James Longstreet commanded the other corps of Lee's army. He is described as a somber, quiet man, whose four children had died of a fever shortly after the war began, but he continues fighting even so.
In reality, Longstreet is Jackson's superior.The two commaders have about the same number of troops, and Lee gives similar value to their advice. Longstreet is seen to be more cautious than Jackson, but he is considered an excellent commander. Before the Battle of Chancellorsville, Lee sends Lonstreet further south to deal with Union threats in the Carolinas. Thus, he is not present at the great battle.
