Cornelis Maartensz Tromp, by Abraham Westervelt, 1673. Cornelis Tromp (1629-1691) began his career at sea as a boy, sailing with his father, the famous Admiral Maarten Harpertsz Tromp. Cornelis soon gained promotion in the navy. However, a conflict with Admiral De Ruyter led to a rift and dismissal in 1666. Later, in1673, during the Third Anglo-Dutch War (1672-1674), he resumed his sea service. In 1677-1678 he fought the Swedes in the Baltic. Tromp succeeded De Ruyter in command of the navy in 1678.
