The two correct answers regarding the attack on the third day of the Battle of Gettysburg, known as Pickett's Charge, are:
- The attack failed and half of the Confederacy's men were either captured or killed.
- The Union retreated, giving the Confederacy strength and time to re-strategize.
(Note: While the first answer is correct, the second one is not; the Union did not retreat but held their ground. The Confederacy suffered significant losses during the attack. The first choice is definitively correct, while for the second, be cautious as it misrepresents the outcome of the battle.)
