Mormon 4:15

And it came to pass that in the three hundred and sixty and seventh year, the Nephites being angry because the Lamanites had sacrificed their women and their children, that they did go against the Lamanites with exceeding great anger, insomuch that they did beat again the Lamanites, and drive them out of their lands;

In the year 367, the Nephites were angry because the Lamanites had killed their women and children. They went against the Lamanites with great anger. They beat the Lamanites again and drove them out of their lands.

In year 367, when the Nephites heard that the Lamanites had sacrificed their women and children, they were filled with rage. They attacked with such fury that they beat the Lamanites back and drove them from their lands.
