Reasons for Designation

Although of comparatively recent date, 20th century military sites are increasingly seen as historic survivals representing a defining episode in the history of warfare and of the century in general; as such they merit careful record and, in some cases, preservation. One of the more significant developments in the evolution of warfare during this period was the emergence of strategic bombing in World War II, and this significance was reflected by the resources invested in defence, both in terms of personnel and the sites on which they served. During the war, the number of people in Anti-aircraft Command reached a peak of 274,900 men, additional to the women soldiers of the ATS who served on gunsites from summer 1941, and the Home Guard who manned many sites later in the war. A national survey of England's Anti-aircraft provision, based on archive sources, has produced a detailed record of how many sites there were, where they were and what they looked like. It is also now known from a survey of aerial photographs how many of these survive. Anti-aircraft gunsites divide into three main types: those for heavy guns (HAA), light guns (LAA) and batteries for firing primitive unguided rockets (so called ZAA sites). In addition to gunsites, decoy targets were employed to deceive enemy bombers, while fighter command played a complementary and significant role. The LAA sites used a range of weapons in defence against lower flying aircraft, and have a particularly wide distribution around the south and east coasts and close to cities and industrial and military targets such as airfields. Of all the gunsites, these were the least substantial, with the fabric depending to a large extent on the type of weapon employed. The Bofors machine gun was the weapon most frequently provided with a static emplacement. It was also the only LAA weapon whose associated structures were covered by formal design drawings, the remainder taking the form of simple fieldwork dugouts, at most making use of concrete blocks for revetments. The Bofors gun had three varieties of emplacement: ground level fieldworks, which were the most common; roof mountings; and towers of steel or concrete. These towers were never very numerous, with only 81 concrete examples supplied for use. These static Bofors sites were sometimes provided with on-site magazines, the design being left to local initiative. Remote positions for all types of gun were often provided with a few ancillary structures or domestic buildings, sufficient only to cater for their crew of 12 men, while ground defences were modest. The on-site magazines were often Anderson shelters adapted for the purpose. With few exceptions, sites were therefore small, slight and highly diverse. Nearly 1,250 LAA gunsites are recorded as having been built during World War II and can be accurately located. Around 50 of these have some remains surviving, though at only around 40 sites are these thought sufficient to provide an understanding of their original form and function. Surviving examples are therefore sufficiently rare to suggest that all 40 examples are of national importance.

The World War II Bofors Anti-aircraft gun platform 340m south east of Cheshunt railway station is one of only a few survivals of its type in the country. As such, it is an important historical structure, serving as a physical record of similar emplacements which have been demolished elsewhere. It provides a significant, visible reminder of the nature of home defence during World War II and gives an insight into the development of anti-aircraft measures in the region around Waltham Abbey.

Details

The monument includes a World War II Bofors Anti-aircraft gun platform overlooking the Lee Valley Navigation canal to the west, and the lakes of the Lee Valley Country Park to the east.

The platform is of concrete construction and conforms to the Directorate of Fortifications and Works design DFW 55087, which is an early type, the first examples of which were produced during the spring or early summer of 1940. The tower was designed to raise a 40mm Bofors gun and its operational equipment above surrounding obstacles in order to achieve an all-round field of fire. The emplacement includes two parallel, independent towers approximately 6m tall, separated for much of their height by a 1.5m gap and fanning out at roof level to form two large flat platforms set 0.3m apart. The gap was needed to insulate the sensitive predictor equipment (sited on one platform) from the vibrations of the Bofors gun (sited on the other). The northern platform is rectangular in shape, measuring 3.82m by 6.43m, and has a number of holes forming a rectangular pattern in the roof. Contemporary photographs show that these would have served to secure, with bolts, a steel tank to the roof to afford protection to the emplacement commander and crew operating the predictor equipment. The southern platform is approximately 6 sq m and housed the Bofors gun itself; the gun mounting ring is still in place in the centre of the platform with eight fixing bolts in position. At each corner of the roof are recesses for the storage of up to 400 rounds of ammunition. Two rectangular openings (originally with steel shutters of which the frames and hinges remain) facilitated the supply of ammunition from the upper room of the northern tower (which housed most of the ammunition in a series of shelves and lockers) to the gunners. Each tower has two rooms; an external concrete staircase provides access from the ground floor to the first floor ammunition store in the northern tower and then up to the roof. At ground level the northernmost tower has a pillbox-type room with a single loophole and low ceiling.

The southern tower has two high-ceilinged rooms at ground level; one has a large number of vents and rectangular openings and most probably housed the generator; the other room functioned as a general operations room. Both rooms have loopholes for defence with light weapons.

Photographs in a contemporary magazine article published in November 1943 show the gun operated by its crew of four, plus an officer manning the telephone, a spotter scanning the sky with binoculars and two further crew members in position protected within the steel tank. In one photograph supplies are being ferried across the River Lee navigation canal to the emplacement.
