The Survey gave advice on where to get sand for sandbags. They also gave advice on water supplies for new airfields and army camps (also suggested suitable sites for airfields), on resources such as coal, Iron Ore, Oil-Shale, underground storage areas for personnel and storage, building materials for military instillations and produced a series of wartime pamphlets. Some of the geologists probably did some work for MI 10 on the mineral resources of Germany and the occupied countries. Edward Bailey's history of the Survey mentions that he had been temporarily buried by an explosion caused by a V1 flying bomb!
Preparing for war
As the prospect of war grew more likely, arrangements were made for what would happen to the Geological Survey of Great Britain and its staff.
Like many others, members of the Geological Survey joined the Home Guard to defend Britain from possible invasion.
Secret and confidential
Geologists from the Survey were involved in a variety of confidential and secret working during the war.
At 11:47pm on 10 September 1940 a German bomb damaged the Geological Museum at Exhibition Road, London. Edward Bailey in his book Geological Survey of Great Britain records that the bomb "broke half the windows" and a later near miss in 1941 "completed out deglazing."
The other side
The British were not alone in their use of geologists during the Second World War as these documents show.
Even as the war continued, plans were drawn up for what work the Survey would be doing once peace finally came.
