Hi,
Thanks for the reply, the info came from this site

Other information that I have about Edgar Daniel Boone's service record came from NARA.
If I have assumed the POW release wrongly it's the because the description of him is so uncannily correct. In his later life his fair hair, blue eyes and height were always described in many press reports about him.
