The 320th Machine Gun Battalion (MG Bn) was assigned to the 163rd Infantry Brigade of the 82nd Division. In the early stages of the Meuse-Argonne Offensive, the 163rd was held in Corps Reserve. The Brigade was released from reserve on the night of October 8/9 and relieved troops of the 28th Division from two kms. west of Hill 223 through Drachen to a point 2 1/4 kms. west of le Menil Fme. Again, refer to the Order of Battle of United States Land Forces in the World War and American Armies and Battlefields in Europe, both of which are available on a CD from the US Government Printing Office or in bound form from your local library on inter-library loan. The Armies and Battlefields work has maps. The best recent history of the 82nd Division is The All-Americans at War: the 82nd Division in the Great War, James J. Cooke, Greenwood, 1998, ISBN 0 27595 740 3. There is also an 82nd Division website. Seek more information on the 82nd via Google or another search engine. Some, or perhaps many, but by no means all WWI personnel records were destroyed by fire. NARA is attempting to reconstruct these records. If you have your subject's service number from the NY State Archives, you should initiate a search with the Personnel Records Officer of NARA outside St. Louis. For guidance on records research, consult the Doughboy Center website (_www.worldwar1.com/dbc_ (http://www.worldwar1.com/dbc) ) looking under Second Army. More sources of information on the AEF is to be found on the Western Front Association website at _www.wfa-usa.org_ (http://www.wfa-usa.org) looking under Resources. Good luck! LGS
