Career
After George Armstrong Custer"s defeat, Wasu Maza followed Sitting Bulletin into exile in Canada and then back to South Dakota where he lived on the Cheyenne River Indian Reservation. Chief Iron Hail is often mistaken by historians for Chief Iron Tail, being Lakota contemporaries with similar sounding names. Most biographies incorrectly report that Chief Iron Tail fought in the Battle of the Little Bighorn and that his family was killed in 1890 at Wounded Knee, when in truth it was Chief Iron Hail who suffered the loss.
He and his family left the Cheyenne River Indian Reservation on December 23, 1890 with Spotted Elk and approximately 300 other Miniconjou and 38 Hunkpapa Lakota on a winter trek to the Pine Ridge Indian Reservation to avoid the perceived trouble which was anticipated in the wake of Sitting Bulletin"s murder at Standing Rock Indian Reservation.
He recounted his experiences in an in depth interview with Eli South. Ricker, for a book Ricker planned to write. In 1942 the Department of War annexed 341,725 acres (138,291 ha) of the reservation for use as an aerial gunnery and bombing range.
Beard"s family was among the 125 Lakota families uprooted from their homes. They were compensated by the government for their land in installments which were too low to enable them to afford more property, and as a result they both moved into a poor section of Rapid City.
When he died in 1955 at the age of ninety six, Dewey Beard was the last known Lakota survivor of the Battle of the Little Big Horn, and the last known Lakota survivor of the Wounded Knee Massacre.
