...what feels like a startover!

Since I got that new book by Shannon D Smith (the Give Me Eighty Men one), the story feels like it has been started all over again. A lot of things have been reorganised and at the moment, I'm in the process of writing the different options for how Carrington can give the orders of December 21st, 1866 to Fetterman and/or Powell because here there seems to be a heck of a lot of confusion. For example, Carrington said he gave orders to Powell but Fetterman then claimed by rank to take out the detachment to relieve the wood train yet no other testimony (except from George Mackey and I don't really know who he was) backs this up. And on top of that, there are many other questions. For example, if it was possible to claim a detachment by rank then when didn't Powell claim Grummond's later command by rank? Or did he decline or refuse to take out the first detachment? And why hadn't Fetterman claimed command two days earlier when a relief force was sent out? Or were Carrington's orders actually different between the two days?
And on the subject of his orders, there is also the confusing issue with what he said to Grummond after Fetterman had exited the fort. Some people say he said to Grummond to 'remind' Fetterman of his orders and others say he said to Grummond to 'tell' Fetterman of his orders which are completely different things. And what are these orders? Some say they are the ones that say not to cross Lodge Trail Ridge but then why was Fetterman allowed to pass over it with no man going out to stop him? And why was he allowed to just go in the opposite direction to where the wood train he was meant to be relieving was? So does that mean the orders Grummond was meant to remind him/tell him of were different?
Very confusing. And there are other things too, including how the cavalry and infantry advanced, what happened where and when on the battlefield (and also back at the fort) and so on...
Also, some details of the original plan have been changed around and they have been compiled into a Add/Adjust/Lose list of what to do for the story. A big change is the circumstances of Fetterman and Brown's deaths and also Fetterman's whole personality.
Another thing is that before we were going from Carrington's testimony a lot of the times which is what many, many books afterwards draw information from. However, Carrington's testimony is full of what could be described as lies. He compiled it to make himself sound better, after a long time of being blamed for the disaster, and also to make Fetterman seem arrogant, disobedient and a bully, which, really, he wasn't.
So that's another change.
However, I have come up with a title for this book: 'Fighting With Their Eyes Closed: Braving The Storm at Fort Phil Kearny' which takes inspiration from what Grummond was alleged to have done in the incident on December 6th, 1866 when he was surrounded by Indians - fought his way out with his sabre with his eyes closed.
