fame of his deeds came into Doriath and to the ears of Thingol, rumour spoke only of the Black Sword of Nargothrond.
