The Siege of the North

"The Siege of the North" is the 2-part season finale to the first season of Avatar: The Last Airbender, originally aired as a 1-hour special on December 2, 2005.
==Summary==
===Part 1===
As the Fire Nation's forces close in on the Northern Water Tribe, the leaders and citizens scramble to find a way to defend against the armada. As night begins to fall, Admiral Zhao decides to heed Iroh's advice and halt the attack since waterbenders are stronger under the moonlight. Zuko leaves Zhao's ship and infiltrates the tribe on his own, seeking to capture Aang. Aang believes going into the spirit world and speaking to the moon and ocean spirits could give him the wisdom to defeat the Fire Nation. However, after Aang's spirit leaves for the spirit world, Zuko manages to kidnap his body.
===Part 2===
Zuko struggles to find shelter in the freezing temperatures of the North Pole, while Sokka, Katara and Yue search for him and Aang. At the Northern Water Tribe, firebenders and Fire Nation tanks manage to infiltrate the city. Admiral Zhao slays the moon spirit, Tui, and the waterbenders lose their ability to waterbend. In anger, Aang, who along with Zuko was rescued by Sokka, Katara and Yue, goes into the Avatar State and destroys the entire Fire Nation armada and army, with the exceptions of Iroh and Zuko. Yue, who was imbued with some of the energy of the Moon spirit when she was a baby, sacrifices her life to revive it, and becomes the Moon spirit. Meanwhile, angered by Iroh's betrayal and Zuko's failure, Ozai gives his daughter, Azula an undisclosed task.
