....of the 1914 Ludlow mine massacre.

From wiki:

The Ludlow massacre refers to the violent deaths of 21 people during an
attack by the Colorado National Guard on a tent colony of 1,200 striking
coal miners and their families at Ludlow, Colorado on April 20, 1914.
The deaths occurred after a day-long fight between strikers and the
Guard. Two women and eleven children were asphyxiated and burned to
death. Three union leaders and two strikers were killed by gunfire,
along with one child, one passer-by, and one National Guardsman. In
response, the miners armed themselves and attacked dozens of mines,
destroying property and engaging in several skirmishes with the Colorado
National Guard.

This was the deadliest incident in the 14-month 1913-1914 southern
Colorado Coal Strike. The strike was organized by the United Mine
Workers of America (UMWA) against coal mining companies in Colorado. The
three largest companies involved were the Rockefeller family-owned
Colorado Fuel & Iron Company (CF&I), the Rocky Mountain Fuel Company
(RMF), and the Victor-American Fuel Company (VAF). Ludlow, located 12
miles (19 km) northwest of Trinidad, Colorado, is now a ghost town. The
massacre site is owned by the UMWA, which erected a granite monument in
memory of the miners and their families who died that day.

The Ludlow Tent Colony Site was designated a National Historic Landmark
on January 16, 2009, and dedicated on June 28, 2009. Modern
archeological investigation largely supports the strikers' reports of
the event.
