Dublin

In part of the final stages of the First Neo Zeon War, to force the Federation to adhere to her demands, Haman Kan manuvered a colony into Earth Orbit. Her target was Dublin. Despite the attempts of the AEUG and Karaba, there was no way to halt it.

The leaders of the Federation in Dublin abandoned the city, sending no forces to help evacuate since they saw it as a means of population control. They were able to flee on private planes leaving thousands if not millions to die.

In response, the Argama and Karaba were sent to evacuate, with the Gundam Team covering. During the battle with the Neo Zeon forces under Glemy Toto, Karaba leader Hayato was killed in the fire fight with Neo Zeon Ace Rakan.

Ultimately, the evacuation was partially sucessful. There was no way of evacuating all the people in Dublin, but several thousand were able to survive after being put onto Karaba's flagship. When the colony dropped, it flattened everything in Dublin and created Earthquakes and Volcanic Eruptions all over the area. However, the area was spared the fate of Sydney Australia which had been destroyed in the One Year War, the colony didn't explode, it just fell apart and lessened the damage.
