Abstract The largest escape of German Prisoner of War (PoW) in WW2 was in March 1945 from Camp 198, situated in Bridgend, South Wales, UK. Since camp closure the site has become derelict, and has not been scientifically investigated. This paper reports on the search to locate the PoW escape tunnel that was dug from Hut 9. This hut remains in remarkable condition, with numerous PoW graffiti still present. Also preserved is a prisoner-constructed false wall in a shower room behind which excavated material was hidden, though the tunnel entrance itself has been concreted over. Near-surface geophysics and ground-based LiDAR were used to locate the tunnel. Mid-frequency GPR surveys were judged optimal, with magnetometry least useful due to the above-ground metal objects. Archaeological excavations discovered the intact tunnel and bed-board shoring. With Allied PoW escape camp attempts well documented, this investigation provides valuable insight into German escape efforts.

在南威尔士布里真德 PoW Camp 198 进行的多学科调查：1945 年 3 月大规模逃亡的地点

摘要 二战期间德国战俘 (PoW) 最大的一次越狱发生在 1945 年 3 月，发生在英国南威尔士布里真德的 198 营地。自营地关闭以来，该地点已被遗弃，并且没有经过科学调查。本文报道了寻找从 Hut 9 挖出的 PoW 逃生隧道的位置。这个小屋仍然完好无损，许多 PoW 涂鸦仍然存在。还保留了一个淋浴房中的囚犯建造的假墙，在其后面隐藏了挖掘出的材料，尽管隧道入口本身已被混凝土覆盖。近地表地球物理学和地面激光雷达用于定位隧道。中频 GPR 测量被认为是最佳的，由于地上金属物体，磁力测量最不实用。考古发掘发现了完整的隧道和床板支撑。
