The main reason, IMO, the LBH is so studied (and restudied) is Custer (both George and Libbie). Fetterman lost 80 men in 1866 in what was probably the only real victory the plains tribes had against the government (it resulted in the closing of the Bozeman Trail), but it draws nowhere near as much attention. Why? Because Fetterman didn't have a beautiful, articulate wife who both wrote well and outlived most of the other participants in the engagement. There were a number of officers in the Seventh who had decided not to really talk about the battle until Libbie died...the problem is that she outlived them all.

And I'm still convinced that one of the reasons the Seventh came apart was the death or incapacitation of Custer early in the fight.
