Fort Yamhill (Polk County, Oregon)
Polk County · Oregon · Indian Wars
History & Significance
Fort Yamhill was established on March 26, 1856, during the Rogue River Indian War by Lt. William B. Hazen to watch over Indian tribes relocated from southern Oregon. A United States Military outpost operating from 1856 to 1866, it was located on the eastern border of the Grand Ronde Indian Reservation and its purpose was to protect and control Native Americans on the reservation.
The fort acted as a buffer and eased tensions between Native Americans and white settlers, while the army also policed the Native Americans on the reservation, enforced agency rules, suppressed inter-tribal disputes and returned escaped American Indians to the reservation. The outpost consisted of a wooden blockhouse, sentry box, barracks, officers' quarters, carpenter's shop, hospital, cook houses, blacksmith shop, tables, barn, sutler's store, and laundress quarters.
The regular army operated the fort from 1856–1861 and volunteer soldiers ran the garrison from 1861–1866. In late April 1856, Lt. Philip H. Sheridan (later a heroic Civil War general and General of the Army) arrived at Fort Yamhill to complete construction.
When the fort closed, the military auctioned off the buildings, many of which were taken apart for materials or moved. Two buildings from the fort exist today: the blockhouse, which was moved to Dayton in 1911, and an officer's quarters, which is at the park and under restoration.
Archaeologically, it is one of the best preserved forts in the Northwest from this period. Even though the buildings are gone, the "footprint" of the fort is still intact and beautifully preserved. Recent excavations have revealed building foundations, the kitchen fireplace, the bakery oven, as well as numerous military & domestic artifacts.
