"The Wilderness-to-Petersburg campaign earned Grant the reputation of a plodding butcher who resorted to slaughterhouse tactics, knowing that even if he lost two men to every rebel, the North would still win. True, the campaign extracted a terrible toll: 64,000 Union and 30,000 Confederate casualties. But Grant did not want a head-on killing match. With skill and ingenuity he tried to flush Lee into the open, but subordinates poorly executed good orders, and Lee parried each thrust by waging a stolid defensive struggle, refusing to risk his dwindling manpower outside the protecting trenches. Although Grant did not destroy Lee, he pinned the Army of Northern Virginia down in the strategic arena. Unlike Pope or Hooker, Grant did not disengage and let Lee seize the initiative. Remorselessly and at great cost he prevented Lee from launching an offensive that could restore the strategic balance. Lincoln recognized this considerable achievement and urged Grant to "Hold on with a bull-dog grip, and chew and choke as much as possible.""
