Although Auron's side had fewer number, however they managed to push the enemies front line back. But, they didn't go to far from the village.
After pushing, the enemies attack back for 1 kilometers from the village, they didn't chase the enemies, instead they maintain their position and took care of the injured. This was what Fourth Prince had ordered.
They feared the sudden ambushed if they had went to far. Since they didn't know the situation out there, they didn't want to play at the palm of their enemies hand. That was why the Fourth Prince only ordered them to push as far as 1 kilometers from the village.
Seeing Auron's side didn't chase them out of 1 kilometer, the enemies felt confused as well as relieved. Moreover, the enemies upper high didn't gave any command, so they didn't dare to backed out and attacked once more.
