English Captain: Thomas Trenchfield

We know that Thomas Trenchfield served in King Charles' navy up until the start of the Civil War. In 1642, he was captain of the 2nd Rate Unicorn (crew 260 men and 769 tons), and served in the Summer Guard for 1642. In 1646, he was a Rear-Admiral in the Parliamentarian navy, and flew his flag on the 2nd Rate Rainbow. There is a note in the House of Commons Journal for 23 February 1646 appointing him as captain of the Rainbow and as Rear-Admiral. His ship was stationed at Chatham. His ship was assigned to the Summer Guard for 1646. He died later in 1646. Sources:
