Wyoming and World War II

Wyoming and World War II

One of the first Wyoming men killed during the Second World War was also one of the last to return home.

Navy Machinist’s Mate First Class George Hanson died on Dec. 7, 1941, when the Japanese attacked Pearl Harbor, Hawaii. He was among 429 servicemen killed when torpedo bombers assaulted the battleship USS Oklahoma, capsizing it.

Hanson was not identified until more than 70 years later, thanks to advances in identification technology. In 2019, his remains were buried at Greenhill Cemetery in Laramie, Wyo.

In all, 1,095 Wyoming servicemen died in the fighting or from related injuries. No county in the state was spared.

The Second World War galvanized the nation, forging in fire what some observers have called the “American spirit.”

The war "strengthened us as a country," historian Stephen Ambrose said in a National Geographic interview. "We were much more committed to the idea of country, rather than region. People didn't speak of themselves anymore as being, 'Well, I'm a Rebel, I'm from Mississippi.' 'I'm a Yankee, I'm from Wisconsin.' [It was], 'I'm an American.' That would always spring first to their lips.

“We're all in this together, and we will fight it out together,”  Ambrose said.

War bonds

In Wyoming, patriotic fervor took many forms. War bond drives were conducted throughout the war. In 1942, people were asked to invest 10 percent of their paychecks in war bonds or “to the limit of their ability.” By February 1943, 25,000 workers in 303 businesses were enrolled in the plan.

Communities also were encouraged to buy bonds for particular aircraft; for example, $450,000 invested in bonds would purchase a heavy bomber. Movie stars like Ronald Colman and Ann Sheridan helped sell bonds in several towns; a $1,000 bond entitled the buyer to lunch with stars in Casper and Cheyenne.

Newspaper editorials extolled the virtues of bond buying, while feature articles highlighted exemplary behavior—a sheepherder using his entire paycheck to buy bonds, for example, or the Eastern Shoshone tribe authorizing the Interior Department to purchase bonds with interest from the tribe’s judgment fund.

Scrap metal

Collecting scrap metal was another popular way for folks on the home front to support the troops. In Wyoming, agricultural scrap fetched 40 to 50 cents per 100 pounds from dealers, or it could be donated to the American Legion or Red Cross.

The town of Medicine Bow, Wyo., population 338 in 1940, conducted two scrap metal drives. The first yielded a stack of steel, iron and copper, which was piled next to U.S. Highway 30. Locals wrote messages on the scrap, “Special delivery to Hitler” and “This one is for you, Tojo.”

A crowd turned out when the pile was collected. Speeches, a high school band and dancing to Dixieland jazz capped off the day.

One controversial Cheyenne scrap metal donation left some people scratching their heads. Officials decided to remove captured World War I German artillery pieces from the state house lawn—over objections from the Wyoming Stock Growers Association.

“Why do we sit back and permit things to be destroyed that stand for our traditions?” association secretary Russell Thorp asked. “Why do we have to destroy things that create interest in and respect for the very ideals that we are now fighting to preserve?”

The objection did not persuade state salvage officials, who sent the howitzers to a smelter anyway.

Red Cross and Victory Gardens

Organizations ranging from the Red Cross to Camp Fire Girls aided the war effort.

Red Cross sewing rooms provided garments for soldiers and refugees. A national Red Cross publication reported an interview with a Russian woman in Stalingrad who proudly showed off items marked, “Gift of the Sheridan County Chapter, American Red Cross, Sheridan, Wyoming.”

Young people joined the Victory Book Campaign to provide reading materials for servicemen. In 1943, the national book drive slogan was, “Any book you really want to keep is the one to give.” Recommended donations included recent technical works, current bestsellers, Westerns, detective stories and books of humor.

Residents across the state also planted so-called Victory Gardens. According to one estimate, Wyoming’s production of garden foodstuffs doubled during the war years. The Union Pacific and Burlington Northern railroads even offered the use of their rights-of-way to plant gardens.

Attack on the Cowboy State

Occasional enemy attacks on American soil occurred or were planned during World War II. A Japanese submarine lobbed several rounds on a California oil field in 1942, and the FBI broke up a sabotage scheme by German agents.

