Geographic: The line of march moves the Nephites towards the North on the west side of their land holdings. To be along the shore they had to have crossed through the mountain range separating the Sidon river valley from the coastal regions. This might be a land renamed after the destruction of Ammonihah, and would consist of that particular territory along the coastal lines. It is certainly to the west of Zarahemla (John L. Sorenson, The Geography of the Book of Mormon. FARMS, 1990, p. 313). Assuming this line of march, Mormon would be leading the pursuing army away from the more central valleys where the greater population lay.
