A "siege" is a military tactic where forces surround a fortified location, such as a city or castle, to cut off supplies and reinforcements. The goal is to weaken the defenders over time, forcing them to surrender. Sieges can last for days, months, or even years, depending on the strength of the defenses and the resources of the attacking forces. During a siege, attackers may use various methods, including bombardment with artillery or tunneling to breach walls. Historical examples of sieges include the Siege of Troy and the Siege of Vicksburg. Sieges have played a significant role in warfare throughout history, influencing the outcomes of many conflicts.
