Description: "Beyond its stony course they saw a beaten path that wound its way under the feet of the westward cliffs. Had they known, they could have reached it quicker, for it was a track that left the main Morgul-road at the western bridge-end and went down by a long stair cut in the rock to the valley’s bottom. It was used by patrols or by messengers going swiftly to lesser posts and strongholds north-away, between Cirith Ungol and the narrows of Isenmouthe, the iron jaws of Carach Angren...
"The trough between the mountains and the Morgai had steadily dwindled as it climbed upwards, and the inner ridge was now no more than a shelf in the steep faces of the Ephel Dúath; but to the east it fell as sheerly as ever down into Gorgoroth. Ahead the water-course came to an end in broken steps of rock; for out from the main range there sprang a high barren spur, thrusting eastward like a wall. To meet it there stretched out from the grey and misty northern range of Ered Lithui a long jutting arm; and between the ends there was a narrow gap: Carach Angren, the Isenmouthe, beyond which lay the deep dale of Udûn. In that dale behind the Morannon were the tunnels and deep armouries that the servants of Ephel Dúathhad made for the defence of the Black Gate of their land; and there now their Lord was gathering in haste great forces to meet the onslaught of the Captains of the West. Upon the out-thrust spurs forts and towers were built, and watch-fires burned; and all across the gap an earth-wall had been raised, and a deep trench delved that could be crossed only by a single bridge.
"A few miles north, high up in the angle where the western spur branched away from the main range, stood the old castle of Durthang, now one of the many orc-holds that clustered about the dale of Udûn. A road, already visible in the growing light, came winding down from it, until only a mile or two from where the hobbits lay it turned east and ran along a shelf cut in the side of the spur, and so went down into the plain, and on to the Isenmouthe.
"To the hobbits as they looked out it seemed that all their journey north had been useless. The plain to their right was dim and smoky, and they could see there neither camps nor troops moving; but all that region was under the vigilance of the forts of Carach Angren.
