Frigate · 1778–1797 · Cork, Ireland

La Surveillante

Also known as Surveillante.

La Surveillante, a French frigate built in 1778 and scuttled in 1797, lies at 8–12 metres off Cork, Ireland.

Beneath the sheltered waters of Bantry Bay lies one of the most archaeologically significant wrecks in Ireland -- a French frigate scuttled during the failed 1796-97 expedition to support Irish rebellion against British rule. La Surveillante went down on 2 January 1797 after her crew chose scuttling over capture by the Royal Navy.

Lost for nearly two centuries, the wreck was identified in 1981 during marine surveys following the Whiddy Island oil terminal disaster, and confirmed in 1997 when the ship's bell was located. Preservation is exceptional: the wreck survives from the orlop deck down to the copper-sheathed keelson, with the entire site contained within just 50 by 25 metres.

A nationally protected monument (NMS Wreck Number W08507), diving requires prior permission from authorities.

History and LossLost January 2nd, 1797 · Scuttled · French Revolutionary Wars / 1798 Rebellion · Cork, Ireland.

In December 1796, a French fleet of 43 ships carrying approximately 15,000 troops sailed from Brest to support an Irish rebellion against British rule. Severe storms scattered the fleet and prevented a landing. La Surveillante, damaged and unable to return to France, was scuttled by her crew in Bantry Bay on 2 January 1797 to prevent capture by the Royal Navy.

The failed expedition is known as the Bantry Bay Expedition or Hoche's Expedition.

Built 1778; 19 years in service, also recorded as Surveillante. Lost January 2nd, 1797, scuttled during French Revolutionary Wars / 1798 Rebellion.

Condition of the WreckBroken, in 8–12 m, on fine-grained sediment.

Intactness

Exceptionally well preserved for Irish waters. Survives from the orlop deck down to the copper-sheathed keelson. The low-energy, fine-grained seabed environment has protected the timbers. Archaeological surveys by the National Monuments Service in 1999-2000 documented the site extensively.

One of the most archaeologically significant wrecks in Ireland.
