Prelude to Battle

The kingdom of Matamba, also known as the kingdom of Matamba and Ndongo, lay in what is today eastern Angola. It was created by the warrior queen Nzinga

 via her 1631 conquest of the kingdom from its BaKongo vassal. Throughout the mid-17th century, Queen Nzinga fought a guerilla war against the Portuguese colony of Angola to regain her throne and protect her people, the Mbundu, from the slave trade. By 1657, the queen had regained her traditional capital and ended the wars with Angola in her favor. After her death in 1663, the kingdom she fought so hard to establish devolved into civil war. The war did not end until 1680 when Francisco Guterres Ngola kannini, Njinga's nephew, defeated one of his aunt's former commanders and became king.

The battle

On September 4, 1681, Sequeira arrived at Katole, which was but three day's march from the royal kabasa or palace. He came with over ten thousand infantry and even a small complement of horses (virtually unheard of in Central African warfare). He was met by King Francisco's forces sometime before dawn that day. In the course of the fighting, both Sequeira and Francisco were killed. Matamba's forces retreated, and the Portuguese were able to claim at least a tactical victory by holding their position.

Aftermath

Despite taking the field, which had never been an objective in the first place, the Portuguese losses were such that the invasion of Matamba's capital was called off. After encamping at Katole for nearly thirty days, the Portuguese and their African allies retired to Mbaka under the command of João António de Brito.
