Geography: The new city of Moroni had been designed as part of the defensive system, guarding the east seaward entrance into Nephite lands. In Sorenson’s correlation to the topography of the Tehuantepec area, Moroni would be located on the northeast of the Nephite territory. The Lamanites would have thus taken a long march around the Nephite lands through the eastern wilderness before emerging onto the lowlands in the gulf. They have not, apparently, used this precise approach before, and it required them to travel farther east than when they attacked Jershon through Antionum. The reason for attacking this particular location was that the Sidon emptied into this gulf. Access to the lower Sidon meant access to the Sidon River Valley, the heartland of the Nephite holdings.
