HMS Colossus

A 74-gun Royal Navy third-rate, veteran of the French Revolutionary Wars, wrecked off Samson in the Isles of Scilly while carrying wounded sailors and part of Sir William Hamilton’s collection of classical antiquities.

History

HMS Colossus was a 74-gun Courageux-class third-rate ship of the line, launched at Gravesend in 1787. She served during the French Revolutionary Wars and fought at the Battle of Groix in 1795 and the Battle of Cape St Vincent in 1797. In December 1798 Colossus was returning from the Mediterranean with wounded sailors and a remarkable cargo that included part of diplomat and antiquarian Sir William Hamilton’s collection. While sheltering in the Isles of Scilly, severe weather drove the ship aground off Samson on 10 December. The ship broke up, but all but one of those aboard survived.

Recovery

The wreck lies in separate bow and stern areas more than 300 metres apart. Material was salvaged soon after the loss, and the bow area received early legal protection in 1975. The stern site was identified in 2001 and is now protected under the Protection of Wrecks Act. Licensed archaeological work has recorded surviving timbers, ordnance, personal objects, and fragments from the classical antiquities cargo. The site remains an active subject of conservation and survey by the Cornwall and Isles of Scilly Maritime Archaeology Society with Historic England oversight.
