Yuma Army Air Field, located near Yuma, Arizona, played a significant role during World War II as a key training base for military aviators. Established in 1942, the airfield was part of the United States Army Air Forces’ rapid expansion to meet wartime demands for skilled pilots and aircrew.
Throughout the war, Yuma Army Air Field hosted advanced flight training for thousands of cadets, specializing in single-engine aircraft. Its vast desert terrain provided ideal conditions for year-round flying and rigorous training exercises. The base operated various aircraft types, including the AT-6 Texan and P-40 Warhawk, and contributed to the preparation of pilots for combat missions across multiple theaters.
In addition to flight training, the airfield supported gunnery and bombing practice, further enhancing the capabilities of U.S. air forces. After the war ended in 1945, the base was deactivated but later reopened and evolved into today’s Marine Corps Air Station Yuma, continuing its legacy as a vital military aviation facility.
Private C.W. Hilleboe was assigned to the Yuma airfield at the start of WWII. I know this much because I have a picture postcard the private sent Miss Ruby Ellens in Sioux Falls, North Dakota, from Yuma, 71 years ago, on October 1, 1944. The card has a color shot of Yuma’s Main Street on the front, also showing older automobiles of the period.
Before I go any further, let me say that I’ve come across numerous vintage newspaper articles along with postcards having racist undertones. For the most part, I don’t include them in my stories, but in this case, the message that Pvt. Charles William “Bill” Hilleboe sent Ruby Ellens may have been the very reason this couple didn’t stay together.
I decided to print his short note, as written, to prove my point. Imagine that you are Miss Ruby Ellens, having just received this card, or better yet, Ruby’s father. Perhaps Bill didn’t mean what he said, but unfortunately, things came out wrong, especially where drinking alcohol is concerned.
“10-1-44
It isn’t that clean, believe me.
Here’s the card I promised to send you. I would have sent it sooner but last night was my first night in town, also my last. The town is no good. All you see are Mexicans and halfbreeds. One thing though they have plenty of liquor. Believe it or not, I didn’t touch it last night. I am waiting until I get home. Will write you a letter soon. Love, Bill.”
Ruby Jean Ellens was born on February 16. 1922, in Minnehaha, South Dakota. She came from a very religious family, and she was highly active in church as a young person.
Charles William “Bill” Hilleboe was born on March 5, 1924, in Minneapolis, Minnesota. Enlisting in the US Army on June 27, 1942, at the age of 18, he was only 20 when he wrote Ruby Ellens.
Pvt. Hilleboe served as a radio operator on B-17 and B-24 bombers during WWII. He married Barbara Ellen Doherty on June 29, 1946, but that marriage didn’t last. They divorced on May 19, 1950.
Bill then wed Iva Maurine McKinney on October 9, 1950. After leaving the service, he worked as a depot agent for Union Pacific Railroad for 37 years before retiring. Mr. Hilleboe was also mayor and city councilman of his hometown in Idaho, and an active Lions Club officer and participant. The couple had three children.
Bill and Maurine stayed together for 53 years before she died in 2004. Bill died one year later, on May 10, 2005, at the age of 81.
