Battle of Eregin

The battle of Eregin was fought between the Galactic Empire and the Galactic Interplanetary Alliance, in 12 ADK. The battle was fought at the same time as the battles of Triton VII and Deviss. The battles were planned by the emperor, in order to bring war to the Alliance, and claim more territory for the small, relatively overlooked Galactic Empire.

The battle of Eregin was initiated after the emperors fleet came out of hyperspace above the world of Triton VII, which signalled the Imperial fleets under the command of Admiral Drast Rennis and Alenna Dressanni to begin their own attacks. Where Rennis had a passion for the dramatic, Dressanni was much more strategic, and fooled the Alliance defenders into believing that her force was smaller than it was, by most of her destroyers in a nebula above Eregin.

The planet was only moderately defended, both in space and on the ground, due to admiral Naz Arvages' ships being spread across several planets, in order to defend them from Imperial attack. However, most of Arvages' fleet had been stretched between Triton VII and Deviss, meaning only a few capital ships were available to defend the planet. Admiral Dressanis' fleet was therefore able to easily overwhelm the Alliance forces.

Prelude
The Imperials planned an attack on three planets in the outer rim, on the borders of Imperial-Alliance space. Three different task fleets were assigned to attack Deviss, Triton VII, and Eregin. Admiral Dressanni was assigned to the planet of Eregin. Due to the senate refusing to send admiral Naz Arvage reinforcements, Eregin, like Deviss, was lightly defended.

The space battle
The Imperial fleet came out of hyperspace simultaneously with the fleet under the command of admiral Rennis. admiral Dressanni orderered all but two of her destroyers and the Regent into a nearby nebula. This was a dangerous maneuver, as the nebula stripped the destroyers of their long range sensors.However, it also hid the destroyers from the sensors of the Alliance fleet.

As the Imperials advanced, so too did the GIA ships, aiming to destroy the three destroyers they could see, and the other ships, that already outnumbered the GIA fleet, but were weaker ship types than the pair of heavy cruisers in the center of the Alliances' line. T-wing fighters and TIE Seekers fought between the two fleets, although initially, the TIEs' were outnumbered.

Once the capital ships had closed, Dressanni gave the signal, a single cruiser entering the nebula. The Oppressor class cruiser was close enough to the destroyers that they could easily pick it up, both on sensors, and see it visually. The destroyers exited the nebula in attack formation, and flanked the Alliance vessels. The GIA ships clustered in an attempt to defend the heavy cruisers. This proved to be moderately succesful, destroying several cruisers and a star destroyer. Despite these losses, the entire Alliance fleet was crushed, allowing the Imperials to deploy  dropships to the surface.

The Battle
Imperial dropships deployed stormtroopers and Imperial regulars onto several battlefields on Eregin, where they were opposed by GIA ground forces. A few T-wings that had survived the fighting in orbit descended to the planet below, and performed strafing runs on Imperial ground troops. The Imperials set up anti-air batteries in order to combat the fighters, destroying them. The Imperial army advanced, capturing several strategic points, and calling in Stormhand hover tanks and all terrained maul transports.

The mechanical elements of the army quickly demolished bunkers and fortified positions set up by the Alliance troopers, which were being steadily pushed back. After several hours of heavy fighting in and around Eregins cities, the GIA forces were wiped out. Imperial troops quickly removed the Alliance governor from power, and the planet was declared under Imperial control.
