<P> The Battle of the Hornburg is also a key part of Peter Jackson's film adaptation, The Lord of the Rings: The Two Towers . </P> <P> In the context of the film, it is referred to as the Battle of Helm's Deep, and like Bakshi, Jackson identifies "Helm's Deep" with the fortress itself . As Gríma says to Saruman: "Théoden will not stay at Edoras...They will flee to Helm's Deep, the great fortress of Rohan ." </P> <P> 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 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 . </P> <P> Peter Jackson gave himself a cameo appearance as one of the Rohirrim; he throws a javelin at the Uruks . Producer Barrie Osborne has a similar cameo, as a Rohirrim throwing a rock down on them . </P>
