Étienne Cochard de Chastenoye (died c. 1749) was a French colonial soldier who was interim governor of Saint-Domingue (Haiti) three times in the 18th century.
[9] On 22 March 1748 a squadron of British ships under Admiral Charles Knowles entered the harbor of Port Saint Louis, which was guarded by an island castle with 24 feet (7.3 m) high stone walls, 78 guns, 310 troops and a company of black gunners.
In the Battle of Saint-Louis-du-Sud, the British ships anchored under the ramparts and fired steadily for three hours, causing 160 casualties to the garrison.
[7] On 17 January 1749 Chastenoye wrote to the minister Jean-Frédéric Phélypeaux, Count of Maurepas pointing out the commercial losses of the planters during the recent war and the expense of supplying blacks to work on the defenses, and calling for protection for their trade.
[11] His son, Achille Cochart, marquis de Chastenoye, was appointed governor of La Cap on 1 November 1749.
[12] According to Médéric Louis Élie Moreau de Saint-Méry, Chatenoye earned the respect of the officers and the confidence of the settlers everywhere in the course of his long career.
