Ernest Wrentmore of Ohio served the United States in three wars. His service included fighting with considerable distinction with the AEF's 5th Division in the Argonne Forest. There is one detail, however, that sets Wrentmore apart from all the other troops who served with the AEF.
The photo shown was taken after the Armistice when Wrentmore was all of 14 years old—he actually had enlisted when he was still 12 years old! Later, he served in the Army Air Force and U.S. Air Force, attaining the rank of full colonel as an intelligence officer. After his death in 1983, a bill was introduced in Congress to award Wrentmore the Medal of Honor, but it was not passed.
