The Wisconsin prairie that became the world’s biggest ammunition factory overnight

FDR’s Massive Baraboo Ammunition Plant Transforms Wisconsin

Just weeks before Pearl Harbor, FDR set a plan in motion that would change Wisconsin forever. The Army seized 79 farms near Baraboo, forcing families to leave by March 1942.

Soon after, 11,000 workers swarmed the site, building the world’s largest ammo plant in mere months.

They laid 24 miles of railroad, built housing for thousands, and even created Badger Village with schools, childcare, and hospitals. By May 1943, the first trainload of powder for M-1 rifles rolled out.

The sprawling Badger Ordnance Works now stands as a testament to America’s wartime might, with its museum preserving stories of the workers who made it all happen.

Roosevelt Approved a Huge War Factory in Wisconsin

On November 19, 1941, President Roosevelt gave the go-ahead for a $65 million factory near Baraboo, Wisconsin. The government picked Sauk Prairie because it was far from coasts that enemies might attack.

This happened just weeks before Pearl Harbor pulled America into World War II.

The Army liked the spot for its train connections and the Wisconsin River, making it easy to bring in materials and ship out bullets to troops.

Families Lost Their Farms in a Flash

The Army took over 10,500 acres of good Wisconsin farmland, forcing 79 farm families to leave. Many farms had stayed in families for many years.

The government told everyone to be out by March 1, 1942, no matter how long they’d worked the land. Some had less than three months to find new homes and sell animals and tools for very little money.

The winter weather made moving even harder as farmers watched bulldozers roll onto their land.

From Barns to Barracks Super Fast

Workers knocked down 715 farm buildings across the big site. They kept only 85 buildings to house the first workers.

Old barns, silos, and farmhouses came down as crews worked day and night. The land changed completely in weeks as old oak trees fell and farm fields got flattened.

By early 1942, the country setting looked more like a factory zone as workers got the ground ready for America’s biggest bullet plant.

An Army of Workers Built a City From Nothing

Building started in March 1942 with more workers than anyone thought.

By summer, 11,000 construction workers filled the site – carpenters, electricians, plumbers, and workers from every job type.

They came from Chicago, Milwaukee, and small towns all over, drawn by good pay and a chance to help win the war. The site buzzed with activity all day and night as crews raced to finish on time.

The Plant Grew Faster Than Anyone Expected

Workers finished 900 buildings by December 1942, less than a year after starting. They put down 24 miles of train tracks across the site to move stuff between buildings.

The plant had huge areas for making gunpowder and rocket fuel, plus water plants, power stations, and storage bunkers. Teams built roads, laid miles of pipe, and set up electrical systems.

The building speed shocked even military planners who pushed for quick work.

Workers Needed Places to Stay – Right Away

Housing went up almost as fast as the factory buildings. The government built sleeping quarters for 12,000 construction workers on site.

As production workers came, more housing went up for another 4,000-8,000 workers and their families. What started as short-term housing grew into real neighborhoods with streets, sidewalks, and water.

Many workers moved hundreds of miles, creating a new community where none existed before.

A Full Town Grew Across the Highway

Badger Village took shape across from the main plant.

This wasn’t just housing, but a complete community with schools, stores, and everything families needed. The village had its own fun center, hospital, and many cafeterias.

Parents could leave kids at the 24-hour childcare center before going to work. Buses ran all day and night, taking workers to and from the plant.

The village became home to thousands who came to Wisconsin to help win the war.

The Factory Started Its Machines

Chemical production began in January 1943, just 14 months after Roosevelt signed the papers. Workers mixed dangerous chemicals and ran complex machines to make the fuel needed for bullets and rockets.

Safety rules were strict since one spark could cause a huge explosion.

Training happened while working since many had never seen factory equipment before coming to Badger. The plant quickly made more and more as fighting got worse overseas.

The First Bullets Headed to War

On May 10, 1943, the first train of finished products left the Badger plant.

That shipment carried 60,000 pounds of gunpowder headed for the Twin Cities Ordnance Plant, where workers would put it into M-1 rifle bullets.

Those bullets soon reached American soldiers fighting in North Africa and getting ready to attack Europe.

The plant kept sending steady shipments after that first train left, making more each month as more workers joined.

Women Ran the Production Lines

Women made up nearly half the Badger workforce by 1945. They did jobs people thought were "too dangerous" or "too technical" for women.

Women ran chemical mixers, tested fuel batches, and worked heavy machines throughout the plant. They worked all shifts, often taking care of family duties along with their jobs.

Many had never worked outside home before the war but quickly showed they could handle the tough work.

The Plant Served America Through Three Wars

Badger Ordnance Works kept producing ammunition long after World War II ended.

The plant made propellants for the Korean War in the 1950s and ramped up again during Vietnam in the 1960s and 70s. Over 33 years of active operations, more than 23,000 people worked at the facility.

The plant finally closed in 1998 after the Cold War ended.

Today, the massive site stands as a reminder of how quickly America converted from a peacetime economy to the arsenal of democracy when war came calling.
