Gold and Silver mined in California and Nevada were often part of the cargo going east as the Civil War consumed vast sums of money. Nearly all stage lines were heavily subsidized to carry the mail. After the American Civil War, Wells Fargo & Co. absorbed the Butterfield stage lines and ran stage coaches and freight wagons along the Central Route as well as developing the first agriculture in the Ruby Valley in Nevada to help support their livestock. The Army established Fort Ruby at the southern end of Ruby Valley in Nevada to protect travelers against marauding Indians along the road. The Army abandoned Camp Floyd in 1860 as the soldiers were reassigned back east to fight the Civil War.
