Yes, I agree. To know them simply as great soldiers isn't enough. It's to know their religious beliefs; in their hearts, minds and souls, and how their beliefs changed, impacted and governed their lives as great godly men. You can read sooo much on how they affected people all around them especially Lee; both North and South and how dearly loved and respected they were.
Allow me to saw a few words for Gen. Lee. When war came and the Virginians celebrated, Lee took his family into their home and went into mourning. There was not a single day or night when Lee did not pray for the yankees. He held no bitter feelings at all against the yankees. He was a great peacemaker. He was great at helping confederate officers make peace with one another. One time after the war was over, he was attending a ball in Virginia and there was this yankee girl who attended too as well. But none of the southern boys and southern belles wanted anything to do with her and she was deeply hurt and left. Then she heard Gen. Lee's voice calling out to her who asked her to be his dancing partner and she accepted. When they got to the dance floor and danced, all eyes of the people was focused on them. When the song was over, all the southern boys wanted her and all the southern belles were jealous. The yankee girl ended up being queen of the ball. Wow, there are much more to share but wanted to share a few to let you all know he loved both North and South and wanted all to be united as Americans.
