Actually, 20 were hanged. 10 were hanged on the "Day of the Rope," June 21, 1877. Six hanged at Pottsville (James Carroll, James Roarity, Hugh McGehan, James Boyle, Thomas Munley, Thomas Duffy) and four at Mauch Chunk (Edward Kelly, Michael Doyle, Alexander Campbell, John Donahue) https://www.counterpunch.org/2007/06/21/the-day-of-the-rope/

Over the next 2 years, 10 more were executed, including Thomas Fisher, John "Black Jack" Kehoe, Patrick Hester, Peter McHugh, Patrick Tully, Peter McManus, Dennis Donnelly, Martin Bergan, James McDonnell and Charles Sharpe. https://en.wikipedia.org/wiki/Molly_Maguires

I was the one (6g) who after a quick search make the error of assuming 20 guys were not hung in one big event.

I knew many were killed and wounded and thousands (?) were greatly abused by low pay and over work and not to forget the bug one, 😬health, #blacklung disease 

Sorry, next time I will say, "I'm not sure" ...
