This would make for a good movie:
The Boy Who Became a World War II Veteran at 13 Years Old
Graham was just 11 and in the sixth grade in Crockett, Texas, when he hatched his plan to lie about his age and join the Navy. One of seven children living at home with an abusive stepfather, he and an older brother moved into a cheap rooming house, and Calvin supported himself by selling newspapers and delivering telegrams on weekends and after school. Even though he moved out, his mother would occasionally visit—sometimes to simply sign his report cards at the end of a semester. The country was at war, however, and being around newspapers afforded the boy the opportunity to keep up on events overseas.
“I didn’t like Hitler to start with,” Graham later told a reporter. When he learned that some of his cousins had died in battles, he knew what he wanted to do with his life. He wanted to fight. “In those days, you could join up at 16 with your parents’ consent, but they preferred 17,” Graham later said. But he had no intention of waiting five more years. He began to shave at age 11, hoping it would somehow make him look older when he met with military recruiters. Then he lined up with some buddies (who forged his mother’s signature and stole a notary stamp from a local hotel) and waited to enlist.
At 5-foot-2 and just 125 pounds, Graham dressed in an older brother’s clothes and fedora and practiced “talking deep.” What worried him most was not that an enlistment officer would spot the forged signature. It was the dentist who would peer into the mouths of potential recruits. “I knew he’d know how young I was by my teeth,” Graham recalled. He lined up behind a couple of guys he knew who were already 14 or 15, and “when the dentist kept saying I was 12, I said I was 17.” At last, Graham played his ace, telling the dentist that he knew for a fact that the boys in front of him weren’t 17 yet, and the dentist had let them through. “Finally,” Graham recalled, “he said he didn’t have time to mess with me and he let me go.” Graham maintained that the Navy knew he and the others on line that day were underage, “but we were losing the war then, so they took six of us.”
