As he took control of the states in rebellion, he would free all the slaves from there.
Explanation:
During the Civil War, Lincoln issued the Emancipation Proclamation, in which he stated that he would use his war powers to free all slaves in the Southern states that were in rebellion.
You have an incomplete question. We will answer how Lincoln
did the steps to emancipate slaves. Lincoln is against slavery in public and in
private. Although adamantly opposed to slavery, he first sought a slow death to
it. During the U.S Civil War, Lincoln first declared freedom to slaves in states
under rebellion to avoid antagonizing Border States that supports the Union,
and eventually freed all slaves.
