You explain that survivors of this Wildling attack will be put to field as beasts of burden, working for betterment of your subjects till they drop dead!
Although few are skeptical, the other agree that this is a good way to punish Wildling children.
505 AD, A Week Later
Over span of seven days your scouts come and go, but there's no sign or sight of any other Wildling groups or encampments, only very old firepits long cold and unused.
You announce the end of the campaign to the joy of your soldiers and officers alike.
Congratulations! Cyrus has completed a military campaign!

506 AD, Midsummer
You meet with a delegation of Druids and beast-tamers in your audience hall.
"My liege, we wish to report that breeding of Mammos is continuing at a steady pace. Few eldest have perished, the mature and young ones were trained, and there have been two dozen calfs already born since the herd was brought into captivity." Says the leader of beast-tamers.
"However, Mammos are fierce, slow to learn and yet are known to hold grudges for long. My companion here--" The beast-tamer turns to the Druid in charge, who bows. "--believes that we need five more years at the least to consider the herd truly tamed and big enough to be of good use."
"And what is your assessment?" You ask the beast-tamer, who smiles proudly.
"We've spent five years raising and training and taming them. I believe they are ready to be put into harnesses and attached to plows. Or we can begin to mount archers and riders on their tall backs for the use of your army!"
A) "Put them to work, our people and land need such great beasts of burden!"
B) "Hm, we've waited five years, we can five years more, just to be on the safe side."
C) "Give them to the army, we shall have those mighty beasts trample our enemies!"
