ABSTRACT In 1940, with the fall of France imminent, Britain prepared secret ‘Auxiliary Units’ tasked with guerrilla activities [Scallywagging] in the invading army’s rear. Patrols of four to eight highly skilled men used below-ground Operational Bases (OBs) in remote locations to avoid detection. No official records are released, but OBs were ‘Mark I’, enlarged deer setts, smuggler caves, etc., and Mark II, prefabricated designs by the Royal Engineers. This paper details three sites in Suffolk: one unknown Mark I was destroyed, a Mark II was partially intact and a Mark II was fully intact, all in secluded woods. Geophysical surveys found metal detectors optimal for location, with mid-frequency GPR/ERT optimal for characterisation. Archaeological finds included home-made braziers, 1940 kerosene heater stove, metal pans, ventilation systems and escape tunnels. This study shows OBs varied in construction and condition, with surveys detecting and characterising them, bringing WWII British ‘invasion’ history into the wider scientific community and public domain.

Scallywag 掩体：英国二战辅助部队作战基地 (OB) 的地球物理调查

摘要 1940 年，随着法国的沦陷迫在眉睫，英国准备了秘密的“辅助部队”，其任务是在入侵军队的后方进行游击活动 [Scallywagging]。由四到八名高技能人员组成的巡逻队在偏远地区使用地下作战基地 (OB) 以避免被发现。没有发布官方记录，但 OB 是“Mark I”，放大的鹿群，走私者洞穴等，以及 Mark II，由皇家工程师预制设计。这篇论文详细介绍了萨福克郡的三个遗址：一个未知的 Mark I 被摧毁，一个 Mark II 部分完好无损，一个 Mark II 完好无损，都在僻静的树林中。地球物理调查发现金属探测器最适合定位，中频 GPR/ERT 最适合表征。考古发现包括自制的火盆、1940 年的煤油暖炉、金属锅、通风系统和逃生隧道。这项研究表明，OB 的结构和状况各不相同，调查发现并表征了它们，将二战英国“入侵”历史带入了更广泛的科学界和公共领域。
