NARRATIVE: Butch Cassidy and his gang carefully planned their robberies with great attention to detail, ensuring a quick getaway. They devised a brilliant plan, using fresh relay horses at various points along the escape route. For the Telluride robbery, they had gang members hold their first fresh mounts about a mile from the bank, then set up mounts further on the route at increasing distances as they got farther from the pursuing posse. A good horse can run forty miles per hour or even a little faster, but only for about one mile. The first exchange took place in under ten minutes after the heist. It took about 45 minutes to
form a posse, so by the time they began the chase, Butch and his Wild Bunch were at least ten miles ahead of them. With their carefully devised plan, the robbers could get eighty or ninety miles ahead of the posse in a day or so.

Bonnie and Clyde's getaway car was a stolen 1934 Ford Deluxe V8 with 85 horsepower. Butch and the boys had one horsepower, but they were very efficient with its use. (Source: "The True Story of an American Outlaw: Butch Cassidy" by Charles Leerhsen, Simon & Schuster 2020)
