In the emancipation proclamation Lincoln does not mention Delaware Kentucky Maryland and Missouri.these states had slaves but were not part of the confederacy .what happen slaves in these states?

In the Emancipation Proclamation, President Lincoln focused on freeing enslaved people in Confederate states, as it was a strategic wartime measure aimed at weakening the South. Delaware, Kentucky, Maryland, and Missouri, being border states loyal to the Union, were not included in the proclamation. As a result, slavery continued in these states until the passage of the Thirteenth Amendment in December 1865, which abolished slavery nationwide. While some enslaved individuals in these border states escaped or were freed through local actions, the official end of slavery only came with the amendment.
