"Sundance and The Wild Bunch Hit the Union Pacific"
Greg Kelsey

The Sundance Kid and the Wild Bunch robbed the Union Pacific Overland Flyer No.1 in the early hours of June 2, 1899 near Wilcox, Wyoming.  The outlaws used careful planning and dynamite - lots of dynamite.
They first used dynamite to disable a trestle, isolating a portion of the train.  Next, dynamite on the door of the mail car.  Likewise, they used a couple of sticks to blow the door of the Express car.  Finally, they used several sticks to open the safe.  In doing so, the blew the Express car to smithereens, scattering bits of wood and metal, as well as bank notes, cash, jewelry and other valuables.
They gathered up the strewn bank notes and headed for the Hole-in-the-Wall hideout, carrying and estimated $30,000 - $50,000 in valuables.
