big-deaf-role-in-history

There is a tale that goes on with the battle at the
Wounded Knee, an ugly confrontation between the Sioux
tribe and the American army. According to history books,
a Native American by the name of Black Coyote, who was
deaf, accidentally (or deliberately) set off his gun,
while the members the tribe were laying down their arms.

 
The gunshot triggered a massacre, that to this day,
remains ugly. There are questions:
1. Was Black Coyote really deaf?
2. Did Black Coyote deliberately or accidentally set off his
weapon?
3. Is it the first time, or was it Deaf Smith, that a deaf
person played a significant role in American history of the
19th century?
