In 1877 the respected leader of the Nez Perce tribe surrendered to General Miles, acting on behalf of the U. S. Government.
At his surrender, Chief "Thunder Rolling Down the Mountain" (known to history by his Christian name "Chief Joseph"), had a 1 inch square clay tablet in a medicine bag/pouch hanging around his neck. The writing was unrecognizable to General Miles, so he asked Chief Joseph what it was? Thunder Rolling Down the Mountain told Miles that "the tablet had been passed down in his family for many generations, that they inherited it from their white ancestors... and that it was the title for the land where the General now stood."
The writing, which was translated by Dr. Robert D. Biggs, Assyyriology Professor at the University of Chicago, turned out to be a sales receipt dating back to 2042 B.C. in Assyria. It read:
Oddly enough, another tablet similar in size and appearance to The Chief Joseph tablet was found in 1963 in northwestern Georgia near the Chatahoochee River. This tablet was made of lead.
Like the Chief Joseph tablet, this one was also "a receipt for the sale of sheep and goats that were to be used in a ceremonial sacrifice". From information contained on the tablet, it appears to have been created in 2040 B.C.
The Nez Percé War of 1877. For five months a small band of 250 Nez Percé warriors, under the leadership of Chief Joseph, held off a U.S. force of 5,000 troops led by Gen. Oliver O. Howard, who tracked them through Idaho, Yellowstone Park, and Montana before they surrendered to Gen. Nelson A. Miles. During the campaign, more than 260 soldiers and more than 230 Nez Percé, including women and children, died. The tribe was then assigned to malarial country in Oklahoma rather than being returned to the Northwest as promised.
