who led the elves at helm's deep
Battle of the Hornburg In the movie, 10,000 of Saruman's Uruk-hai (with no orcs of other races, Dunlendings or wargs to accompany them) lay siege to the fortress, which is defended by around 300 Rohirrim (before the battle, Legolas states their strength to be "three hundred against ten thousand", but he may have meant at that time, as more were fleeing to the fortress). Soon after, however, a large group of the Elves of Lórien join the defences. Elrond, at the prompting of Galadriel, sends the Elves under the command of Haldir of Lórien to reinforce the defence of the keep. During the battle, nearly all of the Elves are killed, including Haldir. The defenders suffer heavy losses, but hold out until dawn, when Gandalf arrives with 2,000[4] riders led by Éomer, who finally turn the tide of the battle and send Saruman's forces into retreat. In the Extended DVD version, the Huorns make an appearance, massacring the fleeing Uruk-hai after the battle, but were absent from the theatrical cut.
Middle-earth The Valar withdrew from direct involvement in the affairs of Middle-earth after the defeat of Morgoth, but in later years they sent the wizards or Istari to help in the struggle against Sauron. The most important wizards were Gandalf the Grey and Saruman the White. Gandalf remained true to his mission and proved crucial in the fight against Sauron. Saruman, however, became corrupted and sought to establish himself as a rival to Sauron for absolute power in Middle-earth. Other races involved in the struggle against evil were Dwarves, Ents and most famously Hobbits. The early stages of the conflict are chronicled in The Silmarillion, while the final stages of the struggle to defeat Sauron are told in The Hobbit and in The Lord of the Rings.
