First Assault on Tokyo Settlement

Before the Battle
A few days after the SAZ Incident, Britannia is in panic because riots are breaking out in various places. Now that they are the largest armed group, the Black Knights draws the from the general publicand other rebels as the group sets its sight on Tokyo settlement. It is estimated that those who changed sides adds up to tens of thousands. Guildford refuses to let the soldiers' move because Cornelia has ordered them to make a perimeter. One of the generals try to point out that Cornelia has shut herself up in Euphemia's room due to shock. In addition to this, General Dalton has also gone missing sense the Riots began. Participants for Black Knights come from every area in Area 11. Realising the odds are against Britannian. Kallen hopes Ashford academy will not become a battleground in the impeding Battle however shortly afterward Zero takes it as the Black Knights main Headquarters. Meanwhile Cornelia orders the Glaston knights to be on alert,and that the army  form battle formations on the outer area of Tokyo settlement. She believes the rebellion will be subsided if they crush Zero and the Black Knights. In retrospect, Zero alerts his army that if they can defeat Cornelia, victory will be theirs. He then orders the army to follow the strategic arrangement of the battle and asks Diethard to watch over the command vessel. Zero Has Boarded Gawain, informing the Britannians that he'll begin his attack at precisely 00:00. He suggests that those who wish to surrender should go to his bases gate. The time right now is 23:57 and 00:00 is in less than 3 Minutes. Dalton refuses to back down, insisting on accompanying Cornelia despite the injuries he suffered. Before they set off, C.C warns Zero that this is the point of no return. As it is now, the fight won't end with just area 11. The entire world will be stained with the battle that Lelouch is about to engage in.

The Battle
Cornelia Li Britannia now has set up a perimeter around Tokyo Settlements outer areas looking at the Black Knights Charge toward the settlement when they suddenly stop. Zero orders that several Britannians Controlling plates all around the Tokyo Settlement Citadel release its support. They agree under the influence of Geass destroying thousands of Britannian Forces and subsequently kill themselves. Cornelia is shocked and can't believe the ground under her was all Purged. They then continue with the assault left and right destroying Britannian frames and picking off britannian long range support with a Raikou Cannon. However other Britannian forces closer to the citadel defend it and destroy some of the Black Knight Frames. Zero in Gawain with C.C. laughs uncontrollably on how he is about to win but then surprisingly gets attack by Jeremiah in the Siegfried they fight against the Knight Giga Fortress with limited success. In the meantime Kallen defends Ashford Academy against Britannians in the Guren. She and Ougi are alerted that the Avalon is in the Vicinity and has launched Lancelot and one Sutherland piloted by Cecile and Suzaku. Suzaku spare no time getting to the Raikou which Kallen attempts to stop him from doing Toudou is also getting ready to fight Guilford in the Zangetsu. Meanwhile Gawain temporarily defeats the Siegfried by shooting it into some buildings. Suzaku Destroys the Raikou with great success but soon as Suzaku sees Guren he charges at it taking no regard that he could get hit by its radiation Arm. He then tell Kallen how he will kill anyone in his way including her. they fight and she damages Lancelot quite a bit before the arm is destroyed by Suzaku he then goes on to slice off Gurens other arm and kick it off a building. After him Defeating Kallen he proceeds to Attack the Gawain which saved her. Lakshata is suprised to know Lloyd is in the Avalon something he makes a joke about, however Lancelot and Gawain are fighting each other with neither suffering damage until Lakshata deploys several Gefjun Disturbers disabling the Lancelot, However Zero Leaves to attack Cornelia.

The Citadel has almost been over run by Rebels and Gawain comes to Tokyo Settlements roof where Cornelia is waiting she fights Gawain along side Dalton. Eventually Zero uses his geass on dalton to fight against cornelia he shoots her, wounding her, Lelouch goes on to forcibly tear the Cockpit out of Cornelia's frame and destroy it. He also kills Dalton and uses his Geass on Cornelia to find the truth out about his mother. she tells him that she doesn't know anything about the murder but that Schneizel and the Emperor will definitely know he continues with the battle leaving a heavily injured Cornelia for dead.

Guilford still has his hands full with Toudou who he loses to and continues on fighting more Britannians. Soon afterwards Zero is told by C.C. that an unknown assailant has kidnapped Nunnally and taken her to Kamejima island. The two leave, something that scares everyone leaving Ougi in charge. However he is shot in the stomach by Viletta Nu when she regains her memory and is disgusted with the romantic relationship she had with an Eleven. Shortly afterwards she flees. Leaving no one in charge all the rebels go into a panic and interior conflict. The Britannians with whatever they have left take control of the situation and capture most of the Black Knights.

But during this operation Lakshata notices Nina Einstein in an ancient Ganymede equip with a nuclear bomb. Everyone attempts to convince Nina not to throw her life away and not to set the Sakuradite enhanced nuke off they fail in convincing her and she presses a button to set the bomb off telling Euphemia to wait for her in heaven. However the bomb fails and Lloyd arrests her ordering Ceciel to subdue her Knightmare and bring her to the Avalon. Briatannian Rule is once more over "Area 11".
