The Mendip Hills, a landscape of rolling chalk downs straddling Somerset and Bristol, are often celebrated for their natural beauty and geological wonders. Yet, beneath this familiar facade lies a hidden layer of history, a network of sites that once played a crucial, albeit clandestine, role in national defence. This article delves into the secret history of Mendip Hills decoy sites, unearthing the stories of these camouflaged structures and their vital contribution to Britain’s survival.
During periods of intense conflict, particularly the Second World War, Britain found itself facing an unprecedented threat from the air. The Royal Air Force, though valiant, could not be everywhere at once. Enemy bombers, guided by their own navigational aids and the visible glow of urban centres, posed a significant risk to industrial targets, airfields, and military installations. The need for effective passive defence, to misdirect and confuse enemy aircraft, became paramount. This necessity gave birth to a remarkable yet largely unrecognized stratagem: the Lowestoft and Bomber Defence system, colloquially known as “decoy sites” or “starfish sites.”
Early Air Defence Strategies
The initial responses to aerial bombardment were largely reactive. Anti-aircraft guns, searchlights, and rudimentary air raid shelters were deployed. However, these measures were often insufficient against the growing capabilities of aerial warfare. The psychological impact of bombing raids on civilian morale was also a significant concern. Thus, the focus shifted towards active deception.
The Genesis of Decoy Warfare
The concept of using deception in warfare is as old as conflict itself. From Trojan Horses to feigned troop movements, military history is replete with examples of using trickery to gain an advantage. In the context of aerial bombardment, this evolved into creating artificial targets that would draw enemy attacks away from real, valuable objectives. The Mendip Hills, with its strategic location, varied terrain, and relative remoteness in certain areas, proved to be an ideal canvas for this ambitious defence initiative. The sites were not merely piles of rubble; they were meticulously planned and executed illusions.
The ‘Starfish’ Designation
The term “starfish” became the official codename for the larger, more complex decoy sites. This nomenclature was not arbitrary. It reflected the geographical distribution of these installations across the country, with each site needing to simulate a key town or city. The Mendips, as we will explore, hosted several such installations, each a carefully crafted illusion, designed to absorb the enemy’s deadly attention.
Camouflage and Concealment: The Art of the Invisible Target
The success of any decoy site hinged on its ability to convincingly mimic a real target. This was not a simple matter of construction; it involved a sophisticated understanding of enemy reconnaissance, bombing patterns, and the visual cues that guided aviators. The Mendip Hills, with its natural undulations and existing vegetation, offered a head start in this elaborate game of hide-and-seek.
Simulating Urban Glow
One of the primary functions of a decoy site was to mimic the illuminated glow of a city at night. This was achieved through the strategic placement of light sources disguised as houses, streets, and industrial areas. Various methods were employed, from simple incandescent bulbs to more elaborate arrangements designed to simulate the flickering and varying intensity of real urban lighting. The goal was to create a convincing illusion from several thousand feet in the air.
The Role of Mock Structures
Beyond lighting, actual physical structures were erected to further enhance the deception. These included mock buildings, factories, and even railway lines. Constructed from materials like corrugated iron, wood, and canvas, they were designed to appear authentic from a distance, especially in the limited visibility of night-time bombing raids. They were ghosts of industry and habitation, built to be sacrificed.
Deceptive Landscaping
The natural topography of the Mendip Hills was ingeniously incorporated into the decoy designs. Existing wooded areas could be enhanced to simulate industrial complexes, while cleared areas could be arranged to resemble open spaces or railway yards. The aim was to integrate the artificial elements seamlessly with the natural landscape, making them harder to distinguish from genuine targets.
The secret history of the Mendip Hills decoy sites reveals a fascinating aspect of World War II, where these sites were strategically used to mislead enemy bombers.

Mendip’s Deployed Illusions: Mapping the Starfish Network
The Mendip Hills became a key region for the implementation of the starfish system, hosting several significant decoy sites designed to protect vital industrial areas and RAF airfields in the West Country. These were not isolated experiments but part of a nationwide network, each a crucial node in Britain’s defensive web. Pinpointing the exact locations and understanding the operational nuances of these sites requires sifting through declassified documents and piecing together fragmented historical accounts.
The Importance of Strategic Location
The choice of the Mendips was strategic. The range of bombers operating from German-occupied territories meant that many parts of southern and western England were vulnerable. The hills offered elevated positions for observation and allowed for the creation of large, sprawling decoy areas that could effectively mimic populated centres or industrial landscapes. Their proximity to key targets, such as Bristol and its associated industries, also made them logical choices.
Designated Target Areas
Each Mendip decoy site was assigned a specific “target” to simulate. This could be a town like Bath, an industrial hub such as those found in Bristol’s expanding wartime economy, or even an important railway junction. The complexity and scale of the decoy were dictated by the importance and visual signature of the real target. These were not generic illusions; they were bespoke deceptions, tailored to fool a specific enemy.
