At daybreak on this day, Aragorn sets out to meet his appointed destiny on the Paths of the Dead, where he hopes to rally the ancient and cursed army to the cause of Isildur's heir, luring them with the promise of their freedom if they fight for him. The journey starts fraught--Eowyn, desperate with both love for him and desire for great deeds, falls upon her knees before him to beg leave to go along. He must refuse her,
"and only those who knew him well and were near to him saw the pain that he bore."
Tolkien then describes the long hours of a dreadful journey under the mountains of Dunharrow along the Dimholt Road in the company of the Dead--a journey that the Dunedain and their horses, the sons of Elrond, and Gimli and Legolas can bear only because of their love for Aragorn and the strength of his will. When they finally emerge the race is on for the Stone of Erech, which they, and the following Army of the Dead, must reach ere midnight. Along the route people flee and hide in stark terror of the King of the Dead. They reach the Stone, and here the Ranger gives way at last, irrevocably, to the King. Aragorn blows a silver horn made for the purpose, and Dead Army answers.
By the Stone of Erech, Aragorn speaks.
