"Ulysses Grant was, first and foremost, the greatest Union hero of the Civil War."
Yep, the best the north had. He was well aware that the north had some 4-5 times the population of the south so he could afford to lose twice as many men in the field and still win fairly easily. Most of his "strategy" was to hammer straight ahead, knowing that when Lee ran out of lead, shot, powder and food he would lose. Worked too, lots of Union graves prove it. But, what the heck, they were just yankees, they still had lots more of them back up north, right?
