Tromp, Maarten Harpertszoon

Maarten Harpertszoon Tromp (mär´tən här´pərtsōn trômp), 1597–1653, Dutch admiral. A sailor from childhood, he joined the navy and rose to the rank of lieutenant admiral in 1637. In 1639, by remarkable tactics, he was able to blockade and crush a Spanish fleet in the Downs of the English Channel; this defeat marked the passing of Spanish sea power. In June, 1652, his refusal to lower his flag in deference to the English Admiral Robert Blake started the first of the Dutch Wars. He won control of the English Channel by his victory (Dec., 1652) over the English off Dungeness, but he was soon forced to withdraw before superior forces. The inferiority of his fleet caused the loss (June, 1653) of 20 ships near Gabbard Shoal. He effected a union with Witte de Witt's squadron and joined in the attack (Aug., 1653) on the English off Scheveningen. Though Tromp and de Witt were defeated, this action broke the blockade of the Dutch coast and was the last major conflict of the war. Tromp was killed in the battle.

See his Journal Anno 1639 (tr. by C. R. Boxer, 1930).

Citation styles gives you the ability to cite reference entries and articles according to common styles from the Modern Language Association (MLA), The Chicago Manual of Style, and the American Psychological Association (APA).

Within the “Cite this article” tool, pick a style to see how all available information looks when formatted according to that style. Then, copy and paste the text into your bibliography or works cited list.

Because each style has its own formatting nuances that evolve over time and not all information is available for every reference entry or article, cannot guarantee each citation it generates. Therefore, it’s best to use citations as a starting point before checking the style against your school or publication’s requirements and the most-recent information available at these sites:
