Jacob Willekens or Wilckens (1564 – 1649) was a Dutch admiral on a fleet to the Dutch Indies, and a herring seller, who went to sea again at the age of fifty for the Dutch West Indies Company. His most well-known success was undoubtedly the conquest of San Salvador de Bahia, the then capital of Brazil. His fleet, which included Dutch corsair Piet Hein as vice admiral, departed from Texel on December 22, 1623 with between 26-36 ships and 3,300 sailors towards South America. At the beginning of June 1624, they began their attack from sea and soon captured the Portuguese stronghold with little resistance. They occupied Bahia for over a year before the local population took up arms under acting governor Matias de Albuquerque and Archbishop Dom Marcos Teixeira who eventually expelled them with the help of a combined Spanish-Portuguese fleet numbering 52 warships and 12,000 soldiers in May 1625. This was the first major WIC privateering expedition to the region.
