That was certainly the long-standing plan of many regarding what to do with freed slaves.
But Lincoln's original idea was to offer freed slaves the opportunity to return "home" to Africa.
During the war, Lincoln talked with black leaders, and learned from them they wished to live here as free men, not move to Africa.
Lincoln understood and adopted their views.
So Lincoln made no efforts to force former slaves to move anywhere.
"The past is dead; let it bury its dead, its hopes, and its aspirations. Before you lies the future - a future full of golden promise, a future full of recompense for honorable endeavor, a future of expanding national glory, before which all the world shall stand amazed. Let me beseech you to lay aside all rancor, all bitter sectional feeling, and to take your places in the ranks of those who will bring about a consummation devoutly to be wished—a reunited country." - Jefferson Davis
In his second inaugural address, Lincoln also asked for unity:
"With malice toward none, with charity for all, with firmness in the right as God gives us to see the right, let us strive on to finish the work we are in, to bind up the nation's wounds, to care for him who shall have borne the battle and for his widow and his orphan, to do all which may achieve and cherish a just and lasting peace among ourselves and with all nations." - Abraham Lincoln
There's nothing left to fight about. Slavery is gone, gone for good!
