This map covers portions of Oregon and Washington along the Columbia River and shows the routes of Captain Hall's Company of Oregon Volunteers who fought during the Cayuse War, the first of the Indian Wars in the Pacific Northwest. The war was instigated by the slaughter of 14 missionaries at Whitman Mission near Walla Walla, and lasted for nearly eight years until the Cayuse Indians were eventually defeated. The 20 pp. disbound report was issued by Captain Birkhimer more than forty years after the war ended, and is based largely upon survivor testimony of the events. The report text credits the information on the map to Colonel Thomas R. Cornelius, a pioneer who served extensively in the Indian Wars and for whom Cornelius, Oregon is named.
