Lee bushwhacked Grant but good. Think it was John Rawlings - Grant’s Aide - that said @ the end of the first day Grant broke down & cried. He’d never seen a “man come so unstrung”. Grant could be rightly considered the American equivalent of Russian General Georgi Zhukov, Josef Stalin’s top pick for battlefield command during World War II. Zhukov would pound German lines repeatedly- regardless of the cost whether it be in men or armored vehicles. He could’ve cared less. When you have an endless supply of manpower you tend to use them profligately.
