On 10 March, T.A. 3019, Duinhir led a contingent of five hundred bowmen as well as his two sons, Duilin and Derufin, into Minas Tirith to fight in the upcoming battle. Sadly, Lord Duinhir lost both of his sons in the fray (on 15 March) when they were trampled by mûmakil while attempting to shoot out the monsters' eyes.
Duinhir means "River-lord" in Sindarin.
