Alma 56:29

And the Lamanites, thus seeing our forces increase daily, and provisions arrive for our support, they began to be fearful, and began to sally forth, if it were possible, to put an end to our receiving provisions and strength.

The Lamanites saw our army getting bigger every day. They saw supplies coming to help us. They got scared. They tried to stop us from getting more supplies and help.

“When the Lamanites saw our forces growing daily and supplies continuing to arrive, they got nervous. They started making raids, trying to cut off our supply lines and reinforcements.”
