Which tactic enabled Roman siege engines overcome early defensive walls constructed solely from loosely stacked stones,?

💡 Explanation

When impacting an unconsolidated stone wall, rapid concentrated impacts by siege engines like trebuchets generate dynamic force exceeding the stone bond strength, initiating dislodgement and collapse. Therefore, focused impacts, rather than incendiaries, tunnelling, or feints, is correct given this specific constraint of weakly-bonded stone structures.
