Rohan and Gondor
Rohan and Gondor is the ancient alliance between the horse-lords of the Riddermark and the southern realm of Gondor, a bond of mutual aid and shared blood that becomes the decisive military and moral axis of the War of the Ring. The relationship is defined by the Oath of Eorl, by which the Rohirrim pledged to come to Gondor's aid in its hour of need, and by Gondor's desperate reliance on that promise as its eastern defenses collapse. The alliance is tested, strained, and ultimately vindicated through the Ride of the Rohirrim to the Pelennor Fields, the crowning of Aragorn as King of the Reunited Kingdom, and the final restoration of peace in which the two realms stand as equal partners under a single crown.
The Oath of Eorl and the Dream of the Sword
The alliance between Rohan and Gondor rests on the Oath of Eorl, the ancient pledge by which the horse-lords of the North agreed to ride to Gondor's aid whenever it called. This bond is invoked at the very outset of the War of the Ring, when Boromir, son of Denethor, Lord of Minas Tirith, arrives at the Council of Elrond bearing a dream that has come to him and to his brother Faramir. In that dream, the eastern sky grows dark with thunder while a pale light lingers in the West, and out of it a voice cries: "Seek for the Sword that was broken: In Imladris it dwells; There shall be counsels taken Stronger than Morgul-spells." The dream speaks of Isildur's Bane awakening and a Halfling standing forth, words that Boromir and Faramir could scarcely understand. They spoke of it to their father, Denethor, wise in the lore of Gondor, who could only tell them that Imladris was the old Elvish name for a far northern dale where Elrond the Halfelven dwelt, greatest of lore-masters. Because the way was full of doubt and danger, Boromir took the journey upon himself, though his father was loath to give him leave, and he wandered long by forgotten roads seeking the house of Elrond. His errand was not to seek allies in war, for he knew that Elrond's might lay in wisdom rather than weapons; he came to ask for counsel and the unravelling of hard words. Yet the very fact that Gondor's heir rode a hundred and ten days alone through dangerous leagues to find Elrond reveals how desperate Gondor's need had become, and how much it still counted on the old alliances of the West.
The Breaking of the Eastern Defenses
The alliance is tested to its breaking point in the days before the Battle of Helm's Deep, when the eastern defenses of Rohan collapse under the combined assault of Saruman's forces. A weary messenger with dinted helm and cloven shield rides back to the Rohirrim, gasping for breath, and asks for Éomer. He reports that things have gone evilly since Théodred fell: the Rohirrim were driven back over the Isen with great loss, and many perished at the crossing. At night fresh forces came over the river against their camp, for all Isengard had been emptied, and Saruman had armed the wild hillmen and herd-folk of Dunland beyond the rivers and loosed them upon the Rohirrim. The shield-wall was broken, and Erkenbrand of Westfold had drawn off those men he could gather towards his fastness in Helm's Deep, while the rest were scattered. The messenger's words carry the full weight of the alliance's fragility: "Tell him there is no hope ahead. He should return to Edoras before the wolves of Isengard come there." This is the moment when Rohan, Gondor's oldest ally, is itself on the verge of destruction, unable to fulfill its oath because its own realm is being overrun. Théoden, who had sat silent hidden from the man's sight behind his guards, then urges his horse forward and reveals himself: "Come, stand before me, Ceorl! I am here. The last host of the Eorlingas has ridden forth. It will not return without battle." The man's face lightens with joy and wonder, and he kneels, offering his notched sword to the king, crying "Command me, lord! And pardon me! I thought—" The scene captures the alliance's inner strength: even in defeat, the loyalty of the Rohirrim to their king and their cause remains unbroken, and the promise to ride to Gondor's aid, though delayed by Rohan's own peril, is not abandoned.
The Search for the Captured Hobbits
The alliance between Rohan and Gondor is also a bond of shared enemies and shared losses, as seen in the aftermath of the battle where the hobbits Meriadoc Brandybuck and Peregrin Took were captured. Aragorn, searching the battlefield near the river-bank, finds a broken mallorn-leaf of Lórien, golden in hue but now fading and turning brown, with small crumbs on it and a few more crumbs in the grass, along with pieces of cut cord lying nearby. Gimli then draws out of a tussock a short jagged blade, an orc-weapon with a carved handle shaped like a hideous head with squinting eyes and leering mouth, the haft snapped off beside it. Legolas reads the riddle with characteristic wit: a bound prisoner escapes both from the Orcs and from the surrounding horsemen, then stops in the open to cut his bonds with an orc-knife, and being pleased with his skill, sits down and quietly eats some waybread. "That at least is enough to show that he was a hobbit, without the mallorn-leaf," he concludes, adding that the prisoner must then have turned his arms into wings and flown away singing into the trees. The scene shows the three companions of the Fellowship — Aragorn of Gondor's royal line, Gimli the dwarf, and Legolas the elf — working together in the service of a quest that concerns both Rohan and Gondor, and it underscores how the fate of the hobbits, the smallest of the Free Peoples, is bound up with the great alliance of the western realms.
The Fall of the Dark Tower and the New Order
The alliance reaches its culmination after the destruction of the One Ring, when the old order of the West is restored and the relationship between Rohan and Gondor is transformed. Frodo Baggins, returning to the Shire, confronts a ruffian who boasts that Lotho will do what Sharkey says, and that if a Boss gives trouble, they can change him. Frodo replies with the full news of the war's outcome: "Your day is over, and all other ruffians'. The Dark Tower has fallen, and there is a King in Gondor. And Isengard has been destroyed, and your precious master is a beggar in the wilderness. I passed him on the road. The King's messengers will ride up the Greenway now, not bullies from Isengard." The ruffian mocks him, snapping his fingers in Frodo's face and dismissing the King's messengers, but Pippin, whose thoughts go back to the Field of Cormallen, casts back his cloak and flashes out his sword, the silver and sable of Gondor gleaming on him as he rides forward. The moment marks the final vindication of the alliance: Gondor has a King again, Isengard is destroyed, and the power that threatened both realms is broken. The King's messengers riding up the Greenway are the living symbol of the new order, in which Rohan and Gondor, no longer the last desperate defenders of the West, stand as the twin pillars of a restored and reunited kingdom under the crown of Aragorn.
