ROYAL NAVY CAUGHT THE LOCH NESS MONSTER DURING WW2: Newly Found Letters Prove It
Three letters discovered in a grandfather’s papers reveal a classified wartime incident when British naval vessels caught something extraordinary in their anti-submarine nets.
In the summer of 1941, while battles raged across Europe and the Atlantic, two Royal Navy vessels conducted defense operations at Loch Ness. The incident that followed stayed buried in military records and personal memories for decades, until John Gibbens found letters among his late grandfather’s papers.
The Wartime Navy at Loch Ness
During World War II, HMS Ocean Swell and HMS Norbreeze laid anti-submarine nets across harbors and strategic waterways. These underwater barriers consisted of heavy wire and interlocking steel rings, designed to entangle submarines attempting to penetrate British waters.
The nets functioned primarily as deterrents since their actual effectiveness was largely unknown to enemy forces. Loch Ness’s strategic position in the Scottish Highlands, combined with its depth and connection to the sea through the River Ness and Caledonian Canal, made it a potential vulnerability requiring protection.
Setting and maintaining the nets required precise coordination. The nets needed support from surface ships equipped with depth charges to be effective. Operations continued around the clock, with sailors working in shifts to secure Britain’s waters from underwater threats.
The Incident of May or June 1941
According to the letters, in May or June 1941, HMS Ocean Swell and HMS Norbreeze had an extraordinary experience when some sort of unknown sea serpent became entangled in the anti-submarine nets and was partially hoisted out of the water before the gear gave way.
The encounter occurred during routine net operations. The crew of HMS Ocean Swell, including Lewis Tyler, confronted something outside their training or expectations. The mechanical winches and steel cables designed to halt submarines strained under the weight of their catch.
The creature was partially hoisted out of the water before the gear gave way. The crew got at least a partial view of their catch. Equipment designed to handle military submarines failed under the strain, indicating either exceptional size or desperate strength.
Lewis Tyler: The Witness Who Kept Mum
Lewis Tyler served aboard HMS Ocean Swell during the incident. Before this encounter, Tyler had served aboard the Royal Yacht, where he showed the future Queen Elizabeth II and her sister Princess Margaret, then children, around the engine room. Tyler was a trusted serviceman with access to sensitive positions within the Royal Navy.
Tyler died in 1975, his account unpublished. For over thirty years after the incident, he kept silent about his experience. Military secrecy, personal discretion, or fear of ridicule may have bound his silence.
His silence extended even to his own family. His grandson John Gibbens stated he had no idea his grandfather had seen a serpent during his lifetime, only discovering the truth after finding letters among Tyler’s papers following his death. John told reporters that had he known about the incident when his grandfather was alive, he would have pestered him about it relentlessly, describing Tyler as a lovely man whom everyone loved.
The Loch Ness Investigation Bureau’s Interest
Twenty-six years after the wartime incident, David James knew about the naval encounter. The Loch Ness Phenomena Investigation Bureau was formed in 1962 by politician David James, naturalist Sir Peter Scott, and Constance Whyte to study Loch Ness and identify the creature or determine the causes of reports.
David James, Member of Parliament and bureau founder, had learned about the 1941 naval incident. The organization operated with annual subscriptions covering administration costs. Volunteers watched the loch from vantage points with film cameras equipped with telescopic lenses. By 1969, the bureau had 1,030 members, including 588 from the UK.
In May 1967, David James wrote three letters to Lewis Tyler. The first letter specified the incident details: the vessels’ names, the approximate date, and the sequence of events. James had access to some official record or witness testimony. His request for details about size, shape, color, and texture showed a scientific approach to evidence gathering.
A second letter thanked Tyler for completing a questionnaire; a third stated his account would prove useful to James’s research. Tyler’s response and questionnaire completion shows he was willing to share his experience with investigators privately.
The Lost Account
Tyler’s grandson John doesn’t have the account his grandfather provided to investigators. John believes the account was never published, noting his mother would have told him otherwise.
