Keeping the Eleventh Special Mixed Fleet in the Fan Flame Ocean, and even sending the repaired "Imperial Capital" along with four large carriers to attack Howay Islands?
It was plausible, but it required one precondition.
Strategic deception.
While discussing this issue with Liu Changxun, Bai Zhizhan repeatedly emphasized the need to find a way to divert the Newland Navy's attention.
There were ways, such as feigning an aggressive attack on Tuk Fortress.
Strategically, this demanded that the Empire's Navy be ready to advance into the Southwest East Ocean, or at least make the Newland Navy believe it.
Clearly, this was too difficult.
Not to mention anything else, the Empire's Army had already launched a strategic offensive in the northwest direction, and the Navy had to commit significant forces to push into Boss Bay.
Hence, even if it were possible to mobilize the Fleet, there wouldn't be enough forces to advance into the Southwest East Ocean.
