Legend of the Galactic Heroes: Die Neue These (Original Japanese Version)

In the year UC 798, or IC 489, the Iserlohn garrison fleet led by Admiral Attenborough encounters a huge Galactic Empire formation during a patrol mission in the Iserlohn Corridor.

Among the admirals under Reinhard's command, Wolfgang Mittermeyer and Oskar von Reuenthal have earned outstanding fame for their many achievements, and are commonly known as the Twin Pillars. The two are bound by a deep friendship.

Mittermeyer’s sense of justice has unleashed the wrath of Duke von Braunschweig, one of the most powerful men in the Empire. He may now be executed without going through military court. Fearing the worst, Reuenthal turns to Reinhard to save his friend.

After becoming the highest military and political figure, Reinhard starts to implement a series of major reforms, introducing a taxation system for the aristocracy and restoring freedom of speech. His policy creates both new hopes and great discontent.

The head of the Galactic Empire's Science and Technology Department, Anton Hilmer von Schaft, is a man known for his sheer ambition. He is now presenting to Reinhard a large-scale plan to retake the long-lost Iserlohn Fortress.

The planet Fezzan is an autonomous dominion located in one of the only two safely navigable zones that connect the Galactic Empire and the Free Planets Alliance.

Hilde has convinced Ernest Mecklinger to pay a visit to her cousin, Baron Kümmel. Prone to illness and forced to stay in bed, Kümmel is a man with a penchant for great historical figures, and he strongly admires Mecklinger.

A sudden recall order from the central government of the Free Planets Alliance forces Yang to head for the capital planet Heinessen. Yang assigns the command of the Iserlohn Fortress to Caselnes and von Schönkopf.

When the massive Geiersburg Fortress suddenly materializes in the Iserlohn Corridor, Caselnes immediately forwards a request for reinforcements to Heinessen, but now he must prepare for the imminent Imperial attack.

Admiral Kempff, Commander-in-Chief of the Geiersburg Imperial expeditionary force, sends a peremptory declaration of war to the Alliance garrison of Iserlohn. Then Geiersburg's main gun suddenly opens fire with devastating results.

The Imperial fleet relentlessly conducts their assault on the Iserlohn Corridor. As Caselnes is still struggling with organizing an effective resistance, Imperial armored infantry units have landed on Iserlohn, and threaten to establish a bridgehead.

An Alliance relief fleet is heading to the Iserlohn Corridor, but combat forces on the battlefield are limited, and a wrong move could turn fatal. Should the Iserlohn garrison fleet be unable to break the blockade, the reinforcements would be destroyed.
