(3rd PoV)
The commander was able to instil fear and morale in the troops that were on the wall.
Many were considering to desert but they knew that if they did so now, they would be branded as deserters and no one would hire them in the future. Even if they did, that would be for a dirt cheap price.
Once they were branded as deserters, no guilds would be interested in buying their hunt either. So they have to sell that for cheap too.
There is another choice for them though. In fact, there are many choices.
They can sell in the black market, which was not regulated by the kingdom or any guild that operates in the open. Though it is illegal, many turn a blind eye to the operations. It was said that the black market was run by some powerful nobles, which is why it has survived to this day.
