 Grant had 108,000 men and threw them straight at Lee, whose 59,000 men were well entrenched. In the first hour, and some say even within the first 20 minutes, 7,000 of Grant's men were killed or wounded, with the Union attack repulsed and nothing gained. But the bad news went on for many more weeks. At one point, Grant had lost more than 40,000 men in 30 days, and that figure grew to his having lost 60,000 men in 45 days.
