What heroic actions in the battle of Vicksburg?

Answer 1

At the Battle of Vicksburg a Confederate army under General John C. Pemberton surrendered to General Ulysses S. Grant after a campaign that had beun on March 29. The South lost 8000 killed and wounded; and more then 29,000 surrendered. Union casualties were 8910. This loss of manpower and control of the Mississippi River, atop the loss at Gettysburg, doomed the Confederacy.

about 90,000,1 met Lee at Gettysburg. Both armies felt that this was the place to fight.
Here one of the most important and decisive battles of the war took place. (Map, p.288.) Both sides fought with desperate courage. The Confederates held Seminary Ridge; the Union men, Cemetery Ridge, nearly opposite. The battle lasted three days (July 1-3, 1863). On the first day the Confederates gained the advantage. On the second day Lee's men made a rush to get Little Round Top, but were beaten back with heavy loss. Later, they got a foothold on Culp's Hill, but were soon driven out. On the third day Lee sent General Pickett, with a force of 15,000 Confederates to attack General Hancock on Cemetery Ridge.
In order to reach the ridge the Confederate force had to cross a mile of open ground. They came forward steadily, silently, under a terrible fire from the Union guns. Their ranks were plowed through and through with shot and shell, but the men did not falter.
