Its hard to believe that after Antietam and especially Frericksburg, Lee believed that a mass Napoleon-style assault would work. That’s some stubborn thinking from an otherwise brilliant and innovative commander. After the first day, Longstreet wanted to side-step the Union army and get between it and Washington, forcing the Union troops be the ones to attack. Would probably have worked better. That was the basis of the post-war feud between them.
And Malvern Hill. And South Mountain. That was a big difference between Gran and Lee. Grant never made the same mistake twice.
Longstreet was correct, of course. The quality if Lee’s thinking as a commander deteriorated along with his decline in cardiovascular health during the war. Much of the post-war hostility against Longstreet was due to his embrace of reconciliation and Republican political loyalty.
It was military doctrine worldwide through 1918.
