Domingo, which was due to a panic among the troops. Afterwards, English forces seized the less desirable island of Jamaica for the Commonwealth régime, and Penn established the Jamaica Station there. On their return, he and his military colleague, Robert Venables, were sent to the Tower. He made a humble submission, and when released retired to the estates of confiscated land he had received in Ireland. On 20 December 1658, Penn was knighted by Henry Cromwell at Dublin Castle, but the Protectorate honour passed into oblivion at the Restoration in May 1660. Political career In April 1660, Penn was elected as one of the Members of Parliament for Weymouth and Melcombe Regis and sat in the Convention Parliament. He played a small part in the Restoration: in May 1660 he was on the Earl of Sandwich's ship, the Naseby (later the Royal Charles), which was sent to bring King Charles II home to England from his exile at Amsterdam in the Dutch Republic. During the voyage, Penn made himself known to the Duke of York, who was soon to be appointed Lord High Admiral, and with whom he had a lasting influence. In 1661, Penn was re-elected as a member for Weymouth and Melcombe Regis in the Cavalier Parliament.

Although Penn was not a high-minded man, he is a figure of considerable importance in English naval history. As admiral and General at Sea for Parliament, he helped in 1653 to draw up the first code of tactics provided for the English navy, Duties of a Commander at Sea, 1664, Instructions by Sir W. Penn. It became the basis of the "Duke of York's Sailing and Fighting Instructions", which continued for long to supply the orthodox tactical creed of the navy. Penn was an early proponent of fighting in line ahead, so as to bring as much firepower as possible to bear. Legacy A key source for the adult life of Penn is the diary of his colleague at the Navy Board, and next door neighbour in Seething Lane, Samuel Pepys. However, Pepys's assessments have to be tempered by the jealousy that he evidently held for Penn. In 1660,
