(We shall see in a later chapter that the shortest distance for them to traverse was along the east sea.) What is said about the military action in that sector contributes to our knowledge of the topography. Not long after Moroni1 became the Nephites’ military commander (see Alma 43:16–17), he was so concerned about the vulnerability of this area that he “caused that his armies should go forth into the east wilderness . . . and [they] drove all the Lamanites who were in the east wilderness into their own lands, which were south of the land of Zarahemla” (Alma 50:7).
