When J.R.R. Tolkien penned the climactic clash at the roots of the Lonely Mountain, he cemented one of the most debated nomenclature choices in fantasy history. The conflict that decides the fate of Erebor features a chaotic mix of dwarves, men, elves, goblins, and wolves, but pinning down who officially qualifies as an army changes depending on whether you ask a literary purist or a film fan.
Understanding the real composition of this clash requires looking past casual assumptions and examining the text of The Hobbit alongside its cinematic adaptations. The core confusion stems from Tolkien's own shifting definitions and the stark differences between written canon and Peter Jackson's blockbuster interpretation.
Dissecting Tolkien's Original Text
In Chapter 18 of The Hobbit, titled "The Clouds Burst," Tolkien explicitly names the combatants. He states that upon one side were the Goblins and the wild Wolves, and upon the other were Elves, Men, and Dwarves. This yields five distinct factions:
- The Goblins: A massive, unified host of orcs from the Misty Mountains and Grey Mountains, driven by a thirst for vengeance after the death of the Great Goblin and drawn by the scent of unclaimed dragon gold.
- The Wild Wolves (Wargs): Intelligent, malicious wolf-like creatures of the North that act as independent combatants rather than mere mounts, seeking payback for past burns dealt by Thorin's company.
- The Dwarves: Comprising both Thorin's original company within Erebor and Dáin Ironfoot's heavily armored host of five hundred warriors marching from the Iron Hills.
- The Elves: The Silvan Elves of Mirkwood, a disciplined host of spearmen and archers led by Thranduil.
- The Men: The surviving Lake-men of Esgaroth alongside the emerging Men of Dale, led by Bard the Bowman.
Purists often point out structural oddities in this list. For instance, Thorin's thirteen dwarves hardly constitute a full military army on their own until Dáin arrives. Similarly, treating the Wargs as an equal counterweight to thousands of disciplined elves raises tactical eyebrows. Yet within Tolkien's mythic framework, distinct species often equated to sovereign military units.
The Cinematic Shift: Book Versus Film Adaptations
Adaptations of Middle-earth have repeatedly reinterpreted the roster to fit visual storytelling. The 1977 Rankin/Bass animated film dropped the Wargs from the primary count and instead substituted the Great Eagles as the fifth army, a popular misconception that lingered for generations.
Peter Jackson's 2014 cinematic adaptation altered the equation entirely to suit a massive blockbuster scale. In the film version, the forces of evil are split into two distinct staging armies to create greater tactical depth:
- The primary host of Azog the Defiler emerging from Dol Guldur.
- The secondary, surprise reinforcement army of Gundabad orcs led by Bolg.
This cinematic restructuring replaces the book's inclusion of Wargs as a core faction, framing the wild wolves instead as cavalry units integrated directly into the goblin ranks. Meanwhile, independent powerhouses like Beorn and the Great Eagles operate as unpredictable, game-changing reinforcements rather than formal state armies.
Tactical Realities of the Conflict
No matter which version you look at, the strategic layout of the battle makes little sense without acknowledging the friction between the free peoples. Before the goblins ever crested the valley, the men of Lake-town and the wood-elves had laid siege to Erebor. They were ready to fight each other over Thorin's gold.
The arrival of the goblin horde forces an immediate, desperate alliance. This tactical pivot highlights a recurring theme across Tolkien's works: external darkness forces fractured societies to mend old grievances. The dwarves, holding the bottleneck of the mountain gate, combine forces with Bard's spearmen and Thranduil's archers to form a defensive crescent.
The engagement is nearly lost until vertical envelopment and unexpected heavy hitters shift the momentum. The intervention of Beorn—transforming into a massive bear that tears through Bolg's bodyguard—coupled with the aerial assault of the Great Eagles, breaks the enemy lines. Without these disruptive wild cards, the coordinated numerical superiority of the northern orcs would have crushed the exhausted alliance.

Common Misconceptions to Avoid
Readers and viewers frequently misattribute leadership or army sizes because of fast-paced storytelling.
- Hobbits are not an army: Bilbo Baggins plays a pivotal role with his magic ring, but he fights as an individual scout, not a military unit.
- Wargs are not ordinary wolves: In Tolkien's legendarium, Wargs possess their own crude speech and calculated malice, separating them from normal fauna or domesticated mounts.
- The Eagles are auxiliary: Despite their massive impact, the Great Eagles function as a strategic reserve rather than one of the core five standing armies named in the text.
Frequently Asked Questions
Why didn't the dwarves and elves fight each other?
They were on the verge of open warfare over the treasure of Erebor when scout reports revealed the approaching goblin army. Recognizing mutual annihilation, they pooled their shields and arrows against a common enemy.
Are Wargs sentient in the books?
Yes. Unlike typical fantasy monsters or mere mounts, Tolkien's Wargs possess independent intelligence, cunning, and an organized society that plots alongside goblins.
How many total combatants fought in the battle?
While Tolkien left exact headcounts vague outside of Dáin's 500 ironclad dwarves, cinematic breakdowns and textual scale estimate that the combined free peoples numbered around twenty thousand, facing an innumerable sea of tens of thousands of goblins and wargs.
What happened to Thorin during the clash?
Thorin fought valiantly out of the gates of Erebor alongside his company, but he sustained mortal wounds while defending the line, ultimately passing away shortly after the victory was secured.
