In this pivotal chapter, the fate of Middle-earth hangs in the balance as the leaders of the free peoples convene to discuss their final strategies against the dark forces of Sauron. The chapter opens with Gandalf and Pippin arriving in Minas Tirith, where they witness the city preparing for a siege. The atmosphere is tense, with the threat of Sauron's army looming on the horizon. Gandalf, as a beacon of hope, rallies the defenders and emphasizes the need for unity among all races of Middle-earth.

The council gathers at the great hall of the Gondorian city, where Aragorn, Legolas, Gimli, and other key figures are present. The discussion revolves around the dire situation they face, particularly the overwhelming strength of Sauron’s forces and the looming assault on Minas Tirith. Gandalf stresses the importance of taking action against Sauron before the One Ring can be reclaimed, as its destruction is essential to their victory. The leaders recognize that the only way to distract Sauron from Frodo's quest to destroy the Ring is to launch a frontal assault against his forces.

The chapter highlights the tension and urgency of the situation, showcasing the differing perspectives of the characters involved. There are moments of doubt and despair, especially from Boromir's brother, Faramir, who feels the weight of leadership and the responsibility to protect his city. Yet, hope is reignited as Aragorn reveals his intentions to claim his birthright as the King of Gondor, which inspires those around him.

As the debate continues, the leaders discuss various strategies, weighing the risks of their options. They realize that they cannot wait for Sauron to strike first; they must take the initiative and draw the enemy's attention away from Frodo and Sam, who are on their perilous journey to Mount Doom. The plan is formed to march on the Black Gate of Mordor, creating a diversion that will buy Frodo and Sam the time they need to fulfill their critical mission.

The chapter culminates in a powerful sense of resolve among the leaders, as they prepare to face the darkness head-on. The camaraderie and sense of duty among the characters are palpable, underscoring the themes of sacrifice and bravery. They recognize that their fates are intertwined, and the success of their mission depends not just on their individual strengths but on their unity against a common foe. The Last Debate sets the stage for the climactic battles to come, embodying the spirit of hope even in the face of overwhelming odds as the fate of Middle-earth hangs in the balance.
