I understand there were rules of combat even way back then, and chivalrous codes and rules for taking prisoners and ransoms etc. Did they actually have courts and punishments metered out for breaking the rules? Mea Culpa if so, but one hardly looks at the middle ages, filled with horrible torture and complete disregard for human life, when one thinks of restricting war crimes.
“Whoa, whoa, whoa, Sir Thomas. Look we just sacked and raped this castle, and we were going to take this guy out and shove a hot poker up his ass while making him eat his own tongue tomorrow! You can’t just cut off his head with his hands bound! We have rules! We aren’t mindless savages!”
