In browsing the National Archives, I came across an interesting reference to a work request concerning Fort Halstead. A request in May 1945 for six small building schemes had been submitted for the expansion and development of the site at Fort Halstead, but interestingly was a seventh item – “Bomb damage repairs to East Casemates.” I wasn’t previously aware of any enemy bomb damage inflicted on the Fort during the war, mainly in part due to its discreet location outside the London suburbs.
The case for the repairs was put down to it being “necessary to store liquid feeds i.e. methyl nitrate, nitro methane, DEGDN and NG mixtures, for experimental work of the highest priority.” The old casemates apparently satisfied the cool and dry conditions required for the sensitive storage, provided the necessary repairs were carried out. This got me looking for evidence of this bomb damage.
