I remember all three
Especially Chamberlain....whose regiment was profiled in The Killer Angels....in Military History while in college we studied Gettysburg and was really moved by Chamberlain and his men.
Though I believe Chamberlain was just a Colonel at the time
Yes, Chamberlain was elected Col. by his volunteer regiment, and had to learn military tactics from a handbook along the way.
BTW, there is a phenomenal painting, I think called “Ghosts of Gettysburg?” or “Chamberlain at Gettysburg” about the reunion, showing an aged Chamberlain looking over Little Round Top as a ghostly battle takes place. I think Chamberlain died shortly after that reunion.
That’s true. Joshua Lawrence Chamberlain did not become a Brigadier General until almost a year later. At the end of the war, he was a Brevet Major General.
