One of the most revered Indian chiefs in history has died — here’s his incredible life story

Joseph Medicine Crow, a renowned Native American chief and historian, died on Sunday at the age of 102.

Medicine Crow was the last living war chief of Montana's Crow tribe, a distinction he earned by accomplishing four traditional war tasks while serving in the US Army during World War II.

With his death, the US loses an invaluable historical resource — Medicine Crow was the last link to the famous Battle of Little Bighorn, also known as Custer's Last Stand.

In 2009, he was awarded the Medal of Freedom, and continued to speak on Crow history until his death. 

Here's Medicine Crow's unbelievable story:

Joe Medicine Crow was born on the Crow Indian reservation near Lodge Grass, Montana, in 1913.

Medicine Crow's step-grandfather, White Man Runs Him, was one of six scouts for George Armstrong Custer during the general's 1876 expedition against the Sioux and Northern Cheyenne.

The expedition culminated in the Battle of Little Bighorn in June of 1876.

The connection made Medicine Crow the last living person to have heard direct oral testimony from someone involved in the Battle of Little Bighorn.
