You've got it exactly backwards. He 'freed' the slaves in those areas which were NOT under US control.
For example:
" Louisiana, (except the Parishes of St. Bernard, Plaquemines, Jefferson, St. John, St. Charles, St. James Ascension, Assumption, Terrebonne, Lafourche, St. Mary, St. Martin, and Orleans, including the City of New Orleans) ...irginia, (except the forty-eight counties designated as West Virginia, and also the counties of Berkley, Accomac, Northampton, Elizabeth City, York, Princess Ann, and Norfolk, including the cities of Norfolk and Portsmouth[)], and which excepted parts, are for the present, left precisely as if this proclamation were not issued. "

The emancipation was done to incite a slave revolt, which it didn’t. The only revolt it incited was in New York City, the infamous draft riots. I now return you to your regularly scheduled Civil War photo thread.
Actually he freed the “persons” who were slaves.
Persons NOT being “People.”
