The Battle of Helm's Deep always springs to mind but specifically when the Elves turn up in support...
Quote:Haldir: I bring word from Lord Elrond of Rivendell. An Alliance once existed between Elves and Men. Long ago we fought and died together. We come to honor that allegiance.
Aragorn: Mae govannen, Haldir. You are most welcome.
Haldir: We are proud to fight alongside Men once more.
..and the subsequent scene when Haldir is struck down and the film slows down to slow motion, quite moving.
