[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 Mocamedes). 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 Bie, 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.

Passage:As a boy, Roebuck worked as a trammer and after being sentenced to one month's imprisonment for stealing a watch in 1904, he enlisted in the York and Lancaster Regiment. Over the next seven years, he was stationed in India and Ireland and was promoted to lance corporal, but was demoted back to private in 1910 for "misconduct". He married in 1908 and had two children.

After Britain's entry into the First World War in August 1914, he was called up by the York and Lancaster Regiment and arrived on the Western Front in September 1914. On 18 October 1914, Roebuck recorded as "presumed dead" after an attack near Beaucamps-Ligny during the Race to the Sea. His death was confirmed by two comrades in January 1915.

Fuller was repeatedly in contention with the ecclesiastical courts, including the Star Chamber and Court of High Commission, and was once expelled for the zeal with which he defended his client. In 1593 he was returned as the Member of Parliament for St Mawes, where he campaigned against the extension of recusancy laws.
