There's two ways to go at this point.Depending on what records St Louis has, they might have the General Order number.
The other way to go is to contact Nat. Archives, Modern Military Records, and request copies of the early 5th Infantry Division General Orders for 1945.My experience has been that if you give them a limited date range (like Jan-Feb 1945)and Fred's name, they'll find the right GO.They won't do time-consuming research projects (like look through every GO for the 5th ID for the entire war). You can request copies on-line at http://www.archives.govhttp://www.archives.gov
Have you requested Fred's Individual Deceased Personnel file? If not, see my message 10907 on this board to find out how.There are documents in this file that will confirm the issuance of the CIB.He was definitely with a front line combat unit, so my educated guess is that he did indeed earn a CIB. The IDPF will not have information on his awards, however.
It's true, you might not find out exactly why he received the BS, even though he is listed in a GO.Typically I see BS GO's that are only a few lines.I have also seen very detailed BS citations.It's definitely worth trying to get.
