In "Master and Commander" by Patrick O'Brian, Jack comments on the nature of fighting against Spaniards. He acknowledges their courage, asserting that they are not cowardly. However, he notes a critical advantage in combat: the Spaniards are often unprepared for the challenges they face. This lack of readiness can be a significant factor in warfare, implying that even brave opponents can be vulnerable if they are caught off guard. Jack's observation reflects a strategic understanding of conflict, emphasizing that preparation plays a crucial role in determining the outcome of battles. His smile, despite the seriousness of the subject, reveals his confidence in being able to exploit this weakness, suggesting that the unpredictability of warfare allows for opportunities even against formidable foes.
