Depends...if by "without Batman", you mean that Bruce Wayne never became Batman, the mob would have retained control of Gotham until the League of Shadows destroyed the city.
If you meant that Bruce Wayne never returned to Gotham after he cancelled his energy project, perhaps he moved on and moved somewhere else, well, I think that it would have ended the same, maybe with Bruce Wayne's death.
This is because part of Talia's revenge is to make Bruce watch his city get destroyed, so she would have hunted him down and captured him, and probably would have him put in the same prison. Then, him being Batman and all, he would have managed to escape and save Gotham just in the nick of time, because he's Batman.
