Break Through !

After weeks of fruitlessly looking through testimonies, I finally think a type of break through has been reached. A few days ago I guess, I started writing down about 7 people's accounts of the events following up to and preceding December 21st, 1866, when the Fetterman massacre took place, and finally I'm coming across comparisons.
Some people were detailed and some a bit vague but overall, I think a Lieutenant named Wands and a Captain named Ten Eyck are our best bet to figuring it all out. They seem to have testimonies running parallel with each other, details perfectly matching up in some cases, and are very precise, which is always encouraged.
Other guys, namely a Captain named Powell, are the faultiest pieces of evidence I've come across so far, by a country mile. For example, he says that a relief party went out to relieve Fetterman at 9 o clock in the morning - even with disagreements on the time Fetterman exited the fort, that was way before everybody says he went out. So...
Powell *pushing to the front of the crowd gathered on the parade ground, eyes wide with excitement and pride*: Sir, Sir! I propose we send out a relief party immediately to ride to the aid of Brevet Lieutenant Colonel Fetterman! It is essential that we begin this with no time lost!
Fetterman *bemused*: I'm right here, Captain. A relief party for the aid of what?!
Hmm.
Very reliable, Mr Powell.
I know that a lot of Officers in the West at the time liked to make themselves bigger than they actually were but Powell is just incredible. He says he does things that he was nowhere near and, I'm not kidding, he says he was in control of the whole thing when that was glaringly obvious that that was the Colonel, Carrington's, job.
I think that he probably did this out of jealousy. He was one of the only Officers at the fort who liked Carrington and he probably wasn't very partial to how the others were treating the Colonel. Also, he was the one who got taken away from going out to relieve the wood train when Fetterman was placed in command. Interestingly, he doesn't mention this in his testimony, which I'm led to think is because of shame, possibly, and the fact that he is one of the older Officers there and younger Officers have higher ranks than him, and are being invited (OK, volunteering in this case) to do these jobs.
I don't know if he knew he was doing this because I get the impression that he was quite dreamy and lost in his own little perfect world where he was in charge of everything, so in that way, I feel quite sorry for him, but the fact that Carrington has made what seems like a billion corrections to his testimony speaks clearer than day that other people found out what he had said. I'm surprised he wasn't demoted because after all, his testimony was under oath.
Apart from that though (but I have to admit, I love reading Powell's testimony because of the sheer far fetchedness *if that's a word* of it all), I think I'm closer to sorting stuff out, which is a relief in itself.
It's a shame though that there isn't anything from Fetterman, Grummond and Brown - the main characters in this event - because I'd love to hear from them in some way of form.
