It sat beside him.

Medicine Crow later became known as one of the last people who could say that he had directly absorbed oral testimony from a participant in the Battle of the Little Bighorn.

This gave his later work as a historian unusual weight.

He did not simply inherit a story and repeat it unchanged.

He also pursued formal academic training, learned the methods of anthropology, and spent decades comparing oral memory with documents, landscapes, and institutional histories.

That combination — traditional knowledge and academic research — became one of the defining patterns of his life.

It began early.

His elders trained his body as well as his memory.
