Mormon 6

What happens now is almost beyond comprehension. All of the Nephites retreat and gather at the hill called Cumorah. Whether it's the one in New York or another one, we don't know. There's some argument that it could be in central Americal and Moroni's fleeing and travels took him far north to bury the plates that Joseph found. If there were many plates, that would make sense as it would be difficult for Moroni to get them all that distance. In one last battle to the end, Mormon is wounded and passed over for dead. 250,000 Nephite warriors our killed along with all the women and children except for 24 who survive and a few who dissent to the Lamanites. It's easily possible that 1 to 2 million are killed in this last battle. Mormon is left to look at the remains of his slain people and in anguish cries over their destruction and how a people who had once been so righteous and prosperous could sink to oblivion. The saddest thing of all is, it was their own decisions that brought them down.
