“Francs-tireurs (a term originating in the Franco-Prussian War) are enemy civilians or militia who continue to fight in territory occupied by a warring party and do not wear military uniforms, and may otherwise be known as guerrillas, partisans, insurgents, etc. Though they could be legally jailed or executed by most armies a century ago, the experience of World War II influenced nations occupied by foreign forces to change the law to protect this group.”
Sorry I hadn't read the whole thread: I agree the "false colors" sense of perfidy generally is granted due process. I was thinking of the "feigning surrender" sense of perfidy, which is pretty much universally met with summary execution.
This is my fault; I hadn't read the whole thread. There's two acts that constitute perfidy: one is wearing false uniforms or displaying false colors; I agree that isn't usually met with summary execution. The other one is taking back up arms after signalling a surrender. That is absolutely met with summary execution.
