§ Of Beren and Lúthien The Silmarillion

There Beren buried his fathers bones, and raised a cairn of boulders above him, and swore upon it an oath of vengeance. First there for he pursued the Orcs that had slain his father and his kinsmen, and he found their camp by night at Rivil's Well above the Fen of Serech, and because of his wood craft he came near to their fire unseen. There their captain made boast of his deeds, and he held up the hand of Barahir that he had cut off as a token for Sauron that their mission was fulfilled; and the ring of Felagund was on that hand. Then Beren sprang from behind rock, and slew captain, and taking the hand and the ring he escaped, being defended by fate for the Orcs were dismayed, and their arrows wild.
