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.
Fathers of the Dwarves It is told in The Silmarillion that the Vala Aulë created the Dwarves because he was impatient for the arising of the Children of Ilúvatar (Elves and Men). He created seven Dwarves, and was teaching them the language he had devised for them (Khuzdul) when Ilúvatar confronted him. Aulë offered his creations to Ilúvatar, who accepted them and gave them life.
