Relay teams on horseback begin delivering the first post as part of the Pony Express. The private enterprise consisted of over 80 riders and hundreds of stations along the east-west routes that stretched from St. Joseph, Missouri and Sacramento, California. While the Pony Express only operated for 18 months, during that time it was a success. With the incorporation of the Overland Telegraph Company of California and the Pacific Telegraph Company of Nebraska, the Pony Express' days were numbered.
