By 1864, emigrants were attempting to use the route that would become known as the Bozeman Trail, though consistent Lakota pressure made the journey dangerous.

Every week shaved off the journey represented real savings in supplies, livestock, and time.

For a government still managing the aftermath of the Civil War and looking for ways to develop its western territories, a more direct road to the Montana goldfields was attractive policy.

What the road required was security.
