Issued by the War Office in 1944 under the stark banner “Neptune BIGOT Top Secret,” this remarkable sheet from the Bogus Map series distills the British plan for Sword Beach into an instrument of absolute clarity and control. A disciplined grid overlays the littoral, while the sea is washed in blue tones that cue approach routes and nearshore hazards. Red ink commands attention at the title and key operational areas, where the landing lanes Peter, Queen, and Roger are crisply distinguished. The cartography is purpose-built for action after touchdown: a staff officer’s view of the beachhead, translating terrain into tasks, timings, and flows during the opening movements of Operation Neptune.

Secrecy and deception are woven into the very language of the map. In place of authentic Norman placenames, global aliases—Cairo, Vienna, Hamburg, Tunis, Lisbon, Madrid, Dresden, even Ganges—cloak the true geography, a deliberate misnaming that protected sources, plans, and lives. The “BIGOT” marking denotes the highest echelon of Overlord clearance, restricting this intelligence to a narrow circle. The legend becomes a cipher key, correlating numbers and colors to functions without betraying targets to prying eyes. It is cartography as counterintelligence, where every label is both information and misdirection.

Beyond its veil of code words, the sheet is a masterclass in logistics at scale. Symbols and numeric references designate ammunition dumps, bivouac sites, collecting points, civilian refugee camps, and even burial areas—evidence of sober, comprehensive planning to sustain combat power, manage casualties, and stabilize the shoreline once seized. The color-coded operational bands and rectilinear grid turned the chaos of surf, sand, and lanes into navigable choreography. In this sense, the map does not simply show a battlefield; it scripts the backstage of victory, where fuel, food, arms, and aid arrive in sequence and at speed.

The geography beneath the codenames is Normandy’s Sword sector, its coastal contours and landforms rendered with tactically relevant nuance. Varying depths, tidelines, and gradients foreshadow the breakers, bars, and exits that would govern vehicles and men pushing inland. Though the sheet masks them, the area frames the approaches near Luc-sur-Mer, Lion-sur-Mer, La Brèche d’Hermanville, and Ouistreham—localities central to British objectives on D-Day. The alignment of Peter, Queen, and Roger corridors with practicable beach exits is unmistakable, revealing how intelligence and engineering fused to transform a hostile shoreline into a functioning port of war on the very day it was taken.

As a historical artifact, this map captures a singular fusion of precision, prudence, and deception at the heart of Operation Overlord. It records not only where the British intended to land, but how they meant to hold, supply, and expand the beachhead under fire—an orchestration that made the world’s largest amphibious assault sustainable. The arresting red title, austere symbology, and carefully coded toponyms make it both visually striking and intellectually gripping. It is a rare window into the clandestine craft of wartime mapping, where the art of naming—and of not naming—was as consequential as the lines, depths, and roads themselves.

This map looks great at every size, but I always recommend going for a larger size if you have space. That way you can easily make out all of the details.

This map looks amazing at sizes all the way up to 90in (230cm). If you are looking for a larger map, please get in touch.

The model in the listing images is holding the 24x36in (60x90cm) version of this map.

The fifth listing image shows an example of my map personalisation service.

This would make a wonderful birthday, Christmas, Father's Day, work leaving, anniversary or housewarming gift for someone from the areas covered by this map.

This map is available as a giclée print on acid free archival matte paper, or you can buy it framed. The frame is a nice, simple black frame that suits most aesthetics. Please get in touch if you'd like a different frame colour or material. My frames are glazed with super-clear museum-grade acrylic (perspex/acrylite), which is significantly less reflective than glass, safer, and will always arrive in perfect condition.

This map is also available as a float framed canvas, sometimes known as a shadow gap framed canvas or canvas floater. The map is printed on artist's cotton canvas and then stretched over a handmade box frame. We then "float" the canvas inside a wooden frame, which is available in a range of colours (black, dark brown, oak, antique gold and white). This is a wonderful way to present a map without glazing in front. See some examples of float framed canvas maps and explore the differences between my different finishes.

For something truly unique, this map is also available in "Unique 3D", our trademarked process that dramatically transforms the map so that it has a wonderful sense of depth. We combine the original map with detailed topography and elevation data, so that mountains and the terrain really "pop". For more info and examples of 3D maps, check my Unique 3D page.
