Oh, they hated him. With an eye towards politics, he'd written a book that was very critical of his commanding general. There's a reason he was General Custer during the Civil War and Colonel Custer afterwards.
Fun fact, just before the battle, Custer had shaved his head. So, the traditional long blond hair we associate him with was not in evidence that day.
Many now believe Custer dies very, very early in the battle. One native american woman thought she saw two men helping a man with long blond hair late in the battle, but that couldn't have been Custer.
The descriptions of Custer's mutilations were given to Walter Camp by eyewitnesses. I guess it's possible they were lying and passing on something they'd heard through the grapevine but I don't have any real reason to doubt them.Not according to the accounts of the U.S. Army and the FN warriors. George Custer was surprisingly not mutilated/scalped. The stories of LCol Custer having been horrifically mutilated with an arrow being inserted into his genitals only started to arise well after the battle had passed into myth for both sides. The idea has been put forward that these stories were suppressed by the Army to spare Libby Custer, but given the rather lurid descriptions of the dead made by the press at the time and the corroboration by FN oral accounts that Custer wasn't mutilated would make that story not as believable.
It is possible that some confusion arose between descriptions of LCol George Custer, Maj Tom Custer and Lt Boston Custer, which seems more likely to me.
I don't believe Custer was recognized before, during, or after the battle, I would thus expect his body to suffer the same degree of mutilation as the others. Since the mutilations varied enormously from body to body, it wouldn't surprise me if Custer was spared mutilation or horribly mutilated, or anything in between. He didn't receive any special treatment one way or the other because he wasn't recognized.
I know that there are Indian accounts that claim Custer was recognized and his body was dealt with accordingly. Unfortunately, there are at least a half dozen contradictory accounts that cannot be reconciled. No matter what's the truth, the majority of the Indian accounts concerning Custer are either fabrications or honest mistakes.
Anyway, that's where I stand on this question right now. I know there are counter arguments and I'm open to being convinced to change my mind.
