Se assumirmos que Samwell está abandonando seu posto, então há apenas uma punição ...
Morte!
Desertion is a serious crime in the Seven Kingdoms. It takes place when a man abandons his post, particularly in times of war. Deserters are considered outlaws and thus are marked for death.
Within the ranks of the Night's Watch, desertion is considered a form of oathbreaking. Deserters are not only hunted down by sworn brothers of the Watch but also by lords should a deserter enter his lands.
No entanto, isso não significa que a punição tenha para ser imposta.
Jon Snow briefly deserts the Night's Watch upon learning of his father's execution, intending to join his brother Robb Stark's army. He is convinced to turn back by Samwell Tarly. Jeor Mormont pardons the indiscretion, remarking that if he executed every man who contemplated deserting, they would have no men left.