The strangest attacks came in the form of Japanese balloon bombs, called Fu-Gos. These were the ultimate dumb bombs. Fu-Gos were high-altitude balloons loaded with incendiary or antipersonnel bombs released in Japan, with hopes that after a flight to the U.S., they would destroy something significant.

The only fatalities occurred in Oregon, where a woman and several children were killed after trying to retrieve a downed balloon. Their deaths are considered the only combat casualties on continental U.S. soil during the war.

In late 1944, witnesses reported Fu-Go sightings around the West. In Wyoming, people at a coal mine near Thermopolis said they had seen “a parachute in the air, with lighted flares and after hearing a whistling noise, heard an explosion and saw smoke in a draw near the mine about 6:15 p.m.,” according to an article in the journal World War II.

In 1945, the Office of Censorship asked newspaper editors and broadcast managers to suppress information about balloon incidents to prevent the Japanese from obtaining useful targeting data.

After Japan’s surrender, the Associated Press commented, “The Japanese listened eagerly to radio reports, hoping to hear of the bombs’ effectiveness. But American editors voluntarily kept the information to themselves and so discouraged the Japanese that they abandoned the project. The Japanese learned of only one bomb landing in the United States. It was one which came down in Wyoming and failed to explode.”

Whether the AP’s Wyoming reference is related to the Thermopolis incident in which a balloon bomb reportedly detonated is unclear.

Oil and coal production

By 1941, many Wyoming towns had oil refineries, but one in Cheyenne played a particularly direct role in the war effort.

The Frontier Refining Company’s 100-octane fuel plant produced high-grade gasoline for airplanes. Defense analysts felt 100-octane plants should be built close to oil fields but far away from the coasts and thus less vulnerable to enemy air or sea attacks. The fuel increased the performance and range of aircraft and had proven its effectiveness during the Battle of Britain in 1940. But opening the Cheyenne plant proved a lengthy process, and it did not go into service until 1944.

Feeding America’s war machine with petroleum products was a national priority. Quotas were established for each state, which put considerable demands on Wyoming producers early in the war that was compounded by price restrictions. Even so, oil production generally increased, from 25.6 million barrels in 1940 to 35.4 million in 1945. Important discoveries occurred in deeper zones of the Elk Basin, Oregon Basin and Little Buffalo Basin fields.

Wyoming coal production increased from 5.8 million tons in 1940 to 9.8 million tons in 1945. Two-thirds of the state total came from Union Pacific Company mines in the Hanna-Rock Springs area. Most of it was used by U.P. steam locomotives as wartime traffic increased. By the summer of 1945, more than a hundred trains a day were passing through Laramie.

Shortly after Pearl Harbor, Gov. Nels H. Smith ordered law enforcement to require Japanese non-citizens in the state to register. Laramie County listed 103 such persons, followed by Sweetwater County with 45, and Carbon County with 33. Japanese working in the Rock Springs-Hanna coal mines were allowed to keep their jobs. But those working for the railroad were fired, according to an article in the Rock Springs Rocket-Miner.

At least some terminated Japanese railroad workers ended up working for the Thomas Boylan family. The Boylans built “the world’s oldest cabin”—constructed of dinosaur bones—along U.S. Highway 30 east of Medicine Bow. To avoid confrontations, the Boylans reportedly told people the workers were Samoan.

The federal government also investigated technology to produce synthetic fuel derived from coal and oil shale, initiated by the Synthetic Liquid Fuels Act of 1944, but little came of it.


Before the war, agricultural producers often were plagued by surpluses and low prices. But with the outbreak of hostilities, shortages replaced surpluses, and the federal government aggressively tried to manage the food supply. Annual production goals became marching orders of a different sort.

The U.S. Army Air Base in Casper opened in 1942 to train bomber crews. Here, a B-24 flies above the control tower. Casper College Western History Center. Wyoming’s efforts to reach its targets were sometimes hampered by labor and machinery shortages. Even so, only sheep and sugar beets failed to maintain pre-war production levels.

The most significant increase came in cattle production, which went from 827,000 head in 1941 to a million head in 1945. Part of the growth came when producers switched from sheep to cattle.

