The Battle of Helm's Deep, also called the Battle of the Hornburg, is a fictional battle in J. R. R. Tolkien's The Lord of the Rings, that saw the total destruction of the forces of the WizardSaruman by the army of Rohan, assisted by a forest of tree-like Huorns. , a steep-sided limestone valley in the West of England, seen here in the 1890s Helm's Deep was a valley in the north-western White Mountains of Middle-earth. Helm's Deep, with its fortress the Hornburg, becomes the refuge of some of the army of Rohan, the Rohirrim, under King Théoden, from assault by the forces of Saruman. Although Théoden says that "the Hornburg has never fallen to assault," in the battle a massive army of Uruk-hai and Dunlendings sent by Saruman almost overwhelms the defences. Saruman's Orcs breach the fortress wall that blocks the valley by setting off an explosion in a culvert; Aragorn names it "Saruman's devilry" and "the fire of Orthanc"; the critic Tom Shippey calls it "a kind of gunpowder". The defenders hold out in the fortress until dawn, when Théoden and Aragorn lead a cavalry charge that drives the Orcs from the fortress. They are surprised to see the valley to the enemy's rear blocked by a forest of tree-like Huorns that have walked from Fangorn in the night. On the side of the valley are relieving forces assembled by Gandalf and Erkenbrand, a Rohirrim leader. These attack, driving the Orcs into the angry Huorn forest, from which the Orcs never emerge; the Huorns bury the Orcs's bodies in an earthen mound known as "Death's Down". Peter Jackson's 2002 makes the battle dramatic, following Tolkien's account quite closely, but with changes to the forces involved: the attackers do not include men or wargs, and the defenders include a group of Elf-warriors sent by Elrond, but except in the Extended DVD version do not include the Huorns. Tolkien based Helm's Deep on England's Cheddar Gorge, and its Glittering Caves of Aglarond on the cave complex that he had visited there.
Fictional geography
Helm's Deep is based on the Cheddar Gorge, a limestone gorge 400 feet deep in the Mendip Hills, with a large cave complex that Tolkien visited on his honeymoon in 1916 and revisited in 1940, and which he acknowledged as the original of the Glittering Caves of Aglarond at the head of Helm's Deep, behind the fortress. Helm's Deep is properly the narrow gorge or ravine at the head of a larger valley, but the name is also used for the fortifications at the mouth of the gorge and the larger valley below. The gorge, which wound deep into the White Mountains at the feet of the Thrihyrne mountain, led into the Glittering Caves of Aglarond, an extensive series of spectacular speleothems. In The Lord of the Rings, the DwarfGimli, who like all dwarves is well versed in geology, horrified that the caves are used only as a refuge, describes them lyrically: , and Mordor in the Third Age. Helm's Deep is at top left, at the north of the Ered Nimrais mountains. Isengard, Saruman's fortress, is across the Gap of Rohan to the north, as is Fangorn forest, home to the Ents and Huorns. The mouth of the gorge, Helm's Gate, was closed by the battlemented Deeping Wall, 20 feet tall, and wide enough for four men to stand abreast, with a culvert for the Deeping-stream which flowed down the valley. At one end of the wall the Hornburg castle stood on a spur of the mountain; a long stair led to its rear gate, and a long causeway led down forwards from its main gate. About two furlongs down from the gate was an outer trench and rampart, Helm's Dike, built right across the Deeping-coomb. Tolkien drew detailed sketches of the fortifications. The valley was named for King Helm Hammerhand of Rohan, when he and his people sought refuge from the invading Dunlendings under Wulf during the winter of.
Description
Background
Théoden had been released by the Wizard Gandalf from the influence of Gríma Wormtongue, his malevolent adviser and Saruman's spy. He then set out to the Fords of Isen, where his marshal Erkenbrand was fighting Saruman's forces. However, Théoden found out that his forces had been scattered. Gandalf advised him to take refuge in the Hornburg fortress of Helm's Deep. Gandalf then left on an unexplained errand. Théoden's army went to the area, where local people were commanded by a captain called Gamling the Old. Many of the men there were very old or young. The women and children of Théoden's capital Edoras were safe in Dunharrow, led by the King's niece Éowyn. The garrison of Helm's Deep consisted of some 1,000 men, but around 1,000 more defenders had arrived from across Rohan by the time of the battle. The enemy, Saruman's army, consisted of at least 10,000 Orcs and men, most marching from Isengard to Helm's Deep, and others heading to the Fords of Isen. An additional force of Men of Dunland joined the enemy.
