Now you are giving General Lee and the ANV too much credit. It is much harder to win a battle on the offensive, especially when your army is out-manned, out-gunned and chronically short on supplies. There may be an appearance of Lee being on the offensive when he was actually playing rope a dope. And there was no shortage of dopes until Grant came along and showed a willingness to kill help Lee kill many more yankee soldiers. That is just what it took to win the War.
