Launching an attack with the intent of mutual destruction is clearly disadvantageous to the Feiyang Fleet, which is already at a numerical disadvantage. If the opponent withdraws, even with Hanfrey captive, Fatty would not be able to obtain his battleship. To ultimately exchange Hanfrey for a battleship, he must ensure Hanfrey continues to use the current Binart Fleet as his negotiating trump card and remains here.
The Hanfrey Fleet assuredly has an emergency plan for the capture of its commander. And the overarching principle of this plan is undoubtedly Hanfrey's safety. This presents an opportunity for Fatty.
As long as Hanfrey sees hope, he won't give up. Similarly, to gain negotiating leverage, he must keep the Hanfrey Fleet exerting pressure on the Fei Alliance Fleet. In this way, the initial problem of the bandit army delaying time, which could easily alert Hanfrey to imminent danger, becomes naturally resolved.
