Odessa

Odessa is an Eastern European city, located on the northern shore of the Black Sea. The city served as a large resource center for the Earth Federation with several mining facilities located around the city. During the One Year War Odessa became a focal point for both Federation and Zeon forces.

The city was captured on March 1, UC 0079 during the Principality of Zeon's first Earth Drop Operation. Once captured, it became a large source of much needed resources to Zeon. Odessa was put under the control of Captain M'Quve, who supervised the mining operations here. On November 7 Odessa became the target of a major Earth Federation counteroffensive aimed at retaking the city. Over the next two days, Federal Forces stage a blitzkrieg attack on the Zeon's defensive lines, breaking through and overwhelming them.

On November 9, Federal Forces penetrate the last of the Zeon Occupation Force's defensive lines, triggering an ultimatum from the Zeon commander M'Quve, demanding that Federal Forces withdraw or face a nuclear attack. It is said General Revil simply signals to his communications officers not to respond to M'Quve. Fleeing the battlefield with other top Zeon officials in the Zanzibar-class mobile cruiser Madagascar just before Federation forces break through their base, M'Quve launches a single nuclear missile, but it is successfully disarmed by Amuro Ray's RX-78-2 Gundam.

After the battle Odessa is fully liberated by federation forces, but not before Zeon forces were able to transfer a large amount of Odessa's resources into outer space for them to use. Remaining Zeon forces isolated on Earth eventually surrender, although some, such as Rear Admiral Yuri, find their way to other Zeon-occupied bases, where they escape into space.
