If one were to say that Genie Kuangya personally led his most elite fighters to jump aboard the "Quintet" and take part in the battle, that would make a lot of sense.
The sudden appearance of the "Quintet" turned what was originally a certain victory into an extreme disadvantage. The surprise attack that damaged a destroyer and an escort ship tipped the scales of victory in the enemy's favor.
During the subsequent naval exchange of fire, the "Quintet" demonstrated formidable firepower as well as robust defenses.
To continue bombardment was more likely to end in disaster than success.
To win, they needed to think of another method.
They could forgo charging the energy shield and overload the weapons system, hoping for the entire fleet to make a concentrated, all-out assault and achieve a decisive victory.
