Ether 13:18–19

Wherefore, it came to pass that in the first year that Ether dwelt in the cavity of a rock, there were many people who were slain by the sword of those secret combinations, fighting against Coriantumr that they might obtain the kingdom. And it came to pass that the sons of Coriantumr fought much and bled much.
