In September 1879, four separate supply runs left Rawlins, Wyoming. The destination for each wagon was northern Colorado. The second wagon to leave had an unexpected passenger in the form of a puppy. One week after the departure of the freighters, U.S. Army troops gathered in Rawlins. Their orders would take them to the same territory as the supply trains. The White River Expedition was underway. The major leading the troops and the lively pup had no idea their lives were on target to collide in the harsh western landscape.
