Here is a copy of Sgt. Flanagan's obituary as published in the Mandan Daily Pioneer on April 23, 1921. In this obituary, Flanagan is claimed to have been a messenger sent to Reno's battalion shortly after it separated from Custer's 5 troops. He claims it was the only thing that saved his life that day. For this to have occurred, Flanagan had to have been assigned to Custer's HQ's escort.
"The more I see of movement here (Little Big Horn Battlefield), the more I have admiration for Custer, and I am satisfied his like will not be found very soon again.”
~ Gen. Nelson Miles, Commanding General of the Army ------
"With our cherished ones deliverance within our grasp we waited breathless two hours, for the order that never came."
