The waiting game was turning to the disadvantage of the Lamanites. They send out sorties intended to disrupt the supply lines. If they are to successfully siege the city of Judea, they will need to cut off access, and clearly they had not done that. The text does not indicate a full scale attack here, but rather that they began to “sally forth.” The objective is stated as the disruption of provisions rather than the city itself. The very idea that the Lamanites were now willing to leave their strongholds gives Antipus the opening he had been waiting for.
