Cassidy and Longabaugh fled to New York City, feeling continuous pressure from the numerous law enforcement agencies pursuing them and seeing their gang falling apart. They departed from there to
Buenos Aires,
Argentina, aboard the British steamer
Herminius on February 20, 1901, along with Longabaugh's companion
Etta Place. Cassidy posed as James Ryan, Place's fictitious brother. They settled in a four-room log cabin on a ranch that they purchased on the east bank of the Rio Blanco near
Cholila, just east of the
Andes in
Chubut.
Bruce Chatwin's
In Patagonia references a letter Butch wrote from Cholila to
Elzy Lay's mother-in-law in Utah, dated August 10, 1902. The letter cites "our little family of 3" living in a 4-room house with 300 cattle, 1500 sheep, and 28 horses. Chatwin states the letter resides with the
Utah State Historical Society.
1905 Two English-speaking bandits held up the Banco de Tarapacá y Argentino in
Río Gallegos on February 14, 1905, south of Cholila near the
Strait of Magellan, and the pair vanished north across the Patagonian grasslands. The pair might have been Cassidy and Longabaugh. Fearing that law enforcement had located them, Cassidy and Longabaugh sold the Cholila ranch on May 1, 1905. The Pinkerton Agency had known their location for some time, but the snow and the hard winter of Patagonia had prevented their agent Frank Dimaio from making an arrest. Governor Julio Lezana issued an arrest warrant, but Sheriff Edward Humphreys, a Welsh-Argentine who was friendly with Cassidy and enamored of Place, tipped them off. The trio then fled north to
San Carlos de Bariloche, where they embarked on the steamer
Condor across
Nahuel Huapí Lake and into
Chile; they returned to Argentina by the end of the year. A man going under the name Frank Boyd, who was in reality Sundance/Longabaugh, killed a police officer on August 21, 1905, in a shootout at the port town of
Antofagasta, Chile. He was released on a bond (equivalent to
US$50,000 in 2022) and then, assisted by the US vice-consul in Antofagasta, fled to Argentina and finally Bolivia. This was not known until 2022, when the old Antofagasta
El Industrial newspaper was digitized. Cassidy, Longabaugh, Place, and an unknown male associate robbed the
Banco de la Nación Argentina branch in
Villa Mercedes,
San Luis Province on December 19, 1905, which is west of Buenos Aires, taking 12,000
pesos. They fled across the Andes to reach the safety of Chile. On June 30, 1906, Place decided that she had enough of life on the run, so Longabaugh took her back to
San Francisco. Cassidy obtained honest work under the alias James "Santiago" Maxwell at the Concordia Tin Mine in the Santa Vera Cruz range of the central Bolivian Andes, where Longabaugh joined him upon his return. Their main duties included guarding the company payroll. The two traveled to
Santa Cruz in late 1907, a frontier town in Bolivia's eastern savannah, still wanting to settle down as respectable ranchers. == Death ==
