1640s in Angola

From August 26, 1641 to August 21/24 1648 the Dutch occupied the coastal areas (under a governor of Dutch West India Company) of Angola. This attack was the culmination of a plan first proposed by Kongo's King Pedro II in 1622. After the Dutch fleet under Admiral Cornelis Jol took Luanda, the Portuguese withdrew to the Bengo River, but following the renewal of the Kongo-Dutch alliance, Bengo was attacked and subsequently Portuguese forces withdrew to Massangano. The Dutch were not interested in conquering Angola, much to the chagrin of Kongo's king Garcia II and Njinga who had both pressed them to assist in driving the Portuguese from the colony. However, Dutch authorities came to realize that they could not monopolize the slave trade from Angola just by holding Luanda and a few nearby places, and moreover, the Portuguese sent several relief expeditions to Massangano from Brazil. Consequently in 1647, the agreed to reinforce Njinga's army following her defeat by Portuguese forces in 1646. At the Battle of Kombi Dutch and Njinga's armies crushed a Portuguese army and in its aftermath laid siege to Ambaca, Massangano and Muxima. However, a larger and stronger relief from Brazil, led by Salvador Correia de Sa, took Luanda and the Dutch capitulated and evacuated Angola.
