As Wilf said , the book ,Bury my heart at wounded knee,by Dee Brown , is he definitive book on the subject , I would recommend going on google and listening to the speeches of chief Joseph , the good words speech ,or reading about the Bear creek massacre ,or chief Seattle,s reply to the government offer to buy the land ( in my opinion the greatest , most moving speech ever ), buy a Buffet st Maria album to listen to ,
The People ,,,were treated atrociously , you cant study the subject without being moved by the genocide that occurred , another stain on mans humanity .
