“The last slaves were freed in the North.’
Partially true. When the XIII Amendment was ratified it freed the slaves in Kentucky and Delaware. It also freed the slaves in Tidewater Virginia, coastal North & South Carolina and 13 Parishes in Louisiana. These areas were under Union occupation on January 1 1963 and were exempted in the Emancipation Proclamation.
Should have read January 1 1863
The last slaves were freed in New Jersey.
