What does the naval term "No Quarter" imply?

The term "No Quarter" implies a fight to the death, indicating that no mercy will be given to the enemy, and surrender would not be an option. This naval term has its roots in maritime warfare, where showing "no quarter" means that if an opposing force is defeated, they will not be spared or offered safe passage. Instead, those who are captured in battle could expect no clemency, emphasizing the severity and brutality of the conflict. This understanding informs the historical allusion to intense and merciless engagements among naval forces, reflecting a grim aspect of warfare where the stakes are life and death.
