How many soldiers are needed to attack a castle?

The number of soldiers needed to attack a castle depends on various factors, including the castle's size, defenses, and the attackers' strategies and resources. Historically, a successful siege could require hundreds to thousands of soldiers, as attackers needed to breach walls, maintain supply lines, and withstand counterattacks. Additionally, the use of siege equipment and tactics, such as creating diversions or employing specialized troops, plays a crucial role in determining the necessary force size. Ultimately, careful planning and assessment of the specific situation are essential for a successful assault.
