They begged the Americans not to turn them over to their countrymen, because they knew what would happen if repatriated.
I worked for a civil engineering firm in Boston for 4 years during the late sixties and early seventies. It was a summer and college vacation job. Anyway, the two owners were a couple of Germans named Fritz Gruber and Fritz Peterson. They had been captured during the war and sent to POW camp in Massachusetts. During their time in the US, they were given the opportunity to earn engineering degrees from Boston University. They stayed on in the US after the war and became citizens. After getting additional education and experience, they started up their own company, Boston Survey Consultants. Not a bad outcome for Fritz and Fritz. They were actually nice guys and made good citizens. Not to mention that my job with their company put me through college.
