Ether 14:31

Now the loss of men, women and children, on both sides, were so great that Shiz commanded his people that they should not pursue the armies of Coriantumr; wherefore they returned to their camp.

So many men, women, and children on both sides had died. So Shiz told his people not to chase Coriantumr’s armies. They went back to their camp.

The casualties on both sides—men, women, and children—were so staggering that Shiz ordered his people to stop pursuing Coriantumr’s army. So they returned to their camp.
