- The Chicago Underground WarThe Chicago Underground War was the theory that Chicago’s hidden freight-tunnel railway, including the small underground electric trains that later folklore sometimes called “Bunnies,” formed a covert logistics network for gangland operations during Prohibition. In the specific St. Valentine’s Day Massacre version, the theory claimed that bodies, weapons, or participants were moved through these tunnels to conceal routes of travel or dispose of evidence after the killings. The historical tunnel system was real: a freight and utility tunnel network built under downtown Chicago, with an early but short-lived mail contract and long-running freight service. The conspiracy version arose by combining that genuine underground infrastructure with the city’s gang mythology and then stretching the tunnel system beyond what is clearly documented in the massacre itself.
- The "Bank of England" TunnelThis theory claimed that a hidden tunnel connected the Bank of England to the monarch's private rooms, often phrased as a passage to the Queen's bedroom, so that gold or emergency funds could be moved without public scrutiny. The story drew on older urban tunnel folklore and on the Bank's real subterranean security concerns. Its strongest historical anchor is the well-known 1836 incident in which a sewer worker demonstrated that an old drain led beneath the Bank's gold vault, proving that the institution's underground vulnerability was not entirely imaginary.
