It’s also worth noting the term is “capture”. And outside of rare instance - you didn’t really want to kill knights and the like: You captured them, and ransomed them back to their family/liege lord etc.
And there is a reason the term “Kings Ransom” exists. John the II of France for instance was captured, and Ransomed for something like 300000 gold coins of the day - something like 300 million or up to about 3 billion in today’s dollars (conversion is a little fuzzy but to put it simply: A BLOODY TONNE OF MONEY).
I swear, marriage would be easier dealt with if both parties opted to incorporate a business, and put their relevant assets in the name of the corporation. Then at least separation would be pretty clean cut and dry. The Irony is - this is basically what marriage is.
