I just found out that my grandfather served in WWII and was involved in the Battle of the Bulge. He was wounded and received the purple heart and was sent back as an interperter because he spoke Low German and High German. I don't know what that really means yet. I always new he was enlisted but did not know he actually fought. How can I find out more information. My family does not seem to know much about it. Thanks for any help or advice.
