Alma 62:21

And it came to pass that they were on the east, by the entrance; and they were all asleep. And now Moroni returned to his army, and caused that they should prepare in haste strong cords and ladders, to be let down from the top of the wall into the inner part of the wall.

They were on the east side by the entrance. They were all asleep. Moroni went back to his army. He told them to quickly prepare strong ropes and ladders. These would be let down from the top of the wall into the inner part of the wall.

He saw that they were camped on the east side, near the entrance, and they were all asleep. Moroni returned to his army and ordered them to quickly prepare strong ropes and ladders to lower themselves from the wall into the city.
