HMS Colossus Investigation 2015

Project 7157 Report

By Kevin Camidge (main author)

This report covers the findings from an investigation by Cornwall and Isles of Scilly Maritime Archaeology Society (CISMAS) in 2015 of an area of archaeological material to the east of the stern of the Protected Wreck of the warship HMS Colossus, which sank in 1798.

Among the finds were elements of the ship's rigging, parts of a gun carriage, a group of uniform buttons and a remarkable miniature cannon.

A number of questions were raised by the material found; this has led to a reappraisal of the wrecking process of Colossus. The report suggests a new theory of how the current disposition of remains came about and makes suggestions as to how this new theory can be tested.

The report was prepared on behalf of Historic England by Kevin Camidge, with contributions from Jezz Davies, Mags Felter and Damien Sanders (Cornwall and Isles of Scilly Maritime Archaeology Society (CISMAS)) as well as Polydora Baker and Gill Campbell (Historic England staff). The project was also advised by Alison James of Historic England.
