Alma 53:6–7

And it came to pass that Moroni had thus gained a victory over one of the greatest of the armies of the Lamanites, and had obtained possession of the city of Mulek, which was one of the strongest holds of the Lamanites in the land of Nephi; and thus he had also built a stronghold to retain his prisoners.

And it came to pass that he did no more attempt a battle with the Lamanites in that year, but he did employ his men in preparing for war, yea, and in making fortifications to guard against the Lamanites, yea, and also delivering their women and their children from famine and affliction, and providing food for their armies.