Acute agricultural labor shortages developed after Pearl Harbor, as men enlisted, were drafted or relocated for work in war industries. In 1942, a statement from the Stock Growers convention in Gillette declared that the Selective Service, which drafted men for military duty, was “the biggest single threat to the industry.”

After state livestock and Selective Service officials conferred on the matter, Cow Country published instructions on how key personnel on ranches could seek draft deferments. Not long thereafter, the federal Tydings Amendment allowed deferments for people deemed essential to agriculture until satisfactory replacements could be found.

Military training and refitting

The Casper Army Air Base was constructed to train bomber crews for overseas assignments. About 400 buildings and four runways each a mile long were built in a matter of months; the base was activated on Sept. 1, 1942.

The base’s initial mission to train crews for B-17 bombers soon changed to training B-24 crews. During 30 months in operation, the base prepared an estimated 16,000 men for war. It was officially deactivated on March 7, 1945.

Today, the Wyoming Veterans Memorial Museum occupies what had been the base Servicemen’s Club.

In 1942, United Airlines relocated its pilot training school to Cheyenne. A center was soon added where B-17 and B-24 bombers fresh off the assembly line were modified with new guns and instruments.

At one point, the modification center employed 1,600 people, half of them women. By the war’s end, more than 5,000 bombers had been prepared at the facility.

Bomber crews were trained to fly B-17s and, later, B-24s at the Casper Army Air Base between 1942 and 1945—around 16,000 troops in all. They made a huge difference in Casper’s economy—and its social life. Wyoming State Archives.

Prisoner-of-war camps

Two major prisoner-of-war camps were located in Wyoming. Because government officials feared possible sabotage of coastal areas, shipyards, munition plants and other vital places, interior sites like Wyoming were considered good camp prospects.

A POW camp in Douglas, Wyo., was the largest in the state. Between 1943 and 1946, it included 180 buildings and housed up to 2,000 Italian and 3,000 German POWs, along with the 500 U.S. Army personnel acting as guards and administrators.

Fort D.A. Russell, located in Cheyenne, was established in 1867 to protect Union Pacific Railroad workers. In 1930, the name was changed to Fort Francis E. Warren.

During World War II, Fort Warren served as a training center for the Army Quartermaster Corps as well as a POW camp. It housed more than 900 German and Italian prisoners at a time.

Small agricultural and timbering operations around the state used POW labor. In fall 1943, for example, Italian prisoners harvested sugar beets near Pine Bluffs, Albin, Veteran and Worland; then beans, potatoes and hay.

“I found them working diligently, in a cheerful frame of mind, and they were literally a godsend to the farmers of Goshen County,” Gov. Lester C. Hunt observed, adding that the harvest could not have been completed without them.

Heart Mountain Relocation Center

On Feb. 19, 1942, President Franklin Roosevelt signed an executive order making it legal to remove people from designated military areas.

Accordingly, thousands of American citizens of Japanese ancestry were removed from the West Coast to the Heart Mountain Relocation Center near Cody, Wyo. In August 1942, the first Heart Mountain internees began arriving by train from California and Oregon. Two-thirds were Nisei, or American born. Heart Mountain was one of 10 such internment camps around the nation.

By 1943, Heart Mountain had nearly 11,000 residents, making it the third largest community in the state. Elected councilmen were appointed to committees on such matters as health and sanitation, food, resettlement and agriculture. There were schools and a weekly newspaper. A hospital with seven doctors and four dentists was opened, along with two movie theaters.

After Pearl Harbor, Japanese-Americans were exempted from the military draft. But in 1944, even while being detained, they became eligible again. The contradiction was not lost at Heart Mountain, where protestors formed the Heart Mountain Fair Play Committee. The group encouraged young Japanese-American men to avoid the draft until their civil rights status was clarified. During the war, 63 defendants were tried and convicted of draft evasion. Seven more members were subsequently prosecuted and sent to federal prison for conspiracy.

But others served with distinction in the Armed Forces and two received the Congressional Medal of Honor. Eleven Heart Mountain servicemen were killed during the war and 52 wounded.

In January 1945, the Sheridan Press commented, “The splendid record of the Nisei fighters who have gone from our concentration camps into the army might well serve to remind overzealous Americans that skin pigmentation in itself is not a badge of disloyalty.”

The last internees left the center on Nov. 10, 1945.
