Of the six men who rode north, only one: Borondir, survived and brought his Steward's request for aid to the Éothéod. Fifteen days had he riden and barely escaped the arrows of an ambush close by Dol Guldur. His companion had not his luck nor his horse the speed of Borondir's and he was slain. Borondir's trial was not over though and he had many times had to ride miles out of his way to avoid those who hunted for him. When he reached Framsburg, Borondir had been without food for two days and was nigh unto collapse. But he spoke the Steward's words to Eorl and brought forth a token-a stone carved with "R ND R" and three stars proving he was the Arandur's man.

On that twenty-fifth day of Súlimë, Eorl heard the words and fell silent. But he did not tarry long. Eorl rose and spoke thus: "I will come. If the Mundburg falls, whither shall we flee from the Darkness." And he took the hand of Borondir to seal his oath. Eorl at once summoned his counselors so that provisions might be made for the éohere to ride south to Gondor while yet keeping safe the homes and people of the Éothéod. Thus it was decided to take 7,000 fully armed riders and several hundred horse archers. Only a few hundreds of men--those too old or too young to be a part of such a ride were left to guard the Éothéod. For Eorl saw that he needs must bring a great host or none at all as the Balchoth were so many. And on the day they set out, Borondir rode at the right hand of Eorl.

So great was the fear and awe of the host that during the journey to the Vales of Anduin, all who saw it fled before it. When they came nigh to Dol Guldur, Eorl turned them west to avoid the shadow and cloud that poured from the tower and they turned to ride in sight of Anduin. As they went, many found their gaze drawn across the river-not knowing if it was in hope or fear-to see if they might catch sight of the land they named the Dwimordene, the "magic wood" that their grandfathers had told them shone with a golden light. What they saw was a golden mist over the Dwimordene that crossed Anduin like a shimmering fog and covered the land before them. Many quailed at the idea of entering such an enchantment but Eorl cried out to them: "Ride on! There is no other way to take. After so long a road shall we be held back from battle by a river mist?" And the men's spirits rose as they followed him.

As the éohere went forward, they saw that the mists of Dwimordene were driving back the darkness of Dol Guldur and they took heart as they entered the golden cloud. Within the light was such that they cast no shadows and were walking within white walls of fog. Borondir bespoke that the Lady of the Golden Wood favored them but Eorl replied that "I will trust the wisdom of Felaróf. He scents no evil. His heart is high, and his weariness is healed: he strains to be given his head. So be it! For never have I had more need of secrecy and speed."

And the host rode silently through the arching mists as if they were but newly set out upon their long journey. The rest of that day and the next they rode within the white fogs but with the morn of the third day the mists faded away and they saw that they had come within sight of the Undeeps. The day was the fifteenth day of Víressë and they had come almost 600 miles in nine days to aid of the men of Gondor.

Gondor's northern army had been defeated by the Balchoth in the Wold of Calenardhon and driven back across the River Limlight. There they were trapped between that river and Anduin. It seemed that the final blow had been given when orcs out of Moria fell upon them. Eorl lead the Éothéod to attack the Balchoth from the rear and the Balchoth were driven with great loss of life back over the Limlight. The Éothéod then pursued them across the plains of Calenardhon singing with the joy of battle as they destroyed what was left of the invaders.
