The Attack on Aruba was an attack on oil installations and tankers by Axis submarines during World War II. On 16 February 1942, a German U-boat attacked the small island of Aruba. Other submarines patrolled the area for shipping and they sank or damaged tankers. Aruba was home to two of the largest oil refineries in the world during the war against the Axis powers, the Arend Petroleum Maatschappij, situated near the Oranjestad harbor and the Lago Oil and Transport Company at the San Nicolas harbor. The attack resulted in the disruption of vital Allied fuel production.
