An eyewitness account can be found in the 1913-14 Biennial Report of the Bureau of Labor Statistics of the State of Colorado, available in our library. From a dispatch of the United Mine Workers of America, reprinted in the Biennial Report: "'One hundred and fifty gunmen, in militiamen's uniform and with state equipment, have, with six machine guns, kept up a constant attack on men, women and children since daybreak Monday morning. ... One boy, aged 11, was murdered by the gunmen when he ran to get a drink for his mother, who had lain in a cellar ill...the bodies of from fifteen to twenty men and women are lying on the prairie and in the ruins of the tent colony.'"
The Biennial Report also includes affadavits of striking miners, testimonies of state officials defending their actions, and even the texts of President Woodrow Wilson's proclamation, proposal for strike settlement, and appointment of a national Peace Commission in response to Ludlow. The Biennial Report represents an important collection of primary source documents in this event of national significance in the Labor Movement.
More resources and eyewitness accounts can be found in the newspapers of the time. See this post from the Colorado State Library's Yesterday's News Blog for local newspaper articles of the time. Additionally, the El Pueblo Museum, a property of History Colorado, is running a special exhibit, Children of Ludlow, through 2015. You can also visit the Ludlow site itself, in Las Animas County near Trinidad, which includes a memorial. The site is a National Historic Landmark.
