考古学家史都华普莱尔与前英国皇家海军陆战队员蒙提霍尔斯，一起探索围城器械的破坏力。自有战争以来，就有围城之役，例如亚历山大大帝的泰尔城之围， 1191年的阿克雷之围，以及发生於1992年的塞拉耶佛之围。史都华和蒙提研究投石机和抛石机，了解这两种作战器械的功能与准确度。
Our two hosts, archaeologist Stuart Prior and ex-Royal Marine Monty Halls, explore the destructive power of Siege Engines in history. Sieges are as old as warfare itself, like Alexander the Great’s siege of Tyre, the Siege of Acre in 1191, right up to the modern day, with the Siege of Sarajevo in 1992 being the longest in modern history. Monty and Stuart follow the building of a mangonel, and trebuchet, in order to test their power and accuracy.
