Battle of the Green Fork

The Battle of the Green Fork was a deliberate feint orchestrated by Lord Tywin Lannister to draw the young Stark commander into a trap, while the true northern strike force slipped away to win a decisive victory in the Whispering Wood. Fought at dawn on a rolling plain beside the kingsroad, the engagement pitted Tywin's massive, disciplined army against a smaller northern force under Roose Bolton. Though a tactical Lannister victory, the battle was a strategic success for the north, because the northern army Tywin crushed was only a diversion; Robb Stark and his cavalry were already crossing the Green Fork far to the north, racing toward Riverrun and the unsuspecting Jaime Lannister.

Tywin's Plan and the Feigned Rout

Lord Tywin Lannister had anticipated the northern advance and prepared a sophisticated trap. He placed his least reliable troops—freeriders, sellswords, and the undisciplined mountain clansmen under his son Tyrion—on the left wing, expecting them to break under the northern assault. His hope was that the young and inexperienced Robb Stark, seeing the Lannister left collapse, would commit his forces recklessly, plunging into the gap. Once the northerners were fully engaged, Ser Kevan Lannister's pikemen would wheel and take them in the flank, driving them into the river while Tywin himself brought up the reserve to complete the destruction. Tyrion, who had been kept ignorant of the plan, was placed in the vanguard under Ser Gregor Clegane, leading his three hundred mountain clansmen—Stone Crows, Black Ears, Moon Brothers, and Burned Men—as part of the disposable left. When Tyrion later confronted his father about the deception, Lord Tywin replied that a feigned rout was less convincing if the commander knew it was feigned, and that he was not inclined to trust his plans to a man who consorted with sellswords and savages.

The Northern Advance and the Clash

The northern host, commanded by Roose Bolton, marched south from the Twins and formed up in battle array less than a mile from the Lannister camp. Their banners included the bull moose of the Hornwoods, the Karstark sunburst, Lord Cerwyn's battle-axe, the mailed fist of the Glovers, and the twin towers of Frey—proof that Lord Walder Frey had indeed stirred himself. The white direwolf of House Stark flew everywhere. As the northerners advanced, a vast flight of arrows from the Lannister archers flanking the kingsroad fell on them like hail, turning shouts to screams as men stumbled and went down. Despite the casualties, the northerners broke into a run, and the Lannister trumpets blared the charge. Ser Gregor Clegane led the van, a wedge of armored veterans, straight into a crescent of Karstark spearmen. The Mountain's stallion was killed under him, but he rose untouched and laid about him with his two-handed greatsword. Shagga son of Dolf and the Stone Crows burst through the gap before the shields could close, and the hedgehog of spears began to crumble.

Tyrion in the Van

Tyrion Lannister, leading his clansmen along the riverbank as ordered, found himself in the thick of the fighting. He saw a Burned Man ride past with a spear through his belly, and charged a tall northern swordsman who had lost his helm. The man was quicker and stronger, and Tyrion's shield was shattered by a blow. His destrier saved him by biting the man's cheek to the bone, and Tyrion buried his axe in the man's head. A second knight, shouting "For Eddard and Winterfell," rode him down with a morningstar, shattering Tyrion's elbow and knocking him from his horse. As the knight demanded his surrender, Tyrion drove his head into the horse's belly, disemboweling the animal with the spike of his helm. The knight's leg was trapped under the fallen horse, and he yielded. Dazed and wounded, Tyrion knelt and lifted the man's sword, accepting his surrender.

The Rout and the Revelation

The Lannister left, as Tywin had predicted, collapsed under the northern assault, but the northerners did not plunge recklessly into the gap. Instead, they pressed their advantage methodically. Ser Kevan brought up the center in support, his pikemen pushing the northerners back against the hills. Then Lord Tywin committed his reserve, five thousand fresh troops, half mounted and half foot, sweeping up along the river. The remnants of the Stark lines shattered like glass beneath the hammer of their charge. The Lannisters took several northern commanders prisoner, including Lord Cerwyn, Ser Wylis Manderly, Harrion Karstark, and four Freys. Lord Hornwood was killed. Roose Bolton escaped. But when Ser Addam Marbrand reported the victory, he delivered the news that changed everything: the Stark boy was not with them. Robb Stark had crossed at the Twins with the great part of his horse, riding hard for Riverrun. The boy Tywin had dismissed as a green fool had outmaneuvered the most feared commander in the Seven Kingdoms.

Aftermath and Consequences

Though a tactical victory for the Lannisters, the Battle of the Green Fork was a strategic catastrophe. Tywin's army had won the field but lost the war in a single stroke. While he was crushing a diversionary force, Robb Stark had slipped past him, joined with the river lords, and trapped Jaime Lannister's army between the fords of the Trident and the walls of Riverrun. The battle also revealed the deep fractures within the Lannister command. Tyrion, wounded and bitter, confronted his father afterward, accusing him of placing him in the van without warning and expecting him to be butchered. Lord Tywin admitted the feigned rout but showed no remorse, saying he was not inclined to trust his plans to a man who consorted with sellswords and savages. The victory was hollow, and Tywin knew it. He ordered the army to march for Harrenhal, unleashing Ser Gregor Clegane, Vargo Hoat, and Ser Amory Lorch to burn the riverlands from the Gods Eye to the Red Fork, a scorched-earth campaign meant to draw Robb Stark into a decisive battle on ground of Lannister choosing.
