From my history of my Dad's life:
"World War II was on its way, and West Virginia sent its share of young men to Europe to fight against Hitler. Hibbert, Herbert, and Herman became eligible for the draft. When they drew their numbers, Herbert's was #32 and Hibbert's was over #800. Neither one of the twins wanted to be separated from the other, so they volunteered rather than have Herbert go in alone. They were inducted on May 10, 1941.
