German and US POW aviators defect/escape together?

[Brian Bines]

My German is not too hot but if I read the article in RolandF's post correctly it says the four Germans were sent to a Yugoslav labour camp . The 2nd pilot Christian ? and the fourth unnamed man were shot escaping from the Labour camp, Fredl the pilot was injured at the camp sent home but his neighbours ignored him as a traitor, while Bernhard Kersting ( son of a prominent industrialist) was released after 5 years at the camp.
Any confirmation/ corrections appreciated
