Moroni prepares the Nephites and their cities, to focus on God and their freedoms. He built ditches, walls of dirt, walls of stones, towers to have look outs, armies to stand guard. Amalikiah and the Lamanites were shocked the Nephite preperation. The Lamanites armies did not dare attack. The Nephites had all power over their enemies. Moroni and the Nephites did never stop fortifying!
