I'm hoping the book will fill in the gaps. It's impossible the tell from the video how/why things evolved the way they did. For one, the steep terrain reported by the narrator cannot be seen. At 35 seconds into the recording, everyone seems to regroup at the bottom of the field of view, and Chapman moves alone up the slope. Was the main group pinned down where they were? Was the terrain such that only Chapman was able to move at first? How did he come to be left behind? I'm anxious to study further.
The first Medal of Honor "recorded" threw me at first. Jacob Parrott was the first to be awarded the Medal of Honor - for a mission in April 1862 behind enemy lines in Tennessee. Jacob Parrott was from Kenton Ohio, just a few minutes away from where I grew up.