Tyler’s account died with him and possibly with David James, who passed away in 1986. The bureau disbanded in 1972 after ten years without solving the Loch Ness mystery. If Tyler’s account exists in the bureau’s archives, it hasn’t surfaced publicly.
John Gibbens noted discovering what his grandfather said would be valuable, now fifty years after Tyler’s death. The original letters provide the only tangible evidence the incident occurred and was investigated decades later.
The Wider Context of Wartime Secrets
HMS Ocean Swell’s encounter fits patterns of wartime incidents that stayed classified or unspoken for decades. During World War II, military personnel witnessed events they were ordered never to discuss. Naval operations secrecy was particularly strict, as vessel locations and activities could provide enemy intelligence.
Anti-submarine nets were deployed extensively during both World Wars, including the Dover Barrage spanning the English Channel and defenses at Scapa Flow. Naval personnel operating these defenses could identify conventional threats and distinguish between enemy craft, marine life, and debris.
Experienced sailors described their catch as a “sea serpent” rather than identifying it as a known animal or object. These men operated in maritime environments and knew ocean inhabitants and objects that could entangle in equipment.
The Physical Evidence That Never Was
The mechanical failure prevented the crew from fully hauling in their catch. After the creature was partially hoisted, the gear gave way. This military-specification equipment could handle submarines attempting to break through.
The failure of such equipment indicates extraordinary weight, exceptional thrashing force, or both. Without complete retrieval, no physical evidence verified the crew’s observations.
During active wartime operations, pursuing the matter further would have been low priority. With German U-boats threatening British shipping, investigating an unusual marine encounter wouldn’t warrant diverting ships and personnel from defense duties.
The Investigation Bureau’s Methods
The Loch Ness Phenomena Investigation Bureau was one of the most organized attempts to solve the Loch Ness mystery. In 1961, expert referees including professors of zoology from Oxford and Cambridge met at London’s Linnaean Society and concluded there was a prima facie case for investigation.
David James’s approach to Tyler’s case shows the bureau’s methodology. Rather than sensationalizing, James sought specific, measurable details for scientific understanding. His data collection mirrored marine biologists’ methods when cataloging new species.
The bureau maintained camera stations with 35mm movie cameras and telephoto lenses. Mobile units positioned in laybys achieved approximately 80% coverage of the loch’s surface. This systematic observation advanced beyond earlier documentation attempts.
Why This Story Matters Now
These letters’ discovery decades after Tyler and James died raises questions about similar accounts in attics, archives, and forgotten filing cabinets. John Gibbens found them among his grandfather’s papers, having no knowledge of the encounter during Tyler’s lifetime.
The naval connection adds credibility. These weren’t tourists or locals with economic interests. Military personnel engaged in wartime operations encountered something unexpected and reported it through channels.
David James’s specific knowledge in his initial letter – the ships, date, and events – implies documented information from military records or other crew testimony. This wasn’t rumor but a documented incident warranting investigation twenty-six years later.
The Mystery Remains
What did HMS Ocean Swell catch in its anti-submarine nets that wartime summer? Without the complete specimen, we lack definitive answers. Tyler’s lost account compounds the mystery, leaving only the outline of events.
According to Ronald Binns, a former member of the Loch Ness Phenomena Investigation Bureau, there is probably no single explanation for the monster sightings at Loch Ness. Binns contends that human psychology plays a role, with the eye’s ability to see what it wants and expects to see contributing to misidentifications of known animals, inanimate objects, or effects.
The HMS Ocean Swell incident differs from typical sighting reports. This wasn’t a distant observation but physical interaction with something substantial enough to damage military equipment. The crew caught it, however briefly.
Loch Ness’s mysteries extend beyond tourist photographs and disputed footage. Sometimes evidence comes from military personnel doing their duty who encounter something extraordinary and keep silent for life.
Lewis Tyler took his complete account to his grave. David James’s investigation files, if they exist, remain unlocated. Other crew members from HMS Ocean Swell and HMS Norbreeze left no known records. Three letters remain, along with a grandson’s determination to understand his grandfather’s secret, and questions about what lies hidden in Loch Ness’s deep waters, or in forgotten archives of those who once protected those waters from enemy threats.
