John Sorenson notes an incident that took place on Moroni's return after helping Pahoran and which sheds more light on routes of march between the land of Gideon and the land of Nephihah. According to Alma 62:14-15:
And it came to pass that Moroni and Pahoran, leaving a large body of men in the land of Zarahemla, took their march with a large body of men towards the land of Nephihah, being determined to overthrow the Lamanites in that city.
And it came to pass that as they were marching towards the land, they took a large body of men of the Lamanites, and slew many of them, and took their provisions and their weapons of war.
According to Sorenson, clearly the particular route described in these verses was not controlled by either side. . . . The story does not tell us enough that we can establish where the encounter took place, but for both to use the upper Teapa River Valley above Pichuacalco would make sense, or it could have been nearer to the Sidon, close to modern Huimanguillo.
