He was again promoted, this time to
post-captain on 3 June 1797, and was initially appointed to serve aboard the 114-gun
first-rate , which had been captured at the
Battle of Cape St Vincent. He was then transferred to the 24-gun , aboard which he sailed to
Newfoundland, and then on to
Jamaica, where he remained between October 1798 and January 1800, serving with the squadrons under
Sir Hyde Parker. He was a particularly effective frigate captain, capturing or destroying over 80 armed vessels, privateers and merchants, bringing in an estimated £200,000 in prize money. It was while serving with Parker that Hamilton carried out the most famous act of his career, the cutting-out of the former from the Spanish port of
Puerto Cabello.
Recovering the Hermione by boats from The
Hermione was a former frigate of the Royal Navy, commanded by Captain
Hugh Pigot. In September 1797 a number of the crew had risen up against the apparently tyrannical Pigot and murdered him and nine other officers, throwing their bodies overboard. Fearing retribution for their actions, the mutineers had sailed the
Hermione to the Spanish port of
La Guaira, and handed her over to the authorities. When news of the mutiny reached Parker, he demanded the return of the ship and the surrender of the mutineers, instigating a process that would eventually see the apprehending of 33 of them. The
Hermione meanwhile had been renamed
Santa Cecilia, but remained in port. News eventually reached Parker that the
Santa Cecilia had been sighted in
Puerto Cabello, and ordered the
Surprise to intercept her, should she attempt to put to sea. Hamilton decided that the honour of the
Royal Navy depended on the recovery of the ship, and was determined to retake her. All but three were subsequently returned to the port the next day. Another 15 Spanish escaped by jumping overboard and swimming ashore, while 20 more escaped in a launch that had been guarding the ship. ==Rewards==
