Lee favors offensive Napoleonic warfare tactics and despises defensive strategies. He also despises the use of paid spies. His command style is loose, which is good, as he trusts his men to execute their orders without him micromanaging. It is bad because his complete trust in his men results in disappointments, such as Stuart being out of touch with Lee for several critical days, leaving Lee blind in enemy territory.
Also, an invasion of this sort so far from home, with plans of such grand scale, requires tight control and flawless communication. Lee issues no written orders, some of his orders are confusing, and he never gets all his generals together in one place to coordinate planning. This lack of organization is a downfall, especially with new commanders in place after Jackson's death.
Lee's men hold him in high esteem. They view him as nearly a god and will do anything he asks. Even when the battle fails, his men do not blame him and are ready to fight some more.
Longstreet is important to Lee. He values Longstreet for his strength, experience, and friendship. With the death of Jackson, Lee looks for the company and support of a veteran commander he can depend on.
