Not only that, an important thing to consider as the besieging force was to have at least triple the numbers of the garrison defending the castle.[1] So if a castle was garrisoned by a defending force of 2,000, you wanted at least 6,000 men as the besieging force to even stand a chance of winning the siege whether through killing or attrition. And this quickly grows exponentially for the besiegers as the defending force becomes bigger: If the defenders numbered 5,000 men, you wanted 15,000 men as the besiegers. So not only did the besiegers have a harder time fighting compared to the defenders, the logistical requirements and demands for the besiegers was significantly larger than anything the defenders had to deal with.
