Lewis's remarkable military career spanned two significant conflicts, with his first stint serving with the Marines during World War II. Following the war, he transitioned to a civilian role, joining the editorial staff of the Santa Ana Register in California, while also pursuing a career in screenwriting, penning scripts for notable actors such as Johnny Mack Brown and Lash LaRue.
However, in 1950, Lewis was called back to active duty with the Marines, this time serving in Korea. As one of the initial American forces to set foot in Wonsan, North Korea, he played a pivotal role in the city's liberation from communist control. After completing his first tour of duty, Lewis returned to the United States, only to volunteer for a second tour in Korea, where he spent an impressive 14 months.
By the time Lewis finished his second tour in 1953, he had achieved significant career milestones, being promoted to the rank of captain and being awarded the prestigious Bronze Star, the Air Medal, and the Commendation Medal, a testament to his bravery, dedication, and selfless service.
