Things of Middle-earth
Host of the West
the Men of the West
the army of the West
The alliance of armies from Rohan and Gondor plus various other individuals, gathered under Gandalf's and Aragorn's command to fight the Battle of the Morannon at the end of the War of the Ring.
This then was the end of the debate of the lords: that they should set forth on the second morning from that day with seven thousands, if these might be found; and the great part of this force should be on foot, because of the evil lands into which they would go. Aragorn should find some two thousands of those that he had gathered to him in the South; but Imrahil should find three and a half thousands; and Éomer five hundreds of the Rohirrim who were unhorsed but themselves warworthy, and he himself should lead five hundreds of his best Riders on horse; and another company of five hundred horse there should be, among which should ride the sons of Elrond with the Dúnedain and the knights of Dol Amroth: all told six thousand foot and a thousand horse.

Upon the one hill [Aragorn] stood with Gandalf, and there fair and desperate was raised the banner of the Tree and Stars. Upon the other hill hard by stood the banners of Rohan and Dol Amroth.... And about each hill a ring was made facing all ways, bristling with spear and sword. But in the front towards Mordor where the first bitter assault would come there stood the sons of Elrond on the left with the Dúnedain about them, and on the right the Prince Imrahil with the men of Dol Amroth tall and fair, and picked men of the Tower of Guard.
