“I noticed that article particularly because there were so few escapes or attempts (as a percentage) from POW camps in the U.S.”
Escape to where? The USA is a big country with two big ponds intbetween. No going North as they were with us.
I have read most were happy to get out of the action and the Wiki page on US POW camps notes they were not bad place to hangout for a year or so.
Exactly. If you're in Oklahoma and escape from the camp, where are you going to go?
