Sam didn't attack further, he just let them in. He has to occupy the town to win or he has to kill the peacock. But if he really did kill him from the long shot, how can he achieve his remaining goals. A lot of things are at stake with this war and he has to make it play according to his wishes.
And letting them to go into the town is one of his wishes. This was he can showcase his newly made product and he can earn the big bucks from the southern star Dukedom. So, he is peaceful.
But his counter part the peacock is anything but peaceful.
He is beyond angry. He looked at the Deputy along with thirty others being sent to a temporary tent for them to heal.
It would take some time, Sam isn't any rush to attack, he just hovered with his arms crossed and his soldiers are also recuperating.
The situation would have been ideal and most beneficial for the Peacock's side, but peacock just has to spoil it.
