As the Lamanites marched against the Nephites they took Nephite women and children as prisoners, and these they sacrificed to their pagan gods. This so angered the Nephites that they attacked the Lamanites ferociously and were able to drive the enemy out of their lands. This was their last victory. They would never again have power to defeat the Lamanites. It seems probable that Mormon’s people, who themselves delighted in bloodshed, whose wickedness could not be described, were angry that Nephite bodies were being sacrificed rather than being repulsed by Lamanite human sacrifice. It is also a sad commentary that even given the abominable Lamanite practice of human sacrifice to pagan gods and other atrocities, Mormon admits that the Lamanites were still no more wicked than some of his people (see Moroni 9:7-10).
