I will take this opportunity to note a particular letter of Cooper's to Hindman dated November 4, 1862 in which he bitterly complains to Hindman about Pike's attempts at undermining his command. He is writing this letter from his sick bed at the time but lays out some name places I had not heard of before relative to Watie protecting the Salt Works etc, and the fact that Pike has told many of Cooper's officers not to obey his orders. It would appear that this is the letter that sparks Pikes arrest by Hindman. The problem with the last paragraph of this letter is that it is styled in much the same manner as the Parks Order Book in that five lines are written in the space of one inch at the bottom of the page requiring out right interpretation of meaning. I will post this letter in a day or so after I make sure of a few parts I am yet not sure of.
I do not believe this letter can be found in the OR's or at least I haven't found it.
