Which risk increases when a besieged fortress's curtain walls undergo progressive deformation?

💡 Explanation

A compromised wall allows 'impact force concentration', because a deformable wall transfers incoming force non-uniformly. Therefore, rammings achieve greater effect, rather than distributing force widely as against a rigid wall.
