WORTHINGTON — A clay pipe linked to the U.S.-Dakota War of 1862 and considered sacred by Native Americans in Minnesota is being returned to the Sioux people after being sold at auction.

The Lower Sioux Indian Community unsuccessfully tried to stop the sale. Minnesota Public Radio reports the pipe was auctioned in Boston on Saturday for $40,000, nearly twice its estimated value.

Prairie Island Tribal Council President Shelley Buck says the buyer, who wishes to remain anonymous, wanted to return the relic, and that’s being arranged.

The pipe was a peace offering for a soldier from Sioux Chief White Dog, one of 38 Sioux hanged in Mankato on Dec. 26, 1862, for alleged war crimes.
