During a Roman siege, which outcome results when supporting timber foundations under a wall are ignited?

💡 Explanation

Igniting timbers causes localized subsidence because charring reduces their load-bearing capacity via section modulus reduction from the fire, resulting in uneven foundation settlement. Therefore, the undermined wall is weaker than before, rather than catapult ranges improving.
