John Tolkien - The Return of the King

The third evil was the invasion of the Wainriders, which sapped the waning strength of Gondor in wars that lasted for almost a hundred years. The Wainriders were a people, or a confederacy of many peoples, that came from the East; but they were stronger and better armed than any that had appeared before. They journeyed in great wains, and their chieftains fought in chariots. Stirred up, as was afterwards seen, by the emissaries of Sauron, they made a sudden assault upon Gondor, and King Narmacil II was slain in battle with them beyond Anduin in 1856. The people of eastern and southern Rhovanion were enslaved; and the frontiers of Gondor were for that time withdrawn to the Anduin and the Emyn Muil. [At this time it is thought that the Ringwraiths re-entered Mordor.]

Calimehtar, son of Narmacil II, helped by a revolt in Rhovanion, avenged his father with a great victory over the Easterlings upon Dagorlad in 1899, and for a while the peril was averted. It was in the reign of Araphant in the North and of Ondoher son of Calimehtar in the South that the two kingdoms again took counsel together after long silence and estrangement. For at last they perceived that some single power and will was directing the assault from many quarters upon the survivors of Númenor. It was at that time that Arvedui heir of Araphant wedded Firiel daughter of Ondoher (1940). But neither kingdom was able to send help to the other; for Angmar renewed its attack upon Arthedain at the same time as the Wainriders reappeared in great force.

Many of the Wainriders now passed south of Mordor and made alliance with men of Khand and of Near Harad; and in this great assault from north and south, Gondor came near to destruction. In 1944 King Ondoher and both his sons, Artamir and Faramir, fell in battle north of the Morannon, and the enemy poured into Ithilien. But Eärnil, Captain of the Southern Army, won a great victory in South Ithilien and destroyed the army of Harad that had crossed the River Poros. Hastening north, he gathered to him all that he could of the retreating Northern Army and came up against the main camp of the Wainriders, while they were feasting and revelling, believing that Gondor was overthrown and that nothing remained but to take the spoil. Eärnil stormed the camp and set fire to the wains, and drove the enemy in a great rout out of Ithilien. A great part of those who fled before him perished in the Dead Marshes.

'On the death of Ondoher and his sons, Arvedui of the North-kingdom claimed the crown of Gondor, as the direct descendant of Isildur, and as the husband of Firiel, only surviving child of Ondoher. The claim was rejected. In this Pelendur, the Steward of King Ondoher, played the chief part.

'The Council of Gondor answered: "The crown and royalty of Gondor belongs solely to the heirs of Meneldil, son of Anárion, to whom Isildur relinquished this realm. In Gondor this heritage is reckoned through the sons only; and we have not heard that the law is otherwise in Arnor."

'To this Arvedui replied: "Elendil had two sons, of whom Isildur was the elder and the heir of his father. We have heard that the name of Elendil stands to this day at the head of the line of the Kings of Gondor, since he was accounted the high king of all the lands of the Dunedain. While Elendil still lived, the conjoint rule in the South was committed to his sons; but when Elendil fell, Isildur departed to take up the high kingship of his father, and committed the rule in the South in like manner to the son of his brother. He did not relinquish his royalty in Gondor, nor intend that the realm of Elendil should be divided for ever.

'"Moreover, in Númenor of old the sceptre descended to the eldest child of the king, whether man or woman. It is true that the law has not been observed in the lands of exile ever troubled by war; but such was the law of our people, to which we now refer, seeing that the sons of Ondoher died childless." 33 33 That law was made in Númenor (as we have learned from the King) when Tar-Aldarion, the sixth king, left only one child, a daughter. She became the first Ruling Queen, Tar-Ancalime. But the law was otherwise before her time. Tar-Elendil, the fourth king, was succeeded by his son Tar-Meneldur, though his daughter Silmarien was the elder. It was, however, from Silmarien that Elendil was descended'.

To this Gondor made no answer. The crown was claimed by Eärnil, the victorious captain; and it was granted to him with the approval of all the Dunedain in Gondor, since he was of the royal house. He was the son of Siriondil, son of Calimmacil, son of Arciryas brother of Narmacil II. Arvedui did not press his claim; for he had neither the power nor the will to oppose the choice of the Dunedain of Gondor; yet the claim was never forgotten by his descendants even when their kingship had passed away. For the time was now drawing near when the North-kingdom would come to an end.

'Arvedui was indeed the last king, as his name signifies. It is said that this name was given to him at his birth by Malbeth the Seer, who said to his father: " Arvedui you shall call him, for he will be the last in Arthedain. Though a choice will come to the Dunedain, and if they take the one that seems less hopeful, then your son will change his name and become king of a great realm. If not, then much sorrow and many lives of men shall pass, until the Dunedain arise and are united again."

'In Gondor also one king only followed Eärnil. It may be that if the crown and the sceptre had been united, then the kingship would have been maintained and much evil averted. But Eärnil was a wise man, and not arrogant, even if, as to most men in Gondor, the realm in Arthedain seemed a small thing, for all the lineage of its lords.

'He sent messages to Arvedui announcing that he received the crown of Gondor, according to the laws and the needs of the South-kingdom, "but I do not forget the loyalty of Arnor, nor deny our kinship, nor wish that the realms of Elendil should be estranged. I will send to your aid when you have need, so far as I am able."

'It was, however, long before Eärnil felt himself sufficiently secure to do as he promised. King Araphant continued with dwindling strength to hold off the assaults of Angmar, and Arvedui when he succeeded did likewise; but at last in the autumn of 1973 messages came to Gondor that Arthedain was in great straits, and that the Witch-king was preparing a last stroke against it. Then Eärnil sent his son Earnur north with a fleet, as swiftly as he could, and with as great strength as he could spare. Too late. Before Earnur reached the havens of Lindon, the Witch-king had conquered Arthedain and Arvedui had perished.

'But when Earnur came to the Grey Havens there was joy and great wonder among both Elves and Men. So great in draught and so many were his ships that they could scarcely find harbourage, though both the Harlond and the Forlond also were filled; and from them descended an army of power, with munition and provision for a war of great kings. Or so it seemed to the people of the North, though this was but a small sending-force of the whole might of Gondor. Most of all, the horses were praised, for many of them came from the Vales of Anduin, and with them.were riders tall and fair, and proud princes of Rhovanion.

Then Cirdan summoned all who would come to him, from Lindon or Arnor, and when all was ready the host crossed the Lune and marched norm to challenge the Witch-king of Angmar. He was now dwelling, it is said, in Fornost, which he had filled with evil folk, usurping the house and rule of the kings. In his pride he did not await the onset of his enemies in his stronghold, but went out to meet them, thinking to sweep them, as others before, into the Lune.

'But the Host of the West came down on him out of the Hills of Evendim, and were was a great battle on the plain between Nenuial and the North Downs. The forces of Angmar were already giving way and retreating towards Fornost when the main body of the horsemen that had passed round the hills Came down from the north and scattered them in a great rout. Then the Witch-king, with all that he could gather from the wreck, fled northwards, seeking his own land of Angmar. Before he could gain the shelter of Carn Dum the cavalry of Gondor overtook him with Earnur riding at their head. At the same time a force under Glorfindel the Elf-lord came up out of Rivendell. Then so utterly was Angmar defeated that not a man nor an orc of that realm remained west of the Mountains.
