Vinyarion
From Tolkien Gateway
Vinyarion was the son of King Aldamir of Gondor. In his father's time, war erupted between Gondor and the southern lands, and Aldamir was slain in that war. Vinyarion led Gondor's armies to avenge Aldamir's death, and overran the Haradrim. In token of this great victory, Vinyarion ruled under the name Hyarmendacil II, a name meaning 'South-victor'.
