Cassio Tagge finally decided to attack Dawn Star Planet!
This was not an irrational decision. On the contrary, from his perspective, it was the optimal solution to the current predicament.
The prerequisite for this large-scale military operation to raid the Modell Sector was surprise. But in reality, once they arrived at Annaj Planet and saw the defensive facilities and fleet waiting in full readiness, the so-called surprise attack no longer existed.
The Separatists had been prepared all along.
The next step was to force an assault on Annaj Planet. But first, the Archangel of Death personally took the field and, from the very start of the battle, beat the vanguard until they screamed for reinforcements. Only after Jan Drouga and Sa Kuis, two Dark Side powerhouses from the Hand of the Chancellor, intervened did they barely manage to halt the Archangel of Death's slaughter.
Then, in the fleet battle, they were met head-on by the enemy's advanced Calamity-class battlecruisers and Hell-Angel Class Battlecruisers, and their progress was painfully slow.
In the end, they had no choice but to concentrate their firepower and heavily damage the space station before forcing a landing.
Yet they suffered repeated setbacks in the ground battle as well. The widespread appearance of biological weapons turned urban street fighting into a nightmare for the Republic clone army. While those weapons could not contend with the Republic army's armored forces in open-field battles, in an urban combat environment, biological weapons were indeed capable of inflicting devastating casualties on the Republic army.
Thus, after more than half a month of fighting, this operation could already be considered a failure.
Even if he truly captured Annaj Planet and turned it into a forward base, even if he successfully completed the construction of the Hyperspace Stabilizer and established a stable route
