Battle of Blair Mountainhttp://en.wikipedia.org/wiki/Battle_of_Blair_MountainThe Battle of Blair Mountain was the largest open class war in United States history and was the second largest overall armed insurrection next to the American Civil War.
For five days in late August and early September 1921, in Logan County, West Virginia, between 10,000 and 15,000 coal miners confronted an army of police and strikebreakers backed by coal operators in an effort to unionize the southwestern West Virginia coalfields. Their struggle ended only after approximately one million rounds were fired,<1> and the United States Army intervened by presidential order.
By August 29, battle was fully joined. Chafin's men, though outnumbered, had the advantage of higher positions and better weaponry. Private planes were hired to drop homemade bombs on the miners. A combination of gas and explosive bombs left over from the fighting in World War I were dropped in several locations near the towns of Jeffery, Sharples and Blair. At least one did not explode and was recovered by the miners; it was used months later to great effect during treason and murder trials following the battle. On orders from the famous General Billy Mitchell, Army bombers from Maryland were also used for aerial survaillance, a rare example of Air Power being used by the federal government against US citizens.
Following the battle, 985 miners were indicted for murder, conspiracy to commit murder, accessory to murder, and treason against the State of West Virginia. Though some were acquitted by sympathetic juries, many were also imprisoned for a number of years, though they were paroled in 1925. It would be Bill Blizzard's trial where the unexploded bomb was used as evidence of the government and companies' brutality, and ultimately resulted in his acquittal.
