Wreck of HMS Racehorse 1822.
[from Sun (London) - Tuesday 09 July 1844]:
SUBMARINE OPERATIONS. - On Thursday week, the smack Argyle, of Jersey,
belonging to a company in the West of England, arrived in
Castletown-bay, Isle of Man, with a celebrated diver, apparatus, &c.,
for the purpose of taking up the brass guns and other parts of the wreck
of the Racehorse sloop-of-war, lost on Langness-point, about 21 years
ago. On Wednesday last a great number of people, gentle and simple,
were out at Langness, looking at the diver. The weather was beautiful,
and there were persons sailing on the sea who had not been on the water
for many years. There was not a single boat left in the harbour. The
diver has succeeded, with the assistance of the crew of the Argyle, in
taking up about 30 tons of pig-iron, a large quantity of copper, and a
large anchor and chain. The diver was under water three hours at one
time on Wednesday.
[Thanks to Adrian Corkill for alerting me to this - he notes that
HMS Racehorse, wrecked at Langness, had iron guns]
