[EX Q]: Question: Who is in charge of the city Couceiro arrived in in 1889? Passage:Paiva Couceiro arrived in Luanda, Angola on September 1, 1889, and was immediately appointed commander of the Irregular Cavalry Squadron in the village of Humpata (which was originally created by Artur de Paiva to combat bands of guerrillas along the plain of Moçâmedes). He did not remain at this outpost for long; apparently he was unsatisfied with his subordinates, their methods and inferior level of discipline, but was able to utilize them in a campaign to retrieve missing cattle, instead of hiring local Boer mercenaries, which had been the custom. By January he was in the village of Belmonte, in Bié, on a mission that would take him along the Cuando River, to Cuito and then to the Lialui along the Zambezi River (a trek of thousands of kilometers across savannah), in order to negotiate with Lewanika, chief of the Barotze tribe. The growth of the Portuguese occupation force in the Angolan interior was part of the administration's attempted to implement their Pink Map to explore and expand their serfdom over the peoples of the central-African interior. After some resistance, the colonial administration began a military campaign to pacify groups that had resisted initial token gestures of friendship and gifts, a process that Paiva Couceiro participated in energetically. For the chief's recognition of Portuguese sovereignty over his territories, Paiva Couceiro brought with him a colonels tunic and sword, textiles, gold, velvet, boxes of Porto wine and arms, which were to be delivered in 300 crates when the Governor of Angola canceled the project.