The “Q” Sites: Decoying Aircraft Spares
Beyond the larger “starfish” sites, a more localized form of deception existed, known as “Q” sites. These were smaller, simpler decoys designed to mimic aircraft on the ground, particularly at airfields. Their purpose was to draw bombing raids away from the actual runways and hangars, protecting vital aircraft and personnel. While less elaborate than starfish sites, their role in preserving air power was equally critical. The Mendips, with their proximity to several airfields, likely hosted numerous such Q sites, though their ephemeral nature makes them even harder to trace.
Operational Procedures and Command Structures
The operation of these decoy sites was a complex undertaking, requiring constant vigilance and precise coordination. A dedicated cadre of personnel, often civilians operating under strict secrecy, managed the lighting sequences, the generation of simulated sounds, and the overall illusion. The sites were not static; their operational patterns were adjusted based on intelligence about enemy bombing routes and tactics.
The Role of the Observer Corps
The success of the decoy strategy was intimately linked to the Royal Observer Corps (ROC). These brave men and women, positioned in observation posts across the country, provided crucial real-time intelligence on enemy aircraft movements. Their reports allowed decoy operators to activate their sites at the opportune moment, maximizing their effectiveness. The Mendips, with their commanding views, were ideal locations for ROC posts, working in tandem with the hidden decoys.
The Mechanics of Illusion: Deception Technologies and Techniques
The creation of these wartime illusions was not a matter of trial and error but a calculated application of burgeoning technologies and ingenuity. The operators deployed a range of sophisticated, if anachronistic by today’s standards, techniques to create a convincing spectacle of a living, breathing, and vulnerable target. The success of these decoys was a testament to their understanding of the enemy’s perspective.
The “K” Control System
The “K” control system was a core component of the starfish decoy operations. This system allowed operators to remotely control the lighting and other effects at the decoy site. It was a rudimentary form of command and control, essential for coordinating the illusion with the perceived threat. The ability to switch lights on and off, alter their intensity, and simulate activity was crucial in maintaining the deception.
Mimicking Industrial Activity
Beyond simple lighting, operators would employ a variety of methods to simulate industrial activity. This could include the use of smoke generators to mimic factory chimneys or the emission of controlled noises designed to suggest the sounds of urban life. These sensory elements were carefully calibrated to create a believable facade.
The “B” Sites: Decoying Coastal Bombing
A further category of decoy sites, known as “B” sites, were designed to mimic coastal defence installations or shipping. While perhaps less prevalent on the Mendips themselves due to their inland location, the principles of their operation inform the broader understanding of military deception. The objective was always to present a plausible alternative target that would divert enemy ordnance from genuine strategic assets.
Fire Feints and Smoke Screens
In some instances, controlled fires and smoke screens were deliberately created to enhance the illusion of damage or ongoing activity. This was a high-risk strategy, requiring careful management to ensure the deception did not inadvertently reveal the decoy’s true nature. The aim was to create a scene of chaos and vulnerability that would attract the bomber’s attention.
The Unseen Battles: The Impact and Legacy of Mendip’s Decoys
The true impact of the Mendip Hills decoy sites is difficult to quantify precisely, veiled as it is by the inherent secrecy of their operations. However, historical accounts and declassified intelligence suggest that these camouflaged illusions played a significant, albeit often unacknowledged, role in Britain’s wartime defence. They were the silent sentinels, the unsung heroes of a nation under siege.
Absorbing Bomb Loads
The primary objective of these decoy sites was to absorb enemy bomb loads that would otherwise have fallen on populated areas, vital infrastructure, or active airfields. If a single bomber or a flight of aircraft was successfully diverted by a decoy, the lives saved and the resources preserved were immeasurable. Each bomb that detonated on an empty field or a mock structure was a victory for the unseen defenders.
The Psychological Warfare Element
Beyond the physical impact, the decoy sites also served a psychological purpose. The constant threat of bombing, even if illusory, could take a toll on enemy morale and operational efficiency. The knowledge that their efforts might be in vain, that they were being tricked, could have a demoralizing effect on bomber crews.
Protecting RAF Airfields
The protection of Royal Air Force (RAF) airfields was a particularly critical application of decoy tactics. The destruction of an airfield could cripple a region’s defence capabilities, hindering offensive operations and leaving the civilian population vulnerable. The starfish and Q sites surrounding these airfields acted as a crucial buffer, a shield forged from deception.
The Cost of Deception: Civilian Casualties
It is important to acknowledge that, despite their defensive purpose, decoy sites were not entirely without risk. In some instances, enemy aircraft, either through superior reconnaissance or sheer chance, did identify decoys as what they truly were: manufactured targets. In such cases, the civilian personnel operating the decoy, or even nearby civilians if the site was not sufficiently isolated, could become casualties. This highlights the inherent dangers and sacrifices associated with such clandestine operations.
