Yes, Bob, the Curly story sounds more consistent with the generally accepted version of things, and you are correct I think in your id of the book and it's author. The programme was quite clear, however, about the 3 scouts that Curtis was getting information from and Curly was not among them. (Was Curly still alive in 1905?) Hairy Moccasin was one of the three and the the other two's names escape me at the mo. According to Curtis, he was told of Custer himself and his staff directly observing Reno's retreat and "could have ridden to his assistance within 5 minutes ride from the point of observation." The program eventually claims that then pres. TR persuaded him not to include this in his book, which he did not. An interesting twist I thought.
