Why did Longstreet not want to go through with Lee's plan at Gettysburg? He thought the Union position was too strong.
He did not believe his men could get into position.
Longstreet did not know the terrain.
He did not believe Lee was a capable leader.

London includes a quote about john thornton as he is observing hal attempt to motivate the exhausted dogs "it was idle, he knew, to get between a fool and his folly". if the word "idle" is defined as "of no real worth, importance, or significance", what does this statement mean with regard to hal? who is the fool? what is hal's folly? why would john thornton think it of no real worth or useless to intervene?
