Earth Kingdom harbor

The Fire Nation Harbor is located in the southwestern part of the Earth Kingdom, and is where Zuko goes to have repairs on his ship after his first confrintation with the newly awakened Avatar Aang. The leading officer in charge of the Harbor was the newly appointed Commander Zhao, but it is probably under the command of another officer after Zhao left on his own mission to capture the Avatar. It seems that this harbor would be a stategic point since it is close enough to the Sounthern Water Tribe and it is a point where it can provide the Fire Nation Army with troops and supplies for their further push into the Earth Kingdom which would lead the the fall of Omashu.
