Which defensive outcome resulted when a Roman fort wall’s timber bracing decayed over time in Northern Europe?

💡 Explanation

When timber decayed, hoop stress integrity was compromised because the tied arches lost support, leading to the outer stonework collapsing outwards. Therefore, stonework collapse resulted, rather than acoustic damping, defense increase, or drainage improvement, each require different construction or degradation mechanisms.
