Enemy combatants captured in wartime are both a potential resource for their captors and a logistical and security nightmare. This has long been reflected in their treatment. Over the centuries, captured enemy combatants have been sold as slaves (or simply used as slave labour), forced to switch sides, ransomed for money, swapped for other prisoners, physically maimed to ensure they could no longer fight, starved to death, imprisoned under abysmal conditions, or outright massacred. And yet, surprisingly, at other times (including in the period covered by this book), most prisoners of war – though not, as Morieux shows, all – have not only had a protected status but, especially in the case of officers, been allowed a degree of freedom of movement that seems extraordinary by modern-day standards.
