Unfinished Tales - J. R. R. Tolkien [162]
But in the earlier days, at the time of the first explorations of the Númenóreans, the situation was quite different. Minhiriath and Enedwaith were occupied by vast and almost continuous forests, except in the central region of the Great Fens. The changes that followed were largely due to the operations of Tar-Aldarion, the Mariner-king, who formed a friendship and alliance with Gil-galad. Aldarion had a great hunger for timber, desiring to make Númenor into a great naval power; his felling of trees in Númenor had caused great dissensions. In voyages down the coasts he saw with wonder the great forests, and he chose the estuary of the Gwathló for the site of a new haven entirely under Númenórean control (Gondor of course did not yet exist). There he began great works, that continued to be extended after his days. This entry into Eriador later proved of great importance in the war against Sauron (Second Age 1693– 1701); but it was in origin a timber-port and ship-building harbour. The native people were fairly numerous and warlike, but they were forest-dwellers, scattered communities without central leadership. They were in awe of the Númenóreans, but they did not become hostile until the tree-felling became devastating. Then they attacked and ambushed the Númenóreans when they could, and the Númenóreans treated them as enemies, and became ruthless in their fellings, giving no thought to husbandry or replanting. The fellings had at first been along both banks of the Gwathló, and timber had been floated down to the haven (Lond Daer); but now the Númenóreans drove great tracks and roads into the forests northwards and southwards from the Gwathló, and the native folk that survived fled from Minhiriath into the dark woods of the great Cape of Eryn Vorn, south of the mouth of the Baranduin, which they dared not cross, even if they could, for fear of the Elvenfolk. From Enedwaith they took refuge in the eastern mountains where afterwards was Dunland; they did not cross the Isen nor take refuge in the great promontory between Isen and Lefnui that formed the north arm of the Bay of Belfalas [Ras Morthil or Andrast: see p. 276, note 6], because of the ‘Púkel-men’.... [For the continuation of this passage see p. 495.]
The devastation wrought by the Númenóreans was incalculable. For long years these lands were their chief source of timber, not only for their ship-yards at Lond Daer and elsewhere, but also for Númenor itself. Ship-loads innumerable passed west over the sea. The denuding of the lands was increased during the war in Eriador; for the exiled natives welcomed Sauron and hoped for his victory over the Men of the Sea. Sauron knew of the importance to his enemies of the Great Haven and its ship-yards, and he used these haters of Númenor as spies and guides for his raiders. He had not enough force to spare for any assault upon the forts at the Haven or along the banks of the Gwathló, but his raiders made much havoc on the fringe of the forests, setting fire in the woods and burning many of the great wood-stores of the Númenóreans.
When Sauron was at last defeated and driven east out of Eriador most of the old forests had been destroyed. The Gwathló flowed through a land that was far and wide on either bank a desert, treeless but untilled. That was not so when it first received its name from the hardy explorers of Tar-Aldarion’s ship who ventured to pass up the river in small boats. As soon as the seaward region of salt airs and great winds was passed the forest drew down to the river-banks, and wide though the waters were the huge trees cast great shadows on the river, under which the boats of the adventurers crept silently up into the unknown land. So the first name they gave to it was ‘River of Shadow’, Gwath-hîr, Gwathir. But later they penetrated northward as far as the beginning of the great fenlands; though it was still long before they had the need or sufficient
