Answer:
A. Gettysburg
C. Northern states wanted to secede
Explanation:
The Battle at Gettysburg was a massive failure for the Confederacy, since Robert E Lee planned to invade the North and end the war, but instead suffered an unrecoverable amount of casualties.
Northern states weren't the ones that wanted to secede- it was the Southern states states that felt Lincoln (or abolition) threatened their way of life.
