In September 1674, the King appointed him lieutenant of the 4th Rate Dragon. Finally, on 16 January 1678 (under the old system, they called it 1677), the King appointed him as captain of the Sixth rate Drake. On 3 April 1680, he was given command of the prize Orange Tree. On 13 April 1682, he was reappointed to command the Orange Tree. On 18 April, he was switched to the Mermaid. On 23 February 1684 (again, they called it 1683), he was appointed to command the Oxford. On 1 June 1684, the King appointed John Tyrrell to command the Phoenix of 42 guns. On 19 September 1685, he caught and sank a "Zanganian" pirate ship in an action notable for the boarding and survival of then Lieutenant John Byng.
Then on 4 September 1688, he was appointed to command the Mordaunt (46 guns). He took part in the action on 4 October 1689, when a group of English cruisers fell in with 12 French warships, and the 6th Rate Lively prize was lost. He commanded the Third rate Anne (70 guns) when she was beached and burnt after the Battle of Beachy Head in 30 June 1690, "where he withstood the violence of the whole French navy". He had been assigned to the rear (Blue) squadron. He fought at the Battle of Barfleur, where he commanded the Second rate Ossory (90 guns).
He died 6 December 1692, aged 46, and according to his memorial in Oakley he was a true lover of his country, a valiant and skilful Commander.
