Not to sidetrack but my view on Picket's Charge was a lack of communications. The left flank attacked too early and the artillery ran out of ammunition and could not advance with and support the infantry- I think that as eager as Lee was to attack the center- if there had been a quick line of communication and all facts were present- he would have called off the attack.
I come from one of those divided families. As much as I admire the gallantry by much of the south I'm glad we are all still one country.
The Civil War- I blame the politicians in Washington (north and south) that didn't work together to get a peaceful solution. Their failure caused a lot of scars,
