Describe the Confederate soldiers' reaction to General Lee's appearance in The Killer Angels.

From the text:

The men yelled and whooped as he passed by. Many stopped and just smiled and some took off their hats. They had won again. The joy on their faces, the look of incredible pride, the way so many of them looked at him going by as if waiting for some sign of his approval of a job well done, another fight so nobly fought, lights in all the starry young eyes, and beyond that the way some of them had tears in their eyes as he went by, tears for him, for the cause, for the dead of the day; the sight of it was something very nearly unbearable, and he set his face and rode through saying nothing, nodding, touching his hat.
