Such a great number of outrages were committed in the anthracite coal regions by the Mollie Maguires on August 14, 1875, that the day came to be known as “Bloody Saturday.”
Early in the month symptoms of smouldering disorder began to increase in severity and numbers. The situation became so alarming that Superintendent Franklin, of the Philadelphia and Reading Company arranged to hold a meeting with the two great Pinkerton detectives, James McParlan and Captain Linden, who had been working for some time among the members of this outrageous organization of criminals.
This meeting was held at Glen Onoko, in the environs of Mauch Chunk. Here the three men cleverly managed to get together, and in the quiet shadows of the great hills, in that Switzerland of America, they fully discussed the situation and the work being performed.
It so happened that while they were returning from this meeting McParlan, otherwise James McKenna, as he was known to the Mollies, encountered some of the ringleaders of that organization: Alexander Campbell, Hugh McGehan, and others, all under suspicion for murder.
McParlan found himself in the position where it was necessary to accompany the Mollies to their homes, but he never was in their company very many minutes before he learned much of value to his chief, Allan Pinkerton. Captain Linden remained in Mauch Chunk, and Superintendent Franklin returned to Philadelphia.
B. F. Yost, a policeman of Tamaqua, had been cruelly murdered, July 6, and word had reached the detective that John P. Jones, of near Lansford, Carbon County, was marked as the next victim of the Mollies. He was murdered by James Kerrigan, Mike Doyle and Edward Kelly, September 3, following.
The Mollies sat together in the smoking car bound for the Summit. McParlan was under suspicion by the Mollies, and Linden had slipped into the car unobserved, ready at any moment to take the part of his brother detective, should he find himself in trouble. Nothing occurred to require his services and Captain Linden feigned to sleep the time away, until the drunken crowd left the car. Linden continued his journey to Tamaqua, and there awaited McParlan’s arrival.
Reaching Summit, Campbell pressed the detective to remain all night at his house, and he thought it best not to refuse and did so.
Campbell believed McParlan or McKenna as he knew him, had been in Mauch Chunk that day to obtain a new stock of counterfeit money, which he was supposed to be passing. McKenna had exchanged some money for crisp bills, but they were genuine. Campbell arranged with the detective for a supply of the “spurious” bills, to be delivered in the near future.
