In 1865, General John Bidwell backed a petition from settlers at Red Bluff, California to protect Red Bluff's trail to the Owhyhee Mines of Idaho. The U.S. Army commissioned seven forts for this purpose, and dispatched a Major Williamson in April to explore a site for a fort in either Goose Lake Valley or Surprise Valley, from which he selected a site near Fandango Pass at the base of the Warner Mountains in the north end of Surprise Valley, and orders to build the fort were issued on June 10, 1865. Although Surprise Valley settlers desired Army protection, ranchers dispossessed of lands for the fort complained, and claimed damages from the Army.
