Ferry Ordeal and Skyscraper Battle

'''The Ferry Ordeal and the Skyscraper Battle took place at the same time when most of the citizens of Gotham were evacuating the city.

The two ferries
Once the Joker had control of the city, he reported that if anyone is still in the city by nightfall, they will subject to his rule. However, he also warned the city of the bridges and the tunnels having explosives, which lead to the city taking two boats to escape, believing there would be no harm done there. The citizens were on one boat, and the criminals were on the other. However, the Joker revealed that there are two bombs on each boat and each boat has a detonator to the other. He gave them an ultimatum: if neither the citizens or the criminals blow the other up by midnight, the Joker will blow up both ships.

Battling the Joker's men
After Batman discovered the location of the Joker, he arrived at the Prewitt Building and began to attack who he believed were the thugs. However, he realised that the hostages were the Joker's men and the Joker's men were actually the hostages. The SWAT team eventually discovered this as well and started arresting the mob while Batman left to confront the Joker.

Final Confrontation
Upon meeting the Joker, he demands the location of the detonator, in which the Joker replies by letting The Chechen's vicious dogs off their leash and letting them attack Batman. Being pinned down, the Joker runs up to Batman and begins beating him with a pipe and is kicked away, but returns and attacks him again. He is again thrown off, and Batman (with his sonar-vision), tries to find the Joker, but is soon hit with the pipe and lands on the edge of the building, where the Joker pins him down again and waits for one of the boats to blow up. However, because neither the citizens and the criminals could bring themselves to do it, the Joker takes out his detonator and begins to press the button, but is about to give another story about his scars to Batman. Batman gains the upper hand and throws the Joker off the skyscraper, but is saved by Batman right before he hits the ground and is left hanging on a wire.
