This site is reportedly about ten miles northwest of Hebron, in Thayer County. Kiowa served as a stop for both the Pony Express and for both the L. & P.P. Express Co. and C.O.C. & P.P. Express Co. stagecoaches. Jim Douglas managed the station operations.  Sources generally agree on the identity of this station.  http://www.nps.gov/parkhistory/online_books/poex/hrs/hrs4c.htm

Kiowa Station - Located seven miles northwest of Deshler, this site served as a stop for both the Pony Express and for both the Leavenworth & Pike's Peak Express Company and Central Overland California and Pike's Peak Express stagecoaches. Jim Douglas managed the station operations. Several settlers were killed in this vicinity during the 1864 Cheyenne and Lokota Sioux attacks along the Little Blue River. The site is situated in a farm field.

Between the old Kiowa Station and the Oak Grove Station are two sites where Indian attacks took place. About four miles west of the Kiowa Station, a marker designates the site of the Emery Stagecoach Ambush on the south side of the road. Here, a life-and-death race took place as a passenger-filled stagecoach was chased through the area by a war party on August 10, 1864. About 1.5 miles to the southwest is the site of the old Bowie Ranch. Here, a pioneer couple was slain in their home during the 1864 uprising. There are no remains of the ranch today. http://www.legendsofamerica.com/we-ponyexpressstations3.html
