The battle resulted in a Spanish defeat.

　　In 1569, the Spanish occupied Amsterdam, and Dutch resistance against the occupation emerged throughout the Netherlands, finally blossoming into a war for independence. The Dutch war on the seas was carried out by rebel sailors who called themselves the Sea Beggars, and who regularly disrupted Spanish shipping to Amsterdam through the Zuiderzee. Seeking to crush this seaborne rebellion, the Spanish sent a fleet of thirty ships into the Zuiderzee under the command of Maximilien de Hénin-Liétard, Count of Boussu (1542–1578), the Walloon head of all Spanish forces in the Netherlands.

　　Britannica Quiz World Wars On October 11 Boussu met the Sea Beggars between the towns of Hoorn and Enkhuizen. The Dutch commander, Admiral Kornelius Dirkszoon, had five fewer ships than the Spanish, and they were smaller and more lightly armed than the Spanish vessels. Under a strong easterly breeze, the Sea Beggars bore down on the Spanish and captured five of their ships. Most of the other Spanish ships fled, leaving only Boussu’s flagship, the heavily armored Inquisition. Four Dutch ships attacked the Inquisition. One was destroyed immediately. The other three grappled to the larger ship, locking the four ships together. A bitter hand-to-hand struggle commenced. Boussu drove back the boarding parties with boiling oil and molten lead.

　　At sunset, the four ships struck a shoal, and the combat continued through the night. At dawn, a Sea Beggar managed to climb on board and tear down the Inquisition’s colors, but he was shot down after doing so. By now, the Sea Beggar ships were receiving fresh supplies of men and ammunition, and Boussu realized his position was untenable. He surrendered his men and his ship, and he and his surviving crew were taken prisoner. On being released under the terms of the Pacification of Ghent in 1576, Boussu defected to the rebel side and became commander of the Dutch forces in the War of Independence.

　　In 2020, Dutch maritime archaeologists discovered the wrecks of 34 ships believed to have taken part in the Battle on the Zuiderzee. A program of underwater salvage and excavation is ongoing.
