Lincoln's emancipation proclamation hoped to set all the slaves free, but what was the consequence?
not a single slave was freed
hundreds of slaves were freed.
all slaves from maryland were freed.
only slaves near antietam were freed.

Lincoln issued the preliminary Emancipation Proclamation, declaring that all slaves in the rebelling states would be free on January 1, 1863.

-Lincoln promised to relocate those blacks who wished to leave the United States, and he emphasized that no Federal assistance would be given to slave owners if their slaves rebelled or ran away.

~ However, the Emancipation Proclamation claiming that slaves "henceforward shall be free" did not set one slave free, nor did it shorten the war as Lincoln had hoped.

so your answer would be the first one: not a single slave was freed
