Commemorating the First World War Centennial in Kansas

The Occupation of Butte Montana

The onset of total war brought forth a critical need for copper, and the world economy was already facing a copper shortage due to the demand for electrical wire. The supply was tight and new production had been slow to come on line due to the high capital costs of finding and developing new mines. In 1914 the U.S. mines contributed 77% of the world’s copper, and about 31% of U.S. production was from Butte, Montana, which sat atop an ore body that was 50 to 80% copper, the richest in the world, and also contained important amounts of zinc, lead, manganese and molybdenum, all strategic metals as well.

Needless to say, the price of copper skyrocketed, going from 15.22 cents per pound in 1913 to a high of 27.2 cents per pound in 1916. After the U.S. entered the war in 1917 the price was fixed at 23.5 cents per pound. With production costs under 10 cents per pound the profits could truly be called extraordinary.

Going Under at Butte

The Butte mines were already running at capacity so the operators ramped up output by going deeper and putting on bigger work crews. Some shafts were lowered as much as a thousand feet, about 20% more miners were sent down and of course the shafts ran 24 hours a day. Maintenance and expansion work had to be done while running at high output.

This led to accidents. During the war at least 437 miners died underground in Butte. On June 8th, 1917 a fire caused by maintenance work in the Speculator Shaft killed at least 164 miners (some records say 169) in that shaft and the adjacent Granite Mountain Shaft, as they were connected at several levels. This accident was the worst ever in a non-coal mine in the U.S. and the fourth-worst in any kind of mine. Although there had been other accidents in Butte (for example, on October 9th, 1915 sixteen miners had died in the same Granite Mountain Shaft) the huge death toll stunned the community and even the nation.

Both shafts were badly damaged and several others also had to be shut down for a time due to carbon monoxide build-up. The mine owners encouraged speculation that the fire was an act of sabotage to limit production. The person suspected of starting the fire was a German immigrant named Ernst Sullau, but no evidence of a German plot was ever found. Organized labor never bought into this theory at all, feeling that the cause was the owner’s disregard for safety and a strike was called that further crippled production until the end of the year.

Due to minor disturbances, including anti-war protests by Irish and Hungarian miners, the state militia had already been called out in April to guard property and maintain order. Among them was my great-great uncle Sgt. Thomas J. Coberly, a 45 year old Butte tobacconist who had served in the Philippines during 1898-99.

After the Speculator disaster, it was decided that dealing with spies and strikes were way beyond the capabilities of citizen soldiers like Tom and regulars were needed instead, so elements of the 14th Infantry Regiment were pulled from Mexican Border service and rushed to Butte. In addition to responsibility for guarding mine properties, these regular army units were also tasked with ‘enforcing patriotism’.

As the strike continued, a leader of the Industrial Workers of the World named Frank Little came to town.  After a bombastic speech Little was murdered by persons unknown. Soldiers were among the suspects but no one was ever charged with the crime.

The federal occupation of Butte lasted until 1921. A Justice Department report later stated that ‘troops in Butte changed from a fair, restrained body of men to an unrestrained, vicious and violent body of men carrying on a veritable reign of terror’.

Other consequences of these events were also far-reaching. Sedition Acts were passed to prevent speeches like those delivered by Little and many labor leaders and socialists were subsequently arrested, including the prominent socialist Eugene V. Debs.

Production of copper in Butte never again reached the 1916 levels. A serious national shortage was averted by the rapid expansion of the Bingham Canyon pit in Utah, the beginning of the large-scale strip mining that many consider to be the greatest environmental disaster of the 20th century.

Did I mention that from January until September 1918 the troops in Butte were commanded by Capt. Omar N. Bradley, later to be Eisenhower’s right-hand man in WW2 and one of only five five-star generals ever in the U.S. Army ? Like Ike, he never got to the Western Front.

    Frank Little was brutally murdered. Dragged behind a vehicle and lynched. Can you tell me what “L.D.C.S.S.W.T” might stand for? They were on a sign pinned to Frank Little’s shorts.

    According to this site, the “L” on the note stood for Little.

    The other letters represented the first initial of the last names of other union leaders that the industry sympathizers or soldiers might target. Apparently, 3-7-77 was also inscribed on the sign, which is the measurement of grave (i.e., 3′ long, 7′ deep, and 77″ long). This number has significance in the vigilante history of Montana.

    I grew up in Butte. One of my grandfathers drove a cat that scooped the initial dirt from the Berkeley Pit, which is now a massive Super Fund site, where tax payers get to clean up industry’s mess. My other grandfather worked most of his life for copper mines, and my father worked in the mines from age 18-67, minus the times when labor attempted to get equitable wages for their work, and minus the times that the mines shut down to break the unions.

    Thanks for posting this interesting blog.
