I don't see how Stuart could be blamed anyway. It's not like Lee didn't have any other troops. Lee may not have learned the high ground had already been taken before he got there but he also knew he could not rely on one unit no matter how well they brought in information. You cannot 'sneak' an army of thousands into an area and not have someone notice.
I'm still trying to figure out why they were climbing a fence while under fire and no one thoguht to remove the fence post. Just doesn't make common sense. Neither did Picketts suicide charge. What a sad waste of humanity.
