Than Khe, or Thôn Khe Xêng, is on highway 9 in Quang Tri Provence. It is located in northern Vietnam, about fifty miles from Nam Dinh. Than Khe was a smaller town rumored to have been a hiding area for the Viet Cong.
Chief Warrant Officer 2 Donald Wann, were found near Hill 1015, or Dong Tri Mountain, about six miles southwest of Thôn Khe Xêng in 2008.
Than Khe is frequently confused with Khe Sanh, which is located nearby. Khe Sanh is famous as the location where the US Marines defended a remote air base in a vicious and drawn-out battle. This was reportedly the only time Americans abandoned a combat base due to enemy pressure.
