I have the honor to report to you that from information received from various sources of the encampment of a large body of Indians on the Bear River, north of this point, who had murdered several miners, during the winter, passing to and from the settlements in this valley to the Bear River mines east of the Rocky Mountains. And being satisfied that they were part of the same band who had been murdering emigrants on the Overland Mail Route for the last 15 years, and the principal actors and leaders in the horrid massacre of the past summer. I determined, although the season was unfavorable to military expedition in consequence of cold weather and deep snow, to chastise them if possible.
