I did find in my dad's old papers where-- when he returned to the states he had to file his army discharge papers at the county clerks office in the county that he lived in at the time of discharge. If you know where he lived during that time check with the county clerks office and hopefully you can get a copy of his army discharge papers. On the paperwork it gives a lot of information. It also tells if they received any medals etc.
My dad never mentioned the service. It changed him being in the military. Maybe something happened that he did not want to remember. I guess I will never know.
Keep in touch maybe we will find out something one of these days.
