John Tolkien - The Return of the King

'Thus he came to the battle of the Field of Celebrant, for that was the name of the green land that lay between Silverlode and Limlight. There the northern army of Gondor was in peril. Defeated in the Wold and cut off from the south, it had been driven across the Limlight, and was then suddenly assailed by the Orc-host that pressed it towards the Anduin. All hope was lost when, unlooked for, the Riders came out of the North and broke upon the rear of the enemy. Then the fortunes of battle were reversed, and the enemy was driven with slaughter over Limlight. Eorl, led his men in pursuit, and so great was the fear that went before horsemen of the North that the invaders of the Wold were also thrown into panic, and the Riders hunted them over the plains of Calenardhon.'

The people of that region had become few since the Plague, and most of those that remained had been slaughtered by the savage Easterlings. Cirion, therefore, in reward for his aid, gave Calenardhon between Anduin and Isen to Eorl and his people; and they sent north for their wives and children and their goods and sealed in that land. They named it anew the Mark of the Riders, and they called themselves the Eorlingas; but in Gondor their land was called Rohan, and its people the Rohirrim (that is, the Horse-lords). Thus Eorl became the first King of the Mark, and he chose for his dwelling a green hill before the feet of the White Mountains that we're the south-wall of his land. There the Rohirrim lived afterwards as free men under their own kings and laws, but in perpetual alliance with Gondor.

'Many lords and warriors, and many fair and valiant women, are named in the songs of Rohan that still remember the North. Frumgar, they say, was the name of the chieftain who led his people to Éothéod. Of his son, Fram, they tell that he slew Scatha, the great dragon of Ered Mithrin, and the land had peace from the long-worms afterwards. Thus Fram won great wealth, but was at feud with the Dwarves, who claimed the hoard of Scatha. Fram would not yield them a penny, and sent to them instead the teeth of Scatha made into a necklace, saying: "Jewels such as these you will not match in your treasuries, for they are hard to come by." Some say that the Dwarves slew Fram for this insult. There was no great love between Éothéod and the Dwarves.

'Léod was the name of Eorl's father. He was a tamer of wild horses; for there were many at that time in the land. He captured a white foal and it grew quickly to a horse strong, and fair, and proud. No man could tame it. When Léod dared to mount it, it bore him away, and at last threw him, and Léod's head struck a rock, and so he died. He was then only two and forty years old, and his son a youth of sixteen.

'Eorl vowed that he would avenge his father. He hunted long for the horse, and at last he caught sight of him; and his companions expected that he would try to come within bowshot and kill him. But when they drew near, Eorl stood up and called in a loud voice: "Come hither, Mansbane, and get a new name!" To their wonder the horse looked towards Eorl, and came and stood before him, and Eorl said: "Felaróf I name you. You loved your freedom, and I do not blame you for that. But now you owe me a great weregild, and you shall surrender your freedom to me until your life's end."

'Then Eorl mounted him, and Felaróf submitted; and Eorl rode him home without bit or bridle; and he rode him in like fashion ever after. The horse understood all that men said, though he would allow no man but Eorl to mount him. It was upon Felaróf that Eorl rode to the Field of Celebrant; for that horse proved as long lived as Men, and so were his descendants. These were the mearas , who would bear no one but the King of the Mark or his sons, until the time of Shadowfax. Men said of them that Bema (whom the Eldar call Orome) must have brought their sire from West over Sea.

'Of the Kings of the Mark between Eorl and Théoden most is said of Helm Hammerhand. He was a grim man of great strength. There was at that time a man named Freca, who claimed descent from King Freawine, though he had, men said, much Dunlendish blood, and was dark-haired. He grew rich and powerful, having wide lands on either side of the Adorn. 37 37 It flows into Isen from the west of Ered Nimrais. Near its source he made himself a stronghold and paid little heed to the king. Helm mistrusted him, but called him to his councils; and he came when it pleased him.

'To one of these councils Freca rode with many men, and he asked the hand of Helm's daughter for his son Wulf. But Helm said: "You have grown big since you were last here; but it is mostly fat, I guess"; and men laughed at that, for Freca was wide in the belt.

'Then Freca fell in a rage and reviled the king, and said this at the last: "Old kings that refuse a proffered staff may fall on their knees." Helm answered: "Come! The marriage of your son is a trifle. Let Helm and Freca deal with it later. Meanwhile the king and his council have matters of moment to consider."

'When the council was over, Helm stood up and laid his great hand on Freca's shoulder, saying: "The king does not permit brawls in his house, but men are freer outside"; and he forced Freca to walk before him out from Edoras into the field. To Freca's men that came up he said: "Be off! We need no hearers. We are going to speak of a private matter alone. Go and talk to my men!" And they looked and saw that the king's men and his friends far outnumbered them, and they drew back.

'"Now, Dunlending," said the king, "you have only Helm to deal with, alone and unarmed. But you have said much already, and it is my turn to speak. Freca, your folly has grown with your belly. You talk of a staff! If Helm dislikes a crooked staff that is thrust on him, he breaks it. So!" With that he smote Freca such a blow with his fist that he fell back stunned, and died soon after.

'Helm then proclaimed Freca's son and near kin the king's enemies; and they fled, for at once Helm sent many men riding to the west marches.'

Four years later (2758) great troubles came to Rohan, and no help could be sent from Gondor, for three fleets of the Corsairs attacked it and there was war on all its coasts. At the same time Rohan was again invaded from the East, and the Dunlendings seeing their chance came over the Isen and down from Isengard. It was soon known that Wulf was their leader. The were in great force, for they were joined by enemies of Gondor that landed in the mouths of Lefnui and Isen.

The Rohirrim were defeated and their land was overrun; and those who were not slain or enslaved fled to the dales of the mountains. Helm was driven back with great loss from the Crossings of Isen and took refuge in the Hornburg and the ravine behind (which was after known as Helm's Deep). There he was besieged. Wulf took Edoras and sat in Meduseld and called himself king. There Haleth Helm's son fell, last of all, defending the doors.

'Soon afterwards the Long Winter began, and Rohan lay under snow for nearly five months (November to March, 2758-9). Both the Rohirrim and their foes suffered grievously in the cold, and in the dearth that lasted longer. In Helm's Deep there was a great hunger after Yule; and being in despair, against the king's counsel, Hama his younger son led men out on a sortie and foray, but they were lost in the snow. Helm grew fierce and gaunt for famine and grief; and the dread of him alone was worth many men in the defence of the Burg. He would go out by himself, clad in white, and stalk like a snow-troll into the camps of his enemies, and slay many men with his hands. It was believed that if he bore no weapon no weapon would bite on him. The Dunlendings said that if he could find no food he ate men. That tale lasted long in Dunland. Helm had a great horn, and soon it was marked that before he sallied forth he would blow a blast upon it that echoed in the Deep; and then so great a fear fell on his enemies that instead of gathering to take him or kill him they fled away down the Coomb.
