A prisoner-of-war camp is a site for the containment of combatants captured by their enemy in time of war, and is similar to an internment camp which is used for civilian populations. A prisoner of war is generally a soldier, sailor, or airman who is imprisoned by an enemy power during or immediately after an armed conflict. Some non-combatant enemy personnel, such as merchant mariners and civil aircrews, were also considered prisoners of war.
