Actually we had the right history for May 20, it was on Tuesday (5/19) that we mistakenly ran the next day's history. Here's what should have run on May 19:
Explosion in Coal Creek, Tenn. kills 184 miners - 1902
Shootout in Matewan, W. Va. between striking union miners (led by Police Chief Sid Hatfield) and coal company agents. Ten died, including seven agents - 1920
The Steel Workers Organizing Committee, formed by the Congress of Industrial Organizations, formally becomes the United Steelworkers of America - 1942
31 dockworkers are killed, 350 workers and others are injured when four barges carrying 467 tons of ammunition blow up at South Amboy, New Jersey. They were loading mines that had been deemed unsafe by the Army and were being shipped to the Asian market for sale - 1950
