He was an amazing man. The fact that he was almost universally admired by the entire Union Army and its officers, despite him being the leader of their enemy in one of the most brutal conflicts in human history, highlights his incredible character.
Unfortunately, today we life in a thug society that holds General Lee up as a "rayciss!" Mention his name at any public or political speech today, and the liberals and the media will have you hung. I am not exaggerating.
Lee is almost certainly in heaven with his Savior, Jesus Christ. I am looking forward to meeting him.
They respected his cleverness and admired his ability, but I don't know that it really went deeper than that, especially when the bullets were flying.
I doubt Union soldiers fighting against Lee felt the kind of admiration for him that bound the Lee cult in the South together after the war. I'm not sure all Southerners felt that way when the war was still going on, either.
Rommel and Patton admired each other I guess, and troops in both armies had respect for the ability of the other side's commander, but it's possible to read more love and affection into that grudging respect for an adversary than is actually there.
