Seven Days Battles
During the Seven Days Battles, Lee had eleven separate divisions under his command. Aside from the original core army that had been led by Johnston, there were assorted other commands from the Richmond area and North Carolina, as well as Jackson's Valley Army. The inexperience and poor coordination of the army led to the failure of Lee's plans to destroy the Army of the Potomac. As soon as the Seven Days Battles were over, Lee reorganized his army into two corps commanded by Jackson and Longstreet. He removed several generals who had turned in a less-than-inspiring performance in the Seven Days Battles, including John Magruder and Benjamin Huger.
