With the Southern Pacific and Indian Ocean secured, ZAFT can proceed with their strategy to capture or destroy all mass drivers controlled by Earth Alliance. As part of this Earth-side offensive, a ZAFT task force left Carpentaria base heading for Mediterranean sea.

In May 25th C.E. 70, the ZAFT Task Force was intercepted by the Eurasian Federation’s Mediterranean fleet near Casablanca. However, the Eurasia Federation’s Mediterranean fleet was devastated by ZAFT’s aquatic mobile suits, including the newly developed Goohn.

With the defeat of the Eurasian Federation fleet, ZAFT task force entered into the Mediterranean sea. Soon they took control of the strategically vital Strait of Gibraltar, and began construction of Gibraltar Base.
