The Lord of the Rings

Isengard. It was soon known that Wulf was their leader. They 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, Háma 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.
    ‘One night men heard the horn blowing, but Helm did not return. In themorning there came a sun-gleam, the first for long days, and they saw a white figure standing still on the Dike, alone, for none of the Dunlendings dared come near. There stood Helm, dead as a stone, but his knees were unbent. Yet men said that the horn was still heard at times in the Deep and the wraith of Helm would walk among the foes of Rohan and kill men with fear.
    ‘Soon after the winter broke. Then Fréaláf, son of Hild, Helm’s sister, came down out of Dunharrow, to which many had fled; and with a small company of desperate men he surprised Wulf in Meduseld and slew him, and regained Edoras. There were great floods after the snows, and the vale of Entwash became a vast fen. The Eastern invaders perished or withdrew; and there came help at last from Gondor, by the roads both east and west of the mountains. Before the year (2759) was ended the Dunlendings were driven out, even from Isengard; and then Fréaláf became king.
    ‘Helm was brought from the Hornburg and laid in the ninth mound. Ever after the white
simbelmynë
grew there most thickly, so that the mound seemed to be snow-clad. When Fréaláf died a new line of mounds was begun.’
    The Rohirrim were grievously reduced by war and dearth and loss of cattle and horses; and it was well that no great danger threatened them again for many years, for it was not until the time of King Folcwine that they recovered their former strength.
    It was at the crowning of Fréaláf that Saruman appeared, bringing gifts, and speaking great praise of the valour of the Rohirrim. All thought him a welcome guest. Soon after he took up his abode in Isengard. For this, Beren, Steward of Gondor, gave him leave, for Gondor still claimed Isengard as a fortress of its realm, and not part of Rohan. Beren also gave into Saruman’s keeping the keys of Orthanc. That tower no enemy had been able to harm or to enter.
    In this way Saruman began to behave as a lord of Men; for at first he held Isengard as a lieutenant of the Steward and warden of the tower. But éFrealaf was as glad as Beren to have this so, and to know that Isengard was in the hands of a strong friend. A friend he long seemed, and maybe in the beginning he was one in truth. Though afterwards there was little doubt in men’s minds that Saruman went to Isengard in hope to find the Stone still there, and with the purpose of building up a power of his own. Certainly after the last White Council (2953) his designs towards Rohan, though he hid them, were evil. He then took Isengard for his own and began to make it a place of guarded strength and fear, as though to rival the Barad-dûr. His friends and servants he drew then from all who hated Gondor and Rohan,
