alfa6: "Picket’s Charge was to have taken place in conjunction with an attack by Stuart’s Calvary."

There were to have been simultaneous attacks by:

1. Picket in the center.
2. Ewell in the north, to take Culp's Hill.
3. Stuart from behind to cut off Union retreat.
4. Support and follow-up by Longstreet in the South.

That every attack failed is blamed by Lee's admirers on his subordinates, especially ultimately, future Republican Longstreet, and by Lee-skeptics it's blamed on, among other reasons, Lee's woefully inadequate staff.

Of course, we always hear that Pickett never forgave Lee. Many years later Pickett was asked why he thought the charge failed. His response was, “I think the Yankees had a lot to do with it.”
