Going along with what
@Jamieva said, no one and I mean no could get along with AP Hill. Jackson was difficult at best and prone to court martialing people. Lee absolutely hated managing his corps commander's emotions yet they couldn't seem to manage themselves.
Hill and Longstreet were threatening to duel so Lee sends Hill over to Jackson in 1862.
Lee had the idea of putting AP Hill and Jackson together thinking they were both good and they would do even better together and that was a disaster.
If they can't manage themselves how can they grow and develop the supposedly more immature officers?
