Wouldn't it have made more sense for McLaws' Division to join the new Third Corps instead? IIRC, Longstreet wasn't a huge fan of McLaws anyway, and surely he'd prefer to keep his old division under his command, right? Did he suggest the transfer himself? That doesn't make much sense to me, seems like he'd be against it...if so, did he fight to keep Anderson's division under his command? If so, why was that request denied?
