Answer:
C
Step-by-step explanation:
In severe fighting, the Confederates swept the Federals from the fields west and north of town but were unable to secure Cemetery Hill and Culp's Hill to the south. The following day, as reinforcements arrived on both sides, Lee attacked the Federals all along their line but failed to dislodge the defenders. On July 3, Lee attacked the Union center on Cemetery Ridge and was repulsed with heavy losses in what is now known as Pickett’s Charge. Lee's second invasion of the North had failed and had resulted in an estimated 51,000 casualties on both sides, the bloodiest single battle of the entire war.
