6. The Hole in the Wall Gang was actually several criminal gangs
The Hole in the Wall Pass in Wyoming was an easily defended, difficult to approach hideout for several criminal gangs which took sanctuary there from the 1860s through the early twentieth century. Often several different gangs occupied it simultaneously, though they did not coordinate their various nefarious activities. The most famous of the gangs which used the pass was that known as the Wild Bunch, led by Robert Leroy Parker, also known as Butch Cassidy, and his partner Harry Longabaugh, known to history as the Sundance Kid. The Wild Bunch favored robbing trains, hoping to avoid shootouts in the aftermath of a robbery, and it has been falsely reported that during their career the gang never killed anyone in the course of one of their crimes. In reality, they killed several.
On September 19, 1900, members of the Wild Bunch entered the town of Winnemucca, Nevada. Three men entered the First National Bank and demanded that the cashier, George Nixon, open the safe and give up the gold coins within. After the cashier reluctantly complied the men made their escape with about $32,000, most of it in gold. They were pursued by a hastily formed posse, and later by Pinkertons, but they eluded the chase. It was later claimed that Butch Cassidy had been one of the robbers. He was not, but it was likely that the Sundance Kid was, and if so Cassidy certainly knew about the robbery, which took place as he was in Tipton, Wyoming, making plans for another train robbery. Butch and Sundance were alleged to have been killed in 1908 in South America, though their exact fate remains in question.
