Looking for Company F 9th Infantry during WW1.

My great uncle was killed on October 3, 1918 in Argonne, France while fighting in WW1. His unit is listed as Company F 9th Infantry. I am trying to find information on that unit, but have been unsuccessful so far. Can someone please help me find the unit he served with?

    Thank you for posting your question to History Hub!

    It seems our community has provided good resources for you to consider. In addition to those suggestions, you might want to consider the information below.
    The Textual Reference Archives II Branch (RR2RR) has custody of the Records of the American Expeditionary Forces (World War I) (Record Group 120).  Military unit files among these records consist mostly of historical reports, operation reports, and unit journals.  While these records focus more on the unit rather than the individual soldier, it is possible that further extended searching by you or your representative would eventually yield some pertinent documents.  The series Records of Divisions, ca. 1918–1942: Records of the 2nd Division (entry P 1241-2) consists of records relating to the 9th Infantry within boxes 36-40.
    In addition, the series Records of the 1st Through 338th and the 559th Infantry Regiment, January 1, 1916–December 31, 1921 (entry NM-93 2133) within the Records of U.S. Regular Army Mobile Units (Record Group 391) consists of records relating specifically to Company F under the 9th Infantry (box 17).  These records consist primarily of company level correspondence during World War I.  
    We will be happy to make the records and their finding aids available to you or your representative in the Textual Research Room (Room 2000) here at the National Archives at College Park, Maryland. Please visit our website for information about visiting the National Archives in College Park, MD, including how to schedule a research visit.
    You may also want to consider requesting rosters and morning reports from our St. Louis location, especially around the time period of your great uncle's death. Morning reports for Army units (from November 1, 1912 to 1959) and copies of most of the monthly rosters from 1912-43 and 1947-59 for Army units (including Army Air Corps) are in the custody of the National Archives in St. Louis, MO. Please contact them for access to these records. The address is the National Archives in St. Louis, 1 Archives Drive, St. Louis, MO  63138-1002 and the email address is stl.archives@nara.gov.    
    We invite you to continue the conversation with community members on History Hub, but should you have follow up questions for the staff at Archives II, please email us at archives2reference@nara.gov so that we can assist you further.

    We hope this assists you with your research!
