Whetstone was probably born in the Netherlands. His father was an army officer, and his mother was the favourite sister of Oliver Cromwell. During the
Interregnum, Whetstone volunteered for naval service on the expedition to
Hispaniola in 1654. Because of pressure from the Lord Protector, Whetstone went from volunteer to
lieutenant to command of a ship called
Golden Cock on his return to England. In 1656, he was put in command of
Phoenix and then
Fairfax the next year. In 1657, he was put in command of a squadron in the Mediterranean. Acting as a privateer, Whetstone disobeyed direct orders and sold a prize ship of grain for his own profit. When his command was revoked in response, Whetstone deserted and sailed his ship for
Algiers. Oliver Cromwell's support was unswayed, however. In 1658, Whetstone was supposed to lead a command of ships that would collaborate with the
French in an attack on Spain. He stayed in port, however, quarrelling and trading, and the venture never formed. When Cromwell died in September 1658, Whetstone was relieved of command and taken prisoner. of thirteen privateers, and the next year he was the speaker of
House of Assembly of Jamaica. His forces seized the Spanish-held
Providence Island in 1666, but the Spanish retook the island and sent Whetstone, in chains, to
Panama. He was eventually released from prison, but his name disappears from public records around 1668. It is presumed that he died in that year. ==References==
