Thomas Eishen's book about Joshua Chamberlain at Gettysburg is entitled "Courage on Little Round Top".The author takes the reader into the minds and emotions of the men from both sides who fought at Little Round Top. As I shared each one's experiences and thoughts, I found myself caring deeply about each one,hoping for his success and well-being.Having brought the Confederate and Union soldiers to life so vividly,Mr. Eishen makes the human carnage of Little Round Top all the more devastating. One mourns for all those who did not survive it.
