Moronihah’s advantage continued to be that he had armies distributed along the borders. This allowed him not only to send reinforcements to Bountiful, but to still have armies available to cut off the Lamanite retreat. Coriantumr’s situation was hopeless, and Zarahemla was recaptured.
Perhaps because of lessons he learned from his father, Moronihah allows the prisoners to depart. There is no mention of a covenant, but it would be a reasonable assumption that a covenant existed, even though Mormon isn’t interested enough in this war to give the details of it.
There is no chapter break at this point in the 1830 edition.
