Fort Jemseg, a French fortified trading post located on the east bank of the Jemseg River in what now is New Brunswick, was briefly conquered by Dutch Frigate captain Jurriaen Aernoutsz, commanding the Vliegende Paert van Curacao, in 1674, during the Franco-Dutch War. After conquering the French fort Pentagouet further south in what is now Castine, Maine (US), Aernoutsz sailed on to Fort Jemseg and also captured that fort. Returning south, Aernoutsz sold the guns (tout le canon) of Fort Pentagouet in Boston to governor John Leverett of the Massachusetts Bay Colony. Before interested parties from New York, such as Cornelis Steenwijck and John Rhoade, could enforce the Dutch claim, the English briefly took possession before the area returned to French rule. Most of the documents related to the Dutch attack on Acadia deal with the aftermath and contain little detail about the capture of Fort Pentagouet and Fort Jemseg or of the material condition of the fortifications. It is clear however that the activities of the Dutch forces during their brief stay were mostly of a destructive nature.
