HMS Tilbury

The final voyage

HMS Tilbury, a 58-gun fourth-rate launched in 1745, formed part of Vice-Admiral Francis Holburne's squadron blockading the French fortress of Louisbourg during the Seven Years' War. On 24–25 September 1757 an exceptionally violent hurricane struck the fleet off Cape Breton; modern meteorological reconstruction from ship's logs places its intensity in the range of a Category 4 storm, unmatched by any recorded Atlantic hurricane to strike the region since [1](https://cp.copernicus.org/articles/20/1141/2024/cp-20-1141-2024.html). Tilbury was driven onto the rocks.

Captain Henry Barnsley and roughly 120 of his crew drowned; the remaining survivors were taken prisoner by the French, who are recorded as having treated them well [2](https://en.wikipedia.org/wiki/HMS_Tilbury_(1745)). The wreck site, known locally as the Tilbury Rocks near St Esprit, Cape Breton, remains a documented artifact and archive source for the 1757 storm.

What was aboard

No pay-chest or specie manifest for this ship's final voyage has been located in the sources consulted for this report; claims of a documented treasure cargo are not supported by the primary accounts of her loss.

Ship's ordnance: 58 guns of a fourth-rate ship of the line, as recorded in her Admiralty specifications.

Naval stores and rigging: The ordinary material complement of an active Royal Navy warship on blockade duty.

How to collect

Do not expect specie: No coin or pay-chest cargo is documented for this loss; treat 'Tilbury treasure' claims as unsupported.

Verify against Nova Scotia Archives records: The site and its known finds, such as recovered cannon, are documented; ask how a specific object matches that record.

Understand the site as a war grave: With the captain and roughly 120 crew killed, the wreck is a site of significant loss of life and should be treated accordingly.

Confirm Canadian heritage compliance: Any recovery from Nova Scotia or Cape Breton waters should meet applicable Canadian underwater heritage requirements.
