Copied from a history of George Henry Peterson found on FamilySearch.org, linked here.

In the spring of 1864, while [George Henry Peterson] was riding from Ogden, Utah, through the Weber Canyon, going to his home in Morgan County, near the Devil’s Gate he was surrounded by a band of about twenty-five Indian warriors. Having a pretty good understanding of the Indian language, Mr. Peterson asked them what they were going to do and their answer was that they were going to kill him. As quick as a flash he drew a 44-caliber Colt’s navy revolver from under his coat and “dropped it” on the Indian he took to be chief. This movement surprised the Indians to much that they left an opening the circle they had formed around him, of which the mules he was riding too advantage, and started through it on a gallop up the canyon, in the midst of a shower of bullets that went whizzing after him, none, however hitting him or his gallant rider, although one bullet went through the rim of Mr. Peterson’s hat. He says that the idea of drawing the gun on the chief came to him from reading of a similar occurrence in the adventures of Kit Carson in Old and New Mexico.
