Very little information is available about the Walter B. Allcock Society, a society that allegedly operated with deliberate secrecy from the 1800s to the mid-20th century. It had strong ties to elite institutions including both Oxford and Cambridge, and its disparate membership included prominent scientists, business owners, and leaders of public policy. According to a short biography published in a philosophical article in the 1880s, they aimed to use their connections, education, resources and background to meaningfully improve the quality of life of the British population through unpublicised means.

Activity Period (1880s - 1950s)

References to the society died out in the mid 20th century. However, a commenter on an earlier version of this post mentioned that he believed he once saw a sign for a meeting in the early 2000s in Cambridge, which suggests that the group may still be active.

Alleged Projects

• Project Mirrorbridge
  According to obscure naval-technology notes, the Society explored early “mirror-networking” — a concept where isolated research groups maintained synchronised copies of sensitive technical documents, stored in multiple secret locations, including maritime ones. The aim was resilience: national knowledge could not be lost to sabotage, disaster, or bureaucratic error.


• Theory of Desynchronisation
  Cited briefly in an undated typescript appended to an engineering pamphlet (Notes on Rotational Assemblies, believed pre-1930), it described how two concentric rotating panels under pressure might drift into an “inverse synchrony” rather than stabilise. The idea was dismissed by contemporaries but resurfaced in a 1954 bibliographic note.

La Vigie d’Argent (1934)

The society is included here as it was connected to the vessel La Vigie d’Argent (1934) through papers found aboard on recovery. La Vigie d’Argent was a 70-ft aluminium-hulled fast coastal freighter found in 1951, half-submerged in the tidal refuge of Anse de Pors Liogan, Brittany. Local boats use this inlet as a natural shelter: accessible at high tide, but nearly landlocked at low tide. La Vigie d’Argent was discovered listing heavily to port, engine room partly flooded, with no crew and no signs of forced entry. Authorities assumed mechanical failure followed by deliberate beaching to prevent total loss, but no one ever claimed salvage rights.

The circumstances of its rediscovery in 1951 are difficult to reconcile with any routine loss. The tidal refuge at Anse de Pors Liogan was a narrow, difficult-to-approach pocket known almost exclusively to local fishermen. Entering it required precise timing and intimate knowledge of submerged rock shelves. For La Vigie d’Argent — a fast cargo vessel built for open coastal water — to appear there, half sunk yet positioned as though intentionally run aground, is highly irregular. No distress reports were logged, no cargo remained, and no post-war registry lists her as active in the region.

Boats like La Vigie d’Argent were used by the military and secret services for transporting people, tools and weaponry to aid resistance efforts in France at the time. Due to the timing of the find, the lack of distress reports and lack of cargo, it is possible that the vessel formed part of an undisclosed project involved in the war effort.
