How were men treated in the jail that is in opposition to what the District Commissioner tells the guard to do?

The Commissioner told the men:

"We shall not do you any harm," said the District Commissioner to them later, "if only you agree to cooperate with us. We have brought a peaceful administration to you and your people so that you may be happy. If any man ill-treats you we shall come to your rescue. But we will not allow you to ill-treat others. We have a court of law where we judge cases and administer justice just as it is done in my own country under a great queen. I have brought you here because you joined together to molest others, to burn people's houses and their place of worship. That must not happen in the dominion of our queen, the most powerful ruler in the world. I have decided that you will pay a fine of two hundred bags of cowries. You will be released as soon as you agree to this and undertake to collect that fine from your people. What do you say to that?"

The guards:

"As soon as the District Commissioner left, the head messenger, who was also the prisoners' barber, took down his razor and shaved off all the hair on the men's heads."

"The six men ate nothing throughout that day and the next. They were not even given any water to drink, and they could not go out to urinate or go into the bush when they were pressed. At night the messengers came in to taunt them and to knock their shaven heads together."
