Lincoln needed to announce it right after a big win for the Union. Antietam happened to be a well timed one.
Doing it after a big victory would help reinforce the fact that he was doing the right thing in the war, and that he was a good leader (good enough to be re-elected).
Announcing it right after a loss would be viewed as a weak, desperate move, and Lincoln couldn't afford that if he was to be running again for president.
Two things the GI Bill did for returning military personnel was giving them affordable education and providing affordable housing.
