here is some info on that prison that I just found
Specific research into prison hulks has received very
little archaeological attention. The Dromedary project
is the only work cited here which utilizes prison hulks
as an archaeological resource (Addams & Davis, 1998;
Addams & Newell, 1999). The Dromedary, (formerly a
New Zealand service ship), was one of the eight known
hulks to be moored on Ireland Island, Bermuda in 1826.
Initiated in the early 1980s, the Dromedary archeological
project has excavated a series of trenches immediately
below the site of the hulk in the Bermuda Dockyard.
From these excavations, a significant artefact assemblage
has been collected. Including horse and beef bones,
buttons, jewellery, bone utensils, clay pipes and carved
limestone figures, the analysis of which has given insight
into the material culture of the prison hulk.
