Early Life

James Calven Thomas was born on October 27, 1947, to Jim and Govie Fortman Thomas in Marshall, Texas. Thomas grew up in a household with seven other children. 

The 1940 census shows his mother, Govie, widowed with three daughters (Luella and Ludella, who were twins, and their younger sister Willie). In 1946, she married Jim Thomas, James’s father. 

In 1950, Govie was the head of the household with seven children ranging in age from 14 to an infant. She supported her children working as a dishwasher in a cafe. 
The Thomas family eventually made their way to Safford, Arizona.

Homefront

The Thomas family moved to Safford, Arizona, a small, rural area known for farms and cattle ranches. Agriculture was the leading economic activity with cotton being the main commodity. In the 1950s and 1960s, Safford saw a significant population increase and continued to remain an agricultural hub.

During the Cold War era, Arizona established various manufacturing and production facilities to support the Department of Defense. This included the emergence of military installations, industrial testing facilities, and airframe and missile production facilities. Small towns, like Safford, were especially vital, where mines produced significant amounts of uranium ore and other minerals to build America’s nuclear weapons arsenal.

Military Experience

While residing in Safford, Arizona, James Thomas enlisted in the U.S. Marine Corps in 1967. He attended boot camp in San Diego, California. After completing bootcamp, he became a rifleman with the 1st Marines, 7th Marine Regiment, 3rd Battalion, Company I and shipped out for South Vietnam. 

While in Vietnam, Thomas and his fellow Marines had numerous tasks to complete. Covering an area of over 10,00 square miles, the Marines defended critical bases and airfields, destroyed Communist combat forces, eliminated Communist infrastructure and conducted civic action to support the government of South Vietnam. Thomas was responsible to ensure that he was always ready to fight and all of his weapons were maintained in any terrain or weather.

Commemoration

On April 3, 1968, Thomas’s company participated in a routine combat patrol sweeping the area near An Hoa in Quang Nam Province, South Vietnam. The group stopped for a rest break and noticed a few Vietnamese boys along the side of the road begging for handouts. Thomas walked to a nearby stream outside of the security position. No one noticed that he was missing until the next rest break. The entire area was searched and his helmet, pack, and canteen were the only items retrieved. Thomas, and his weapon, were never found. 

After his disappearance, Thomas was promoted to staff sergeant and was awarded the Purple Heart and the Prisoner of War Medal. 

Thomas was not among the returned Prisoners of War of the Vietnam War, and his remains were not recovered or returned to American custody since the end of the Vietnam War. He was declared dead on August 12, 1975. 

He is memorialized on the Honolulu Memorial at the National Memorial of the Pacific in Honolulu, Hawaiʻi, and Panel 47e, Line 57 with his fallen comrades on the Vietnam Veterans Memorial Wall in Washington, D.C. His family placed a memorial marker for Thomas at Fort Rosecrans National Cemetery in San Diego, California.
