Hi Bart,Hey Thorkil,
I don't know what's wrong if spelled with an "u", but this Tromp was well-known to the Danish as well.
From Wikipedia (Google translation ... )
All the best.
Even though I then ought to sort of be in solidarity with Tromp, because of defeating the Swedish fleet in a battle south of Öland in 1676 (and sea-wise, while an old old silly man has claimed I'm descended from an Jakob Bagge who was Swedish admiral and won a battle against the Danes at the see by Bornholm in 1563 but after a battle with the Danes around the same Öland he was captured and held as prisoner in Copenhagen under rather large freedom - perhaps the freedom was as large as its why I'm sitting here, who knows, but at that time I unfortunately lost interest listening to the old man, and now I guess he might be dead), but the danish Wikipedia mention that Tromp seemed to be rather brutal, and unpopular in his homeland. He terrorized the French coastline before getting hired by the Danes, and while he tried to get dutch help to the Danes in the war affairs with Sweden, he came too late back to Copenhagen, and by that time the danish admiral Niels Juul had already at 1. July 1677 won against a superior Swedish fleet in Köge Bugt south of Copenhagen. And because of his rude and insisting behavior against his superiors admirals and the captains, the king Christian V seems to lost patience and dismissed Tromp in 1678.
(I guess the same story will differ from country to country)
