Shoshone Indians stand amidst the skin teepees (or &quot;lodges&quot;) they have erected at a camp somewhere in the Rockie Mountains circa 1860-1870. William Farnham of Bangor marched with California infantrymen in late January 1863 to attack a similar Shoshone camp along the Bear River in Washington Territory. In a letter to his parents, Farnham compared the battle to fighting Confederate troops back east.
