What was the total number of slaves freed when the Emancipation Proclamitation was ratified by all states effected?

The Emancipation Proclamation freed all American slaves except those in (1)

Maryland, Delaware, Missouri , Tennessee, and Kentucky; (2) the counties of Virginia that shortly thereafter became the State of West Virginia; (3) seven other specifically-named counties of Virginia; and (4) New Orleans and 13 specifically-named nearby Louisiana parishes.

These exceptions represented states and counties/parishes that were already substantially under Union control on January 1, 1863, the effective date of the Proclamation. By its terms, the Proclamation did not apply to slaves in those areas. Those slaves were freed, not by ratification of the Emancipation Proclamation, but by the adoption of the Thirteenth Amendment, which abolished slavery throughout the United States.
