Cornelis de Witt was a senior Dutch statesman and member of the powerful De Witt family who served as a delegate of the Dutch Republic during the late 1660s and early 1670s. He is recorded in the marine chronicle as the “gevolmachtigde” (deputy) who oversaw the 1667 naval expedition against the English fleet on the River Thames, authorising the landing at Chatham and the subsequent destruction of English warships. Although his direct involvement with the Sultanate of Aceh was limited, his political decisions helped sustain the naval forces that later fought the Dutch‑Aceh wars of the seventeenth century.
Political career
Cornelis, brother of Grand Pensionary Johan de Witt, held the office of Council of State member and was instrumental in financing the Dutch navy during the Second Anglo‑Dutch War. His correspondence, cited in the source (letter dated 23 June 1667), reveals his commitment to aggressive naval action against England, a policy that indirectly affected Dutch overseas operations, including those in the Indian Ocean and the Aceh region.
Role in the 1667 Thames expedition
The source describes how Cornelis de Witt granted the fleet permission to cross the English Channel, sail up the River Thames, and attack the English shipyards at Rochester and Chatham. He coordinated with Lieutenant‑Admiral Michiel de Ruyter and the marine commander François Palm to execute the plan.
Connection to Aceh
While Cornelis never set foot in Aceh, his support for a strong navy enabled the VOC to maintain a presence in the East Indies, where the Dutch fought a series of wars against the Sultanate of Aceh from the 1650s through the 1760s.
