Chapter 566

Chapter 565 is called "Assault".

Summary
As the Admirals doge the projectiles formed from the frozen mast, Luffy activates Gear Second, hoping to make a straight dash for Ace. However, Kizaru easily catches up to him and knocks him aside with a kick of light.

Up on the execution platform, the guards are about to execute Ace. However, they are blown back by an unknown force, which is revealed to be an attack by none other than Crocodile. While Sengoku wonders why Crocodile would aid his own enemy, the former Shichibukai notes that he only did it because he didn't want to see the Marines be satisfied. Suddenly, taking everyone by surprise, Crocodile's head comes flying off of his body. Doflamingo, standing behind Crocodile, says that he's jealous that he had decided to side with Whitebeard instead of him. Forming his head back onto his body, Crocodile responds that he isn't teaming up with anyone and attacks Doflamingo.

Meanwhile, Luffy has been knocked down, as Aokiji stabbed him with an ice saber. Hancock screams at Aokiji and prepares to interfere, but instead Marco knocks Aokiji away.

The pirates in the bay, attempting to make their way past the iron wall, all try to swim through the gateway made by Oars. As the Marines prepare to fire upon the susceptible pirates, a coated ship suddenly emerges from the sea, allowing most in the water to climb aboard. Whitebeard notes that he never said that all of his ships had surfaced. While the Marines are busy debating whether or not they should aim at Oars or the ship, Oars lifts the ship into the air and pulls it through the hole he created. As the pirates prepare to storm the stage, Oars takes cannon fire, causing him to collapse once more. Whitebeard then leaps into the plaza and, commanded his "children" to keep away, swings his Bisento in a circle, knocking away all of the Marines in his path.

With the only Marines still standing being the Admirals, a few of the Vice-Admirals, and those upon the podium, the Whitebeard Pirates prepare to make their final charge to save Ace. Sengoku then tells Garp that the two of them will be required to join the war.
