The South came very close to winning the first two days.

Explanation:

General Lee had come so close to winning the day before that he sent Pickett and his men on a charge( known as Pickett's Charge). The union open fired on the charge and then New York, Ohio, and Vermont regiments flanked them on both sides. Most of the confederates were wiped out. Including 2/3 of Pickett's division.
