By 1940, attacks on military airfields were more than just a threat, they were a fact. The German
invasion of Crete that year had alerted the Royal Air Force to the inadequacy of existing airfield defences and
accordingly there began an extensive programme of fortification-building in the form of pillboxes, gun emplacements,
trenches and barbed wire. In the event of an attack, defence was to be co-ordinated from a purpose-built underground
bunker - the battle headquarters. Initially these were only built at fighter stations, but after 1942 battle
headquarters were seen at all RAF command stations [1], including, in c. 1943, Dunsfold. [2]
![]() | Dunsfold Aerodrome itself was begun on the 11th May 1942
by the the 2nd Battalion Royal Canadian Engineers and completed in just twenty weeks, after which it was operated by
the Royal Canadian Air Force under the name of RCAF Dunsfold and was initially a fighter station, home to the
Mustang Mk 1s of the 400 and 414 Squadron RCAF. This remained the case until the following year with the arrival of
the Mitchell Mk11 medium bombers of the 98 and 180 Squadrons RAF and later 320 squadron of the Royal Netherlands
Naval Air Service [2a]. It was presumably shortly after the Royal Air Force arrived that the Battle Headquarters were built at Dunsfold, to the design specified by Air Ministry drawing 11008/41. These consisted of a brick and concrete bunker entered by a ladder on one side into a lobby. Standing in the lobby, to the left would be a door to the office, which in turn led on to the sleeping quarters, while straight ahead would have been the latrine. To the left of this was a door to the largest chamber - the mess room. At the end of this room, through a door on the right was a small lobby which led to a semi-subterranean observation post to be manned by the Local Defence officer and to an emergency exit. [3] The whole structure was in fact only partly beneath ground level, the rest being covered by a raised mound of earth. The structure seems to have been maintained throughout the war, but had fallen out of use by the time it was stripped when the base was decommissioned in 1946 [4]. |
