Peter Jackson’s The Lord of the Rings trilogy, particularly The Return of the King, dazzles with epic battles. The pivotal clash at Pelennor Fields showcases the valor of Gondorians and Rohirrim against a coalition of adversaries. Amidst this chaos, Aragorn's trump card, the Army of the Dead, emerges as a game-changer.

Referred to as the Dead Men of Dunharrow in the source material, this spectral legion, bound by a curse due to past betrayal, aids Aragorn in a critical juncture. However, his choice to release them post-victory triggers speculation among Lord of the Rings enthusiasts. Why not deploy them against Sauron's forces in Mordor? The answer delves into Aragorn's principles and foresight.

Aragorn's Unyielding Honor and Oath

Aragorn's character is defined by a sense of duty rather than a thirst for power. Despite being Gondor's rightful king, he hesitates to embrace the crown. His journey through the Paths of the Dead underscores his unwavering commitment to fulfilling obligations. After the Dead Men's pivotal intervention, Aragorn's decision to release them reflects his adherence to honor and respect for their oath.

Releasing the Army of the Dead was a testament to Aragorn's integrity. By setting them free, he upholds the sanctity of their initial pledge to aid Gondor. Forcing them to continue to Mordor would have defied the essence of their oath and tainted Aragorn's noble cause.

Sauron's Corrupting Influence

Originating as the Men of the Mountains before their cursed existence, Sauron's shadow loomed over the Dead Men's past. Their susceptibility to corruption under Sauron's sway posed a substantial risk. Bringing them to Mordor could have exposed them to malevolent influences, potentially turning them against Aragorn and his allies. The specter of Sauron's manipulative powers cast a shadow of doubt over the wisdom of unleashing the Army of the Dead in Mordor.

Discrepancy Between Book and Film

In Tolkien's narrative, the Army of the Dead's role contrasts starkly with Jackson's cinematic portrayal. While the movie depicts them as an unstoppable force in battle, the book illustrates a more strategic application. The fear instilled by the Dead Men's mere presence was sufficient to rout Sauron's forces, showcasing a different facet of their potency. Aragorn's redirection of the Army towards Pelagir exemplifies their pivotal but subdued involvement, diverging from the grandiose battles depicted in the film adaptation.

Ultimately, Aragorn's decision not to utilize the Army of the Dead in the assault on Mordor stemmed from a blend of ethical considerations, strategic foresight, and a nuanced understanding of the risks involved. While their spectral prowess remained a tempting asset, the potential consequences outweighed the immediate advantages, leading Aragorn to chart a different path to victory.
