Quote #7
"To be a good soldier you must love the army. But to be a good officer you must be willing to order the death of the thing you love. That is… a very hard thing to do. No other profession requires it. That is one reason why there are so very few good officers. Although there are many good men." (3.3.114)
This is Lee talking. Although Lee is known for being a brilliant general, he was actually very aggressive; he wasn't afraid to send soldiers off to die. At the same time, he was apparently very concerned for his soldiers. For example, after Pickett's Charge (this is in the book, and it's also historically accurate), Lee rides beside his retreating soldiers telling them that it was all his fault.
Quote #8
He rode purposefully, slowly off into the dark feeling the swelling inside his chest like an unexploded bomb and in the back of his mind a vision of that gray rocky hill all spiked with guns, massed with blue troops at the top, and he knew as certainly as he had ever known anything as a soldier that the hill could not be taken, not any more, and a cold, metal, emotionless voice told him that coldly, calmly, speaking into his ear as if he had a companion with him utterly untouched by the rage, the war, a machine inside wholly unhurt, a metal mind that did not feel at all. (3.5.26)
Longstreet isn't susceptible to delusions—he knows when he's lost. Part of his brain is able to maintain distance and keep things in perspective. After losing Little Round Top to the Union (thanks partly to Chamberlain's men), Longstreet is convinced that the Confederates never get it back. Although Pickett's Charge hasn't happened yet, Longstreet recognizes that the battle might be over.
Quote #9
"God in Heaven," Longstreet said, and repeated it, "there's no strategy to this bloody war. What it is is old Napoleon and a hell of a lot of chivalry." (3.5.151)
Since Longstreet isn't into romanticizing the Southern Cause—he's no Gone with the Wind character—he thinks Lee's Napoleon-style tactics are flawed. He would rather fight a more defense-oriented war, instead of parading into the North and attempting to defeat the Union with one momentous battle. It's as if the South is living in the past, fighting a war in a style almost a hundred years old.
