Coriantumr’s Ramah Tents are the encampment of Coriantumr’s army beside the hill Ramah. His army “did pitch their tents by the hill Ramah,” the same hill where Mormon later “did hide up the records unto the Lord, which were sacred” (Ether 15:11).
The opposing peoples spent “the space of four years gathering together the people” before the final battles (Ether 15:14). At night the exhausted armies “retired to their camps,” then took up “a howling and a lamentation for the loss of the slain of their people” until their cries rent the air (Ether 15:16).
