The Pony Express

In the spring of 1860, a rider mounted a horse in St. Joseph, Missouri, settled onto a mail sack resting on the saddle, and waited for a cannon blast. At 7:15 PM, the gun fired, and he galloped away into a cloud of dust. His destination was Sacramento, California, roughly 1,900 miles west. The founders of the new Pony Express had promised the trip would take about ten days. Many of their peers said it was impossible.

The long road to a short-lived service

The Pony Express operated for only 19 months, from April 1860 to October 1861, yet it became one of the most enduring images of the American West. To understand how the service came together, you have to start decades earlier, with the country's rapid expansion. In 1803, Thomas Jefferson purchased the Louisiana Territory from France for $15 million, doubling the size of the United States overnight. The following year, Meriwether Lewis and William Clark set out to explore the newly acquired land, covering roughly 8,000 miles over two years. What they saw—the land, waterways, animals, and native tribes—would shape the nation's future, though they could not have predicted how dramatically.
