28-year-old Joe DiMaggio was enlisted in the Army on 17 February 1943.
DiMaggio had considered joining earlier, but stayed playing baseball after President Roosevelt urged the Major Leagues to continue during wartime. “I honestly feel that it would be best for the country to keep baseball going,” the President stated. “Everybody will work longer hours and harder than ever before. And that means they ought to have a chance for recreation and for taking their minds off their work even more than before.”
DiMaggio made his decision to join without consulting the New York Yankees. He was denied combat duty, and was instead assigned to “Special Services,” where he mostly played baseball with other soldiers on bases in California, Hawaii, and New Jersey in order to improve morale.
DiMaggio was discharged from the Army on 14 Sept. 1945.
According to one biography of DiMaggio, “he went into the Army, a 28-year-old superstar, still at the height of his athletic powers. By the time he was discharged from the service, he was nearly 31, divorced, underweight, malnourished and bitter. Those three years, 1943-1945, would carve a gaping hole in DiMaggio’s career totals, creating an absence that would be felt like a missing limb.”
While Joe DiMaggio served in the military his parents, Giuseppe and Rosalia, were classified as “enemy aliens” by the US Government since they had been born in Italy. They had to carry ID with them at all times and could not leave a 5 mile radius of their San Francisco home without written permission. Giuseppe, who earned his living as a fisherman, could not enter San Francisco Bay, and his fishing boat was confiscated by the government.
