After describing Ammon's joy and rejoicing, Mormon returns to the narrative history. He picks up where he left off in Alma 25:13, where he said, And it came to pass that when the Lamanites saw that they could not overpower the Nephites they returned again to their own land. This Lamanite army was a diverse group of Lamanites, Amalekites, and Amulonites. By way of review, the Amulonites, or descendants of the wicked priests of Noah, were scattered, driven and executed according to the words of Abinadi (Alma 25:8-9). Some of the Lamanites were converted and joined the people of Anti-Nephi-Lehi (Alma 25:14). The third group, the Amalekites, never tired of making life miserable for the righteous. Angry that they couldn't kill more Nephites, they stirred up the Lamanites against the people of Anti-Nephi-Lehi. We are approaching the section of the Book of Mormon which deals primarily with warfare. The Amalekites continue to be one of the main forces for destruction among the Lamanites, Zerahemnah appointed chief captains over the Lamanites, and they were all Amalekites and Zoramites. Now this he did that he might preserve their hatred towards the Nephites, that he might bring them into subjection to the accomplishment of his designs. For behold, his designs were to stir up the Lamanites to anger against the Nephites (Alma 43:6-8).
