     17 And it came to pass that Teancum made preparations to make an attack upon the city of Mulek, and march forth with his army against the Lamanites; but he saw that it was impossible that he could overpower them while they were in their fortifications; therefore he abandoned his designs and returned again to the city Bountiful, to wait for the coming of Moroni, that he might receive strength to his army.

     23 For we knew in those cities they were not sufficiently strong to meet them; therefore we were desirous, if they should pass by us, to fall upon them in their rear, and thus bring them up in the rear at the same time they were met in the front. We supposed that we could overpower them; but behold, we were disappointed in this our desire.
