My favorite Eastwood movie. It was taken from a book called Gone To Texas, by Forrest Carter. The only differences are the book doesn't have any of the 'Redlegs' stuff; his family isn't in the beginning, after the war is over Josie starts robbing banks, which is how the kid gets shot, and so there's no confrontation at the end. Other than that, many of the the scenes in the movie are literally word-for-word from the book, including the ones you mentioned, and:

"I wanna see that hand move slow as 'lasses."

"The only one who can sneak up on an indian is another indian."

Even the 'border shift' scene is right out of the book.
