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.

Question: Who was Roland I's mother? Passage:Roland I was born around 1215 into the gens Rátót as the son of Dominic I, who served as Master of the treasury from 1238 to 1240. He was killed in the Battle of Mohi in 1241. The ancestors of the kindred were two Norman knights (Oliver and Rathold) from Caserta, Naples, who settled down in Hungary around 1097 during the reign of Coloman, King of Hungary. Roland's earliest known ancestor was his great-grandfather Leustach I Rátót, Voivode of Transylvania in the second half of the 12th century. Roland had three brothers, Stephen, the forefather of the Pásztói, Tari and Kakas de Kaza noble families. The Putnoki family came from Oliver I.

Question: How many german forces were in these regions? Passage:During World War I (1914–18) an expanded Force Publique served against German colonial forces in the Camerouns and German East Africa (Tanzania, Rwanda, Burundi), as part of the East African Campaign. The Force Publique performed well on the battlefield, winning the respect of their British and Portuguese allies, as well as that of their German opponents. 1916 onwards, the Force Publique grew to reach a strength of three mobile Groupes (brigades), Kivu, Ruzizi, and Tanganyika, comprising a total of 15 battalions, from the static garrison and police force of 1914. However, it did take until late 1915 for the Force Publique to finish preparations for a large scale offensive on the German colony of German East Africa. The allied powers, the British Empire and Belgium launched a coordinated attack on the German colony, by 1916 the Belgian commander of the Force Publique, Lieutenant-General Charles Tombeur, had assembled an army of 15,000 men supported by local bearers and advanced to Kigali. Kigali was taken by 6 May 1916. The German army stationed in Burundi was forced to retreat by the numerical superiority of the Belgian army and by 17 June 1916, Burundi and Rwanda were occupied. The Force Publique and the British Lake Force then started a thrust to capture Tabora, an administrative centre of central German East Africa. The army went on to take Tabora on 19 September after heavy fighting. At the time of the Battle of Tabora in September 1916 about 25,000 men were under arms, during the war their actions were supported by more than 260,000 local bearers. In 1916 Charles Tombeur was made Military Governor of the Belgian Occupied East African Territories. After the Mahenge Offensive and the capture of Mahenge in 1917, the Belgian Congolese army controlled roughly one-third of German East Africa. After the war, as outlined in the Treaty of Versailles, Germany was forced to cede "control" of the Western section of the former German East Africa to Belgium. On 20 October 1924, Ruanda-Urundi (1924–1945), which consisted of modern-day Rwanda and Burundi, became a Belgian League of Nations mandate territory, with Usumbura as its capital.
