One who has been captured while fighting under the banner of some state. He is a prisoner, although never confined in a prison. 2. In modern times, prisoners are treated with more humanity than formerly; the individual captor has now no personal right to his prisoner. Prisoners are under the superintendence of the government, and they are now frequently exchanged. 3. It is a general rule, that a prisoner is out of the protection of the laws of the state, so for, that he can have no civil remedy under them, and he can, therefore, maintain no action. But his person is protected against all unlawful acts.
