Helaman, being alert to the importance of provisions, surrounded the city of Cumeni “a little before the Lamanites there were to receive a supply of provisions” (v. 8). Helaman’s band picked off the Lamanite supply trains going into the city, and took them and their prisoners of war far away to Judea. Cumeni was retaken after the Lamanites lost all hope of receiving supplies and left without conflict.
