Avatar: The Last Airbender/Recap/Book 3/10 The Day of Black Sun Part 1

""I already failed the world once at Ba Sing Se; I won't let myself fail again.""

The day of the eclipse has arrived. The invasion party assembles, bringing back some old, familiar faces, and everyone prepares for the coming battle. Using submarines and tanks built by The Mechanist to infiltrate, the invasion is started: Aang heads to the capital to face Fire Lord Ozai, while the invasion force starts battling its way up the city docks and heads for the capital on foot, hoping to secure the defenses by the time the eclipse ends.
