The Ludlow Massacre refers to the violent deaths of 19 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.
Despite attempts to suppress union activity, secret organizing by the UMWA continued in the years leading up to 1913. Eventually, the union presented a list of seven demands on behalf of the miners:
Recognition of the union as bargaining agent
An increase in tonnage rates (equivalent to a 10% wage increase)
Enforcement of the eight-hour work day law
Payment for "dead work" (laying track, timbering, handling impurities, etc.)
Weight-checkmen elected by the workers (to keep company weightmen honest)
The right to use any store, and choose their boarding houses and doctors
Strict enforcement of Colorado's laws (such as mine safety rules, abolition of scrip)
an end to the company guard system
The major coal companies rejected the demands and in September 1913, the UMWA called a strike. Those who went on strike were promptly evicted from their company homes, and they moved to tent villages prepared by the UMWA. The tents were built on wood platforms and furnished with cast iron stoves on land leased by the union in preparation for a strike.
The company hired the Baldwin-Felts Detective Agency to protect the new workers and harass the strikers.
Baldwin-Felts had a reputation for aggressive strike breaking. Agents shone searchlights on the tent villages at night and fired bullets into the tents at random, occasionally killing and maiming people. They used an improvised armored car, mounted with a machine gun the union called the "Death Special," to patrol the camp's perimeters. The steel-covered car was built in the CF&I plant in Pueblo, Colorado from the chassis of a large touring sedan. Frequent sniper attacks on the tent colonies drove the miners to dig pits beneath the tents where they and their families could be better protected.
On the morning of April 20, the day after Easter was celebrated by the many Greek immigrants at Ludlow, three Guardsmen appeared at the camp ordering the release of a man they claimed was being held against his will. This request prompted the camp leader, Louis Tikas, to meet with a local militia commander at the train station in Ludlow village, a half mile (0.8 km) from the colony. While this meeting was progressing, two companies of militia installed a machine gun on a ridge near the camp and took a position along a rail route about half a mile south of Ludlow. Anticipating trouble, Tikas ran back to the camp. The miners, fearing for the safety of their families, set out to flank the militia positions. A firefight soon broke out.
The fighting raged for the entire day. The militia was reinforced by non-uniformed mine guards later in the afternoon. At dusk, a passing freight train stopped on the tracks in front of the Guards' machine gun placements, allowing many of the miners and their families to escape to an outcrop of hills to the east called the "Black Hills." By 7:00 p.m., the camp was in flames, and the militia descended on it and began to search and loot the camp. Louis Tikas had remained in the camp the entire day and was still there when the fire started. Tikas and two other men were captured by the militia. Tikas and Lt. Karl Linderfelt, commander of one of two Guard companies, had confronted each other several times in the previous months. While two militiamen held Tikas, Linderfelt broke a rifle butt over his head. Tikas and the other two captured miners were later found shot dead. Their bodies lay along the Colorado and Southern tracks for three days in full view of passing trains. The militia officers refused to allow them to be moved until a local of a railway union demanded the bodies be taken away for burial.
During the battle, four women and eleven children had been hiding in a pit beneath one tent, where they were trapped when the tent above them was set on fire. Two of the women and all of the children suffocated. These deaths became a rallying cry for the UMWA, who called the incident the "Ludlow Massacre."
In response to the Ludlow massacre, the leaders of organized labor in Colorado issued a call to arms, urging union members to acquire "all the arms and ammunition legally available," and a large-scale guerrilla war ensued, lasting ten days. In Trinidad, Colorado, UMWA officials openly distributed arms and ammunition to strikers at union headquarters. 700 to 1,000 strikers "attacked mine after mine, driving off or killing the guards and setting fire to the buildings." At least fifty people, including those at Ludlow, were killed in ten days of fighting against mine guards and hundreds of militia reinforcements rushed back into the strike zone. The fighting ended only when US President Woodrow Wilson sent in Federal troops. The troops, who reported directly to Washington, DC, disarmed both sides, displacing and often arresting the militia in the process.
This conflict, called the Colorado Coalfield War, was the most violent labor conflict in US history; the reported death toll ranged from 69 in the Colorado government report to 199 in an investigation ordered by John D. Rockefeller, Jr.
