Enos Slaughter made his big league debut in 1938 and was an All Star by 1941. The following season he was again an All Star, leading the National League in hits, triples, and total bases while finishing second in MVP balloting. His Cardinals beat the Yankees in the World Series to give Slaughter the first of his four rings.
After the Series ended, Slaughter joined the war effort, enlisting into the United States Air Force. Denied being a pilot because he was colorblind, Slaughter became a physical education instructor and eventually gained the rank of sergeant. In 1945, he toured the South Pacific with other big leaguers playing exhibition games in Tinian, Saipan, Guam, and Iwo Jima. He was discharged early the next year before the start of the 1946 baseball season.
Slaughter returned to the game in All Star form, leading the NL in runs batted and finishing third in MVP balloting. The Cardinals reached the World Series where they earned another ring for Slaughter.
