The Utah War, also known as the Utah Expedition or Buchanan's Blunder, was an armed dispute between Latter-day Saint ("Mormon") settlers in Utah Territory and the United States federal government. The confrontation lasted from May 1857 until July 1858. While not fully bloodless, the war consisted of no pitched battles and was ultimately resolved through negotiation. Nevertheless, according to historian William P. MacKinnon, the Utah War was America's "most extensive and expensive military undertaking during the period between the Mexican and Civil Wars, one that ultimately pitted nearly one-third of the US Army against what was arguably the nation's largest, most experienced militia."^[1]
