Final answer:
Historical military observations suggest that unusual soldier behaviors, such as fainting from hunger or hastily drinking water, may be considered bad signs when soldiers are waiting at the front. These signs may precede an unfavorable battle situation, requiring vigilance from the observing force.
Step-by-step explanation:
Paul, the character in question, likely perceives certain behaviors and occurrences as bad signs when soldiers are waiting at the front, based on historical military observations. In historical texts, these signs can include a range of actions and conditions that might suggest weakness or impending actions by an enemy force. As an example, texts may reference that when soldiers lean on their spears, they may be exhausted from lack of food, or if they drink water hastily when sent to fetch it, they are likely suffering from thirst. Soldiers behaving unusually, whether by showing signs of weakness or acting contrary to expected military discipline, are considered bad omens that could precede an unfavorable battle situation.
Further insights can be gathered from observations of enemy troops. For instance, disorderly arrival of light chariots or the absence of a battle formation might imply that the enemy is preparing for combat. Additionally, if opposing envoys bring compliments without any substantive overtures, it could indicate a desire for a truce, which could be deceitful. The presence of such signs requires heightened vigilance and readiness for all potential scenarios.
