The Mouth of Sauron

The Lieutenant of Barad-dur, also known as the Mouth of Sauron, was a black Numenorean who could not resist the evil knowledge of Sauron. He announced himself herald and ambassador, the mouth of Sauron and messenger of Mordor, when he came to meet the approaching army from Gondor outside the Black Gates. He showed them items belonging to Frodo, told them to agree to Sauron's terms and surrender. Gandalf rejected Sauron´s proposal and said: "Get you gone, for your embassy is over and death is near to you. We did not come here to waste words in treating with Sauron, faithless and accursed; still less with one of his slaves. Begone!". The Lieutenant was certainly killed in the battle of Cormallen or in the events thereafter.
