Aside from the alarming tendency for the cartridge case to break and jam the action. A History Channel presentation on the battle claimed that large numbers of pen knives and pocket knives were found on the battlefield, indicating the soldiers were having to pry the cartridge cases out of their weapons.
I believe Major Reno documented this in an after-action report on the LBH. There may well have been a problem with the extraction mechanism. There was definitely a problem with training. An anxious trooper had a tendency toward more jams. I believe that it would have been better for thr Calvary to have the Henry or Winchester and the Infantry to have the Springfield.
