Maarten Tromp - Supreme Commander of The Confederate Fleet

Supreme Commander of The Confederate Fleet

Tromp was promoted from captain to Lieutenant-Admiral of Holland and West Frisia in 1637, when Lieutenant-Admiral Philips van Dorp and other flag officers were removed for incompetence. Although formally under the Admiral-General Frederick Henry of Orange, he was in fact supreme commander of the Dutch fleet, as the stadtholders never fought at sea. Tromp was mostly occupied in blockading the privateer port of Dunkirk.

In 1639, during the Dutch struggle for independence from Spain, Tromp defeated a large Spanish fleet bound for Flanders at the Battle of the Downs, marking the end of Spanish naval power. In a preliminary battle, the Action of 18 September 1639, Tromp was the first fleet commander known to deliberately use line of battle tactics. His flagship in this period was the Aemilia.

In the First Anglo-Dutch War of 1652–1653 Tromp commanded the Dutch fleet in the battles of Dover, Dungeness, Portland, the Gabbard and Scheveningen. In the last of these, he was killed by a sharpshooter in the rigging of William Penn's ship. His acting flag captain, Egbert Bartholomeusz Kortenaer, on the Brederode kept up fleet morale by not lowering Tromp's standard, pretending Tromp was still alive.

The death of Maarten Tromp was not only a severe blow to the Dutch navy, but also to the Orangists who sought the defeat of the Commonwealth of England and restoration of the Stuart monarchy; Republican influence strengthened after Scheveningen, which led to peace negotiations with the Commonwealth, culminating in the Treaty of Westminster.

During his career, his main rival was Vice-Admiral Witte de With, who also served the Admiralty of Rotterdam (de Maze) from 1637. De With temporarily replaced him as supreme commander for the Battle of Kentish Knock. Tromp's successor was Lieutenant-Admiral Jacob van Wassenaer Obdam.

Tromp, a "sea hero", was immensely popular with the common people, a sentiment expressed by the greatest of Dutch poets, Joost van den Vondel in a famous poem describing his marble grave monument in Delft showing the admiral on his moment of death with a burning British fleet on the foreground:

Here rests the hero Tromp, the brave protector

of shipping and free sea, serving free land

his memory alive in artful spectre

as if he had just died at his last stand

His knell the cries of death, guns' thunderous call

a burning Brittany too Great for sea alone

He's carved himself an image in the hearts of all

more lasting than grave's splendour and its marble stone

Also the second son of Tromp and his first wife, Dignom Cornelisdochter de Haes, Cornelis Tromp, became later commander of the Dutch navy, as Lieutenant-Admiral-General, and he commanded earlier the Danish navy.
