Overview
- Grandson John Gibbens says he discovered three May 1967 letters to his late grandfather, sailor Lewis Tyler, referencing a Loch Ness incident.
- The letters, written by Loch Ness Phenomena Investigation Bureau figure David James, seek details of a May–June 1941 episode involving HMS Ocean Swell and HMS Norbreeze.
- One letter recounts claims that an unknown 'sea serpent' became entangled in anti-submarine nets and was partially hoisted before the gear failed.
- Follow-up notes thank Tyler for completing a questionnaire and say his account would be useful, but the detailed statement has not been found or published.
- No independent Royal Navy logs or archival records corroborate the incident, though recent anecdotal sightings continue to renew interest in the legend.
