History
This event stared off the Last Battalion soldiers attack London and trying to capture Integra Hellsing. Then Iscariot appears saving and capturing her from Millennium. Enrico Maxwell is promoted to Archbishop and leaves with his army of Papel Knights. Zorin Blitz is sent by the Major to kill Seras and her forces slaughtered the Wild Geese. Seras easily kills all of Zorin's soldiers but Seras herself is caught in Zorin's illusion and she is heavily wounded by Zorin and her scythe.

Dornez into a Vampire.

Integra was about to be captured by Iscariot forces until Seras comes in and Alucard returns to London with the eagle,he jumps from the building and joins the fight along with the other trump cards Alexander Anderson and The Captain.He is in Level Zero and summon his familiars easily wiped out all of the Vatican forces and some of Millennium's.Maxwell dies and Anderson goes off to fight Alucard and the two Clash Anderson is having trouble but was Saved by the remaining Iscariot forces and after getting past some ghouls Anderson goes up to face Alucard

Anderson uses the Nail of Helena to become a monster against Alucard. Anderson used his new powers to burn Alucard and his familiars on fire and Seras intervenes awaking her master from the monstrous Anderson.

Alucard, now awakened, transforms into his Cromwell form and launches his final attack against Anderson. While Anderson uses his thorns to burn Alucard and his familiars, Alucard pierces Anderson's chest and removes his heart and the nail.

After crushing both Anderson's heart and the attached nail, Alucard mourns Anderson's transformation saying that it reminds of himself when it happened to him 500 years ago Anderson gave him a words of Pity before he dies.

Then Walter now a vampire jumps from the air and crushes the remains of Anderson. Walter mocks Anderson saying that trash should not be mourned. Yumie, angered by Walter's disrespect, tries to kill Walter but is killed instead. Heinkel, who tries to save her, is shot in the cheek by the Captain.

Walter challenges Alucard to a duel While Integra and Seras go after the Major. Walter and Alucard begin their duel walter seems to have the upper hand but fails with his transformation and Alucard now has the advantage.Integra and Seras killing all of Millennium's forces and The Captain approaches. Integra leaves Seras to fight The Werewolf while she goes after the Major. Seras and The Captain begin their duel and Alucard (in his female form) begins to absorb the blood of everyone who died at London.

Captain becomes his Werewolf form and Seras is easily getting beaten. Pip who communicates with her gets back on her feet and fights back. Seras and Captain gave fatal blows to each other but Pip as Seras's familiar uses a silver tooth to kill the Werewolf.

After killing the Letzte Battalion forces manning the zeppelin, Integra arrived in the control room where the Major was waiting. Protected behind a wall of bulletproof glass, the Major told Integra that she was just in time to watch his final triumph over Alucard, who had just defeated Walter. As the vampire began absorbing all the blood in London, the Major patiently watched and waited, mocking Walter's last desperate attempt to kill Alucard. Musing that his nemesis had now gained millions of lives by absorbing blood, the Major explained to the distraught Walter that he was just another life sacrificed for his grand plan of destroying Alucard for good.

When Alucard finally finished absorbing the blood, the Major gleefully announced that he had won - moments later, Alucard began to disappear. Integra demanded to know what was happening, and the Major was more than happy to explain: Schrodinger had killed himself and fallen into the rivers of blood, allowing Alucard to absorb him and gain the power of "the self-observing Schrodinger's Cat". However, Schrodinger's powers relied on his ability to perceive himself as an individual; since Alucard had millions of souls within himself, he was unable to control his newly-gained powers. Before Integra and the Major's eyes, Alucard vanished into thin air as he became "a collection of imaginary numbers", neither alive nor dead.

With Alucard gone, his army annihilated, and the Deus Ex Machina falling apart around him, the Major calmly faced Integra Hellsing and challenged her to kill him, stating that she was destined to be his slayer as he was Alucard's. After killing the Captain, Seras joined Integra and attacked the Major with her Harkonnen cannon, but the powerful shots barely cracked the glass wall. The Major wryly lamented that the Doctor had done too good of a job, but became elated when Seras pulled an 88 mm flak cannon from the armory beneath them. This enormous gun proved strong enough to shatter the shield, hit the Major, and punch through the wall of the zeppelin in the process.

As the smoke cleared, the Major lay on the ground with most of his left side blown off, revealing his cyborg nature. Integra wondered if this meant he was a monster, but the Major insisted that he was still a human because he had retained his own will and mind - he claimed that his ability to defeat Alucard was proof of his humanity. Drawing a small pistol from his coat, he again challenged Integra, asking her to "make war" with him. He repeatedly fired at his advancing foe without success, but finally managed to shoot her in the left eye as she shot him in the forehead. Despite this, the Major died with a smile, happy that he had finally managed to shoot something. As the machinery sustaining his life ground to a halt, he gloated to Integra that he had achieved everything he had set out to do; he had finished his grand war and destroyed Alucard. Integra retorted that Alucard would return one day, as he refused to die at the hands of anything but a human - and for all his claims to the contrary, the Major was still a monster.

after math
the battle was over and  at the end Millennium proved to be a fool's dream as noun of the members survibes and thaw there leader the mager died without regrets, long-term events would prove that he and his followers had ultimately failed at all they sout out to acomplish. Far from being the seed of a world-consuming war, Millennium's attack on London was eventually classified as no more than a terrorist incident ("The Zeppelin Affair"). The city was rebuilt, and thaw both Hellsing and Iscariot where badly crippled they did survibe and would go on to regrouping and gradually restoring their strength. Even the Major's plan to defeat Alucard eventually proved futile - thirty years after his apparent "death", Alucard managed to return, having gained control of Schrodinger's powers by destroying all of the other souls within himself. for all they sacrifised there grand plane to kill alucard only mad him stronger then ever.
