There is no indication that Limhi (or Mormon) knew this information. Perhaps some scouts brought up the rear of the Limhite retreat and observed both the pursuit and when it ended. Why did the tracks of so large a people become untraceable after two days? They passed through a mountainous forest, and the broken vegetation, animal dung, and footprints of so many people would have surely left their mark. It would seem nearly impossible for a following army to “lose” the trail. However, this is a record that is recorded by Limhi. He and his people did not know why they were no longer followed. They knew only that they were not. Whether the speculation on how the army failed to follow them was Limhi’s speculation or a later insertion by Mormon cannot be known.
