O'Dowd was the only world's champion to fight at the front during World War I (1918, while serving in the U.S. Army).
"Mike O'Dowd, fighting Irishman of St. Paul, who formerly held the world's middleweight title, will be out of ring competition for a period of at least two months. The former champion was operated on for a hernia, yesterday at St. John's Hospital, Long Island." New York Times, March 24, 1921. (The hernia happened during the Johnny Wilson fight on 1921-03-17.)
The linked record shows O'Dowd's verified fights. He is also supposed to have fought seven times in 1913, as follows:
Mike Brown (in Superior WI), W ko 1; Al Johnson, W ko 1; Harry Olson, W ko 1; Harry Gardner, W ko 4; Al Johnson (in St. Paul MN), W Points 6; Jack Pleunbush, W ko 2; Charley Fuhrman, W ko 2.
