Little Goat Mountain Father says

he was enthralled by the hunt, and eivor fell back somewhat, allowing the boy to swing his body more easily.

the creature bleated pitifully as she grabbed for one leg, slamming its hip into the stone.

an off-balanced moment took place; it stumbled there upon the ledge and she grunted sharply for the boy to overpower it with another blow. if their aim was true, into open space the animal would fall. they needed only then to collect themselves below.
