Alma 52:30–32

Now Lehi was not desirous to overtake them till they should meet Moroni and his army. And it came to pass that before the Lamanites had retreated far they were surrounded by the Nephites, by the men of Moroni on one hand, and the men of Lehi on the other, all of whom were fresh and full of strength; but the Lamanites were wearied because of their long march. And Moroni commanded his men that they should fall upon them until they had given up their weapons of war.
