Charles Cornwallis was defeated at the Battle of Yorktown.
The correct answer is A) Abolished slavery in the Confederacy.
The Emancipation Proclamation abolished slavery in the Confederacy. During the tough times of conflict and confrontation during the American Civil War, United States President Abraham Lincoln issued the Emancipation Proclamation on January 1, 1863. This was a very important moment in the history of the United States in that a US President proclaimed that all the slaves in the Confederate states were free.
The proclamation only was valid in the Confederated states that had seceded from the Union, and of course, it was not taken into consideration until many years after the war had ended.
