A year or so back a soldier from WWII was returned to my hometown.
He died of disease in a German POW camp and the Germans held a funeral for him including a headstone. For some reason his family just assumed it was propaganda and that he was in a mass grave.
It turned out that he really was buried where the Germans said.