The battle
The forces of Saruman, common Orcs, large Uruk-hai, "half-orcs and goblin-men", and Dunlendings, arrived at Helm's Deep on a stormy night. They stormed the first defence, Helm's Dike, forcing the defenders to fall back to the fortress. They attempted to break down the gate with a battering ram, but a sortie led by Aragorn and Éomer briefly scattered the attackers. The Orcs and Dunlendings raised ladders to scale the wall, but were held back by the Men of Rohan atop the wall. Orcs crept into the culvert and made a breach in the wall using a "blasting-fire" from Orthanc, perhaps "a kind of gunpowder"; Saruman's army rushed in. Some defenders retreated to the Glittering Caves of Aglarond, while others retreated to the Hornburg. Saruman's forces broke through the Hornburg gate just before dawn. At this moment, Helm's horn was sounded, and Théoden and Aragorn rode out, followed by all the Rohirrim left inside. They cut their way through the Orcs and drove them back from the fortress walls to Helm's Dike. As day dawned, both armies saw that a forest of angry, tree-like Huorns now filled the valley, trapping Saruman's army. Above them, Gandalf appeared on Shadowfax, with Erkenbrand and a thousand footsoldiers who had escaped from the Fords of Isen. They charged into the fray. The Dunlendings dropped their weapons, while the Orcs fled into the Huorn forest and were destroyed. Tolkien noted in a letter that he had created walking tree-creatures partly in response to his "bitter disappointment and disgust from schooldays with the shabby use made in Shakespeare's Macbeth of the coming of 'Great Birnam Wood to high Dunsinane hill': I longed to devise a setting in which the trees might really march to war". The Tolkien scholar Tom Shippey calls it a "shock" that the battle is decided in this way.
Aftermath
After the battle, the Dunlendings were given amnesty by Erkenbrand and allowed to return home. The Rohirrim required that all hostilities cease, and that the Dunlendings retreat behind the River Isen again and never recross while bearing arms. Before they were freed, though, the Dunlending captives were put to work in repairing the fortress. The bodies of the Orcs that had entered the forest of Huorns were never seen again; the Huorns had buried them in an earthen mound known as "Death's Down". Among the Rohirrim dead was Háma, captain of Théoden's personal guard and doorward of his hall; the Orcs had hewn his corpse, an atrocity that Théoden recalled during his later parley with Saruman. Gimli had been wounded, but had killed 42 Orcs to Legolas's 41.
Literary history
In Book III, ch. 5 of The Two Towers, Helm is described only as a "hero of old wars"; Tolkien did not envision him as a king when he wrote that chapter. Tolkien had not yet envisioned Helm's Deep in his first sketch for the decisive battle between Rohan and the forces of Saruman. In an outline published in The Treason of Isengard as “The Story Foreseen from Fangorn," the Rohirrim rode west at Gandalf's urging, as in the published text, but met the army of Saruman on the open plain. An indecisive battle ensued, after which the Rohirrim camped for the night, and woke to see the enemy surrounded and destroyed by a wood that had appeared overnight. In a 1958 letter to Rhona Beare, one of a group of enthusiasts, Tolkien stated that the Rohirrim "were not 'Mediaeval' in our sense", but that all the same "the styles of the Bayeux Tapestry fit them well enough", explaining that the soldiers in the tapestry are wearing chain-mail.
Later writings
After the publication of The Lord of the Rings, Tolkien wrote about the history of Rohan, in writings now collected by his son Christopher in Unfinished Tales. These state that the fortresses of Aglarond and Angrenost were built by Gondor to guard the shoulders of the Gap of Rohan. Like Angrenost to the north, it was initially well guarded, but as the population of Calenardhon dwindled it was not maintained and was left to a hereditary small guard who intermarried with Dunlendings. When Cirion, Steward of Gondor, gave Calenardhon to the Éothéod, Aglarond was transferred into the care of the Rohirrim, who named it Súthburg. The Gondorian guard was merged with that of Isengard. Guard duty of the Fords was initially shared between Gondor and Rohan, but later maintained only by the Rohirrim.
Adaptations
Peter Jackson's film
In Peter Jackson's 2002 film the keep was built into the mountainside and resembles a World War Ibunker, in keeping with Tolkien's history as a soldier in that war. The entrance to the Glittering Caves of Aglarond is within the Hornburg itself, rather than at the top of the deep behind the Deeping Wall as in the book. Further, the Uruk-hai assault the main gateway in a testudo, or locked-shields style formation, and the 'blasting fire' is depicted as gunpowder. The battle was filmed mainly at night, in frequent heavy natural rain or when necessary with artificial rain on the actors, for more than three months. The Helm's Deep set used some computer-generated imagery; some parts were constructed as full size sets; some shots used a 1/4 scale physical model, while more distant shots used a 1/85 scale model. In the final battle scene, Weta's "Massive" crowd simulation software and "Grunt" rendering software were used, with thousands of Uruk-hai modelled using Alias/Wavefront's "Maya" software. It has been described as one of the greatest battle scenes in film, combining "technical mastery, sweeping spectacle and tonal balance". In the film, 10,000 of Saruman's Uruk-hai lay siege to the fortress, defended by around 300 Rohirrim. Soon after, however, a large group of the Elves of Lothlórien join the defences, sent by Elrond, at Galadriel's prompting. The defenders suffer heavy losses, but hold out until dawn, when Gandalf arrives with 2,000 riders led by Éomer, who turn the tide of the battle and rout Saruman's forces. In the original script of the film, Elrond and Arwen had gone to see Galadriel in person, and it was Arwen who led the Elves to fight alongside the Rohan defenders. Jackson rejected Arwen's involvement, revising her character from a "warrior princess" to a role closer to that of the book, but kept the Elves in the battle.
