World War One was not the first time American soldiers died and were left on foreign soil.  The Great War did leave by far the largest number of dead Americans outside the native country, however.  To establish and maintain cemeteries outside the United States to honor the sacrifices made by so many, the American Battlefield and Monuments Commission was set up in 1923 headed by no other than General John Pershing.  There are 28 cemeteries falling under the guise of the ABMC today.  Here is the ABMC St Mihiel Cemetery filled with soldiers many falling during the first offensive campaign fought by the US Army as a cohesive unit – St Mihiel.
