Mormon 6

 
1 And now I finish my record concerning the destruction of my people, the Nephites. And it came to pass that we did march forth before the Lamanites.
1
2 And I, Mormon, wrote an epistle unto the king of the Lamanites, and desired of him that he would grant unto us that we might gather together our people unto the land of Cumorah, by a hill which was called Cumorah, and there we could give them battle.
2
3 And it came to pass that the king of the Lamanites did grant unto me the thing which I desired.
3
4 And it came to pass that we did march forth to the land of Cumorah, and we did pitch our tents around about the hill Cumorah; and it was in a land of many waters, rivers, and fountains; and here we had hope to gain advantage over the Lamanites.
4
5 And when three hundred and eighty and four years had passed away, we had gathered in all the remainder of our people unto the land of Cumorah.
5
6 And it came to pass that when we had gathered in all our people in one to the land of Cumorah, behold I, Mormon, began to be old; and knowing it to be the last struggle of my people, and having been commanded of the Lord that I should not suffer the records which had been handed down by our fathers, which were sacred, to fall into the hands of the Lamanites, (for the Lamanites would destroy them) therefore I made this record out of the plates of Nephi, and hid up in the hill Cumorah all the records which had been entrusted to me by the hand of the Lord, save it were these few plates which I gave unto my son Moroni.
6
7 And it came to pass that my people, with their wives and their children, did now behold the armies of the Lamanites marching towards them; and with that awful fear of death which fills the breasts of all the wicked, did they await to receive them.
7
8 And it came to pass that they came to battle against us, and every soul was filled with terror because of the greatness of their numbers.
8
9 And it came to pass that they did fall upon my people with the sword, and with the bow, and with the arrow, and with the ax, and with all manner of weapons of war.

The only pre-Columbian weapon I can find that was similar to a sword was the macuahuitl which was made with a plank of wood similar in shape to a cricket bat with obsidian blades mounted on the edges. It is similar enough to a sword that it is often referred to as the Aztec sword.

However, the macuahuitl does not seem to fit the Book of Mormon time frame. “Some groups of Central Mexico, principally in the transition between the Early and the Late Post-Classic, probably developed this weapon” (emphasis added, Dr. Marco Antonio Cervera Obregón, “The macuahuitl: an innovative weapon of the Late Post-Classic in Mesoamerica”, Arms & Armour, Vol.3, Nov. 2, 2006, p. 146, article from a research journal). The Post-Classic period is between 900 CE and the Spanish conquest.

Mormon 6:10-15

I count 23 with their 10,000 that were killed in this horrific battle. In one place, 230,000 are killed on one side, perhaps 10s of thousands of Lamanites could be presumed killed in this battle too. Yet there is no evidence whatsoever of this battle at the hill Cumorah or anywhere else in the Americas.

11 And when they had gone through and hewn down all my people save it were twenty and four of us, (among whom was my son Moroni) and we having survived the dead of our people, did behold on the morrow, when the Lamanites had returned unto their camps, from the top of the hill Cumorah, the ten thousand of my people who were hewn down, being led in the front by me.

14 And Lamah had fallen with his ten thousand; and Gilgal had fallen with his ten thousand; and Limhah had fallen with his ten thousand; and Jeneum had fallen with his ten thousand; and Cumenihah, and Moronihah, and Antionum, and Shiblom, and Shem, and Josh, had fallen with their ten thousand each.

15 And it came to pass that there were ten more who did fall by the sword, with their ten thousand each; yea, even all my people, save it were those twenty and four who were with me, and also a few who had escaped into the south countries, and a few who had deserted over unto the Lamanites, had fallen; and their flesh, and bones, and blood lay upon the face of the earth, being left by the hands of those who slew them to molder upon the land, and to crumble and to return to their mother earth.

16 And my soul was rent with anguish, because of the slain of my people, and I cried:

17 O ye fair ones, how could ye have departed from the ways of the Lord! O ye fair ones, how could ye have rejected that Jesus, who stood with open arms to receive you!

Mormon calls his people the Nephites the 'fair ones'.

Some apologists claim that the lamanite's curse of dark skin wasn't literally their skin made dark. If that was true, why would mormon make this distinction that his people are 'fair ones', and lament the fact that his 'fair ones' had been destroyed?

18 Behold, if ye had not done this, ye would not have fallen. But behold, ye are fallen, and I mourn your loss.

19 O ye fair sons and daughters, ye fathers and mothers, ye husbands and wives, ye fair ones, how is it that ye could have fallen!

20 But behold, ye are gone, and my sorrows cannot bring your return.
20
21 And the day soon cometh that your mortal must put on immortality, and these bodies which are now moldering in corruption must soon become incorruptible bodies; and then ye must stand before the judgment-seat of Christ, to be judged according to your works; and if it so be that ye are righteous, then are ye blessed with your fathers who have gone before you.
21
22 O that ye had repented before this great destruction had come upon you. But behold, ye are gone, and the Father, yea, the Eternal Father of heaven, knoweth your state; and he doeth with you according to his justice and mercy.
