Cort Sivertsen Adeler

Cort Sivertsen Adeler (1622–1675) was a Norwegian-born seaman who entered the Dutch navy at fifteen and fought at the Battle of the Downs in 1639. From 1642 he served aboard a Dutch ship hired by Venice, becoming its captain in 1645 and flag captain in 1650.

On 13 May 1654 his ship broke the Turkish galley line near the Dardanelles and sank fifteen galleys; Tenedos surrendered to him the following day. Ennobled by Denmark in 1666, he led the Dano-Norwegian fleet until his death at Copenhagen in 1675.
