The Siege of Gondor
The Siege of Gondor represents the Dark Lord Sauron's primary military stroke against the West, a meticulously prepared assault designed to crush the last great bastion of Men before his dominion could be absolute. The attack was launched in concert with a massive diversionary campaign: the Corsairs of Umbar sailed up the Anduin to threaten the southern fiefs, while a separate army crossed the River from the north-east after capturing Cair Andros. This strategy aimed to isolate Minas Tirith and prevent relief from reaching it, leaving the city to be overwhelmed by the main host that issued from Minas Morgul under the command of the Witch-king, the Lord of the Nazgûl.
The Breaching of the Outer Defenses
The siege began in earnest after the retreat of Faramir's forces from Osgiliath. The enemy swiftly overran the Rammas Echor, the outer wall of the Pelennor, using fire and blasting devices to create breaches. The retreating Gondorian soldiers were harried by the Nazgûl, who swooped down from the sky, spreading terror. A desperate sortie led by Gandalf and the knights of Dol Amroth managed to rescue Faramir, who had been struck down by a poisoned dart from a Haradrim archer, but the city's outer ring was lost. The host of Mordor then encircled Minas Tirith, digging vast trenches filled with fire and setting up great siege engines, including catapults that hurled missiles over the high, unbreachable outer wall. Among these projectiles were the severed heads of the slain, flung into the city to spread despair and to remind the defenders of their fallen kin.
The Assault on the Gate
The main assault was concentrated against the Great Gate, the perceived weakest point in the city's otherwise impregnable stonework. The Witch-king brought forth Grond, a huge battering-ram shaped like a ravening wolf, forged in the dark smithies of Mordor and inscribed with ruinous spells. Dragged by great beasts and protected by mountain-trolls, Grond was hurled against the Gate. The first two blows were withstood, but on the third stroke, the Witch-king himself rose in his stirrups and cried aloud in a forgotten tongue, a word of power and terror. A searing flash of lightning burst the doors asunder, and the Lord of the Nazgûl rode through the archway into the city, a vast black shape of menace and despair before whom all fled.
The Madness of Denethor and the Fall of the City's Hope
Within the city, the siege was paralleled by a spiritual and psychological collapse. Steward Denethor, having long used the palantír of Minas Tirith to spy on Sauron's movements, had been deceived and driven to despair by the visions of Mordor's overwhelming might. The wounding of his son Faramir, whom he loved more than his other son Boromir, broke his will entirely. Believing all was lost, Denethor resolved to burn himself and his son on a pyre in the Houses of the Dead, declaring that the West had failed. Gandalf, who had been commanding the defense, was forced to abandon the walls to confront this madness. He rescued Faramir from the flames, but Denethor, clutching the palantír, set himself alight and perished in the fire. This act of despair removed the city's leader at its most critical hour, leaving the defense in the hands of Gandalf and Prince Imrahil.
The Climax and the Turning Tide
As the Witch-king entered the breached Gate, Gandalf alone confronted him on Shadowfax, barring the way. The Lord of the Nazgûl mocked the wizard, declaring that this was his hour and that death was upon him. At that very moment, however, the horns of the Rohirrim were heard, signaling the arrival of King Théoden's cavalry. The Witch-king was forced to withdraw from the Gate to meet this new threat, turning the tide of the siege. The subsequent Battle of the Pelennor Fields saw the destruction of the Witch-king by Éowyn and Merry, the death of Théoden, and the eventual relief of the city by Aragorn's forces arriving in the captured ships of the Corsairs. The siege was broken, but the victory was bought at a grievous cost, leaving the city scarred and its leadership in ruins.
