Final answer:
When drawing near to a city for battle, it is important to consider the presence of fortified cities, assess the likelihood of victory, and strategically position oneself.
Step-by-step explanation:
When you draw near to a city to fight against it, there are several strategies and considerations to keep in mind. One important aspect is the presence of fortified cities in the enemy's rear. This means that the army must be cautious and aware of potential attacks from the rear.
Additionally, it is crucial to assess the likelihood of victory. If the odds are in favor of victory, then engaging in the battle is recommended. However, if victory is unlikely, it is best to avoid the fight, even if ordered to do so by the ruler.
Lastly, the terrain and positioning can greatly impact the outcome of the battle. It is advantageous to hold high ground, sunny spots, or places where the enemy must hasten to defend. Additionally, provoking the enemy into approaching difficult or dangerous positions can provide an advantage.
