Elrond retreats from Eriador
Event Type: Military/Strategic
Age: 2nd Age - Rings
"In black anger he turned back to battle; and bearing as a banner Celebrimbor's body hung upon a pole, shot through with Orc-arrows, he turned upon the forces of Elrond. Elrond had gathered such few of the Elves of Eregion as had escaped, but he had no force to withstand the onset. He would indeed have been overwhelmed had not Sauron's force been attacked in the rear; for Durin sent out a force of Dwarves from Khazad-dûm, and with them came elves of Lórinand led by Amroth. Elrond was able to extricate himself, but he was forced away northwards..."
"Sauron withdrew the pursuit of Elrond and turned upon the Dwarves and the Elves of Lórinand, whom he drove back; but the Gates of Moria were shut, and he could not enter."
