The Emancipation Proclamation was issued in Washington, DC, by President Lincoln, and freed those slaves held in territory then in rebellion against the government of the United States of America. As a result, it did not free anyone until Confederate lands were conquered after the Proclamation was signed. Those slaves held in lands already under the control of Union forces were not affected by the Proclamation.
Emancipation Proclamation - declared slaves free in the any area still in rebellion on the date the final proclamation was issued (January 1, 1863). Note that Lincoln took this step under his "war powers" as Commander-in-Chief; he did not have the Constitutional authority to free them elsewhere (though he took other steps to accomplish that as well). - authorized the armed services to accept blacks
The Emancipation Proclamation abolished slavery in the states that were not under Union control. Although not many slaves were actually freed, it did give black men the freedom to joinand be accepted into the armed forces. The major message that came from the speech was that the civil war was being fought for freedom.
