How Could So Many People Have Died at the Battle of Cumorah?

KnoWhy #231 | August 20, 2020

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

Mormon 6:14

The Know

In the final battle at the Hill Cumorah, the Lamanites completely decimated the Nephites. Mormon stated that the Lamanites killed roughly 230,000 of his people.1 Yet this number may, at first, seem impossibly large. One wonders how an army of 230,000 people could exist during a time when the entire population of the world was probably only around 206 million.2 It is impossible to know exactly why these numbers are so high, but there are a few possibilities.

1. Mormon May Have Exaggerated

The first thing to consider is that ancient texts often exaggerate population sizes.3 In the Old Testament for example, 600,000 Israelite males are said to have left Egypt (Exodus 12:37).4 When one considers the women and children that left at the same time, this would mean that 2.5 million Israelites likely left Egypt at the same time. Seeing that the entire population of Egypt at the time was likely only 2.8 million, these numbers seem to be clearly exaggerated.5 It is therefore possible that Mormon, like other ancient historians, simply exaggerated when talking about numbers this large.6

2. A Thousand May Not Actually Mean a Thousand

It is also possible that “ten thousand” represents a military unit and not an exact number of soldiers. In Hebrew, the word eleph can mean the literal number 1,000, but it can also mean a military squad.7 If this is the case, each military commander could simply have been in charge of 10 “squads” of unknown numbers, putting the number of casualties much lower than they might seem at first.8

3. The Army May Actually Have Been Massive

Depiction of the Nephites' Final Battle. Artist Unknown.While it is important to be aware of these different possibilities, some evidence suggests that these figures are accurate. The population of pre-Columbian America was much larger than many people assume. In fact, during many periods, the Americas were more populous than Europe.9 Thus, 230,000 casualties may have been a reasonable figure in Mormon’s day. The Book of Mormon’s own population data is consistent with this figure. As one examines the occasions when population size is mentioned throughout the Book of Mormon, and assumes normal population growth, 230,000 deaths in the final battle at Cumorah would make sense.10

One sees this from the size of actual armies in pre-Columbian America. In Mesoamerica, for example, even after rounding down significantly to account for the above-mentioned tendency of authors to exaggerate, the Aztecs gathered together more than 300,000 people for a war against a neighboring kingdom, and this was not noted as a remarkable event. The Quiche, similarly, were able to put an army of 232,000 men into the field, even though many refused to fight.11 This demonstrates that the casualty figures in Mormon are at least feasible.  

4.  230,000 Could Represent Entire Population

Drawing of the final battle at Cumorah by Terry RutledgeOne disturbing possibility presented by Mormon 6 is that most of the Nephite population, including women and children, fought in this battle and were killed.12

Mormon stated that

[all his] 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 (Mormon 6:7, emphasis added).

Later, Mormon lamented, “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!” (Mormon 6:19, emphasis added). Although it is impossible to say for sure, these verses strongly imply that the entire population fought the Lamanites, and that the 230,000 figure represents that.13

The Why

The Last Battle Between the Nephites and the Lamanites by Minerva Teichert

There are two overarching approaches one can take when reading the Book of Mormon. One is to assume that the book is false, stating that each confusing element in the book proves it to be a fraud. The other is have faith, give the book the benefit of the doubt, look at it through an ancient lens, and realize that ancient texts are rarely as clear cut as modern readers would prefer. This second approach means that readers of the Book of Mormon need to read it in the same way that they might read other ancient sacred texts. They need to be patient with the book, consider it thoughtfully, and not dismiss details that seem strange as a sign that the book is not authentic.14

As one examines the possible answers to the question of such high casualty figures, interesting implications arise:

  1. If the numbers are exaggerated, this is a reminder to the reader that the Book of Mormon was written like many other ancient texts.
  2. If the word “thousand” actually represents military units, this gives the reader a fresh insight into the translation of the Book of Mormon.
  3. If the numbers are accurate, this shows attention to accuracy of details that is exceptional in an ancient text.
  4. If the number actually represents the whole population, this reminds of the reader of the tragic nature of this final battle of the Book of Mormon.

Exploring difficulties and potential solutions available—rather than dismissing them out of hand—creates opportunities to learn, discover, grow, and ultimately increase in faith.15 If something about the Book of Mormon seems confusing, out of place, or unexpected, this is what one would expect. This simply means that the Book of Mormon joins the Bible as a book that needs to be pondered and considered carefully if one is to understand seeming oddities in the text.

Painting by Walter Rane

Regardless of if there were 23,000 killed or 230,000 killed, the destruction was an absolute tragedy, and a horror for Mormon and Moroni to witness. This is the appalling climax of action for the whole Book of Mormon narrative. A people who were blessed and righteous for so long ultimately destroyed themselves in senseless acts of violence and carnage.

In a day when senseless acts of violence frequently trouble modern nations, it is easy to imagine the emotional effect on the Nephites. Similarly, wars raging across the earth today kill millions. If the modern reader feels compassion and heartbreak for the victims and families of wars and shootings that people from the US experience, then how much more should the reader feel compassion and heartbreak for the destruction of the chosen and blessed Nephites. Yet if the reader feels such poignancy for the Nephites, how much more should they now turn with compassion to those suffering the ravages of war and violence today. And if the reader is filled with compassion for those suffering today, consider how much more God weeps and is heartbroken over the destruction of His children (Moses 7:29, 32).

  • 3. “In contrast to the texts of other ancient Near Eastern cultures which typically provide relatively little information about the size of their armies, the Bible includes a great deal of information about the number of Israelite troops. Unfortunately, much of this information is problematic. . .  The numbers appear quite high, especially considering the apparent size of the armies of other, better established contemporary nations. . .  This difficulty has led many to discount the biblical numbers altogether, or consider them to be intentional exaggerations. Clearly, the Bible does include exaggerations. . . Thus, some argue that the biblical numbers often also exaggerate to make certain points, such as glorifying the God of Israel.” Boyd Seevers, Warfare in the Old Testament: The Organization, Weapons, and Tactics of Ancient Near Eastern Armies (Grand Rapids, MI: Kregel Academic, 2013), 53.
