Problem: Background: Born in Scotland on 15 June 1792, he was son of John Mitchell of Carron Works and was brought up from childhood by his uncle, Thomas Livingstone of Parkhall, Stirlingshire. On the death of his uncle, he joined the British army in Portugal as a volunteer, at the age of sixteen. On 24 June 1811, at the age of nineteen, he received his first commission as 2nd Lieutenant in the 1st Battalion 95th Rifles (later the Rifle Brigade / Royal Green Jackets). Utilising his skills as a draughtsman of outstanding ability, he was occasionally employed in the Quartermaster-General's department under Sir George Murray.
Context: In 1831 a runaway convict named George Clarke, who had lived with Aborigines in the area for several years, claimed that a large river called Kindur flowed north-west from the Liverpool ranges in New South Wales to the sea. Charles Sturt believed that the Murray-Darling system formed the main river system of New South Wales and Mitchell wanted to prove Sturt wrong. Mitchell formed an expedition consisting of himself, assistant surveyor George Boyle White and 15 convicts who were promised remission for good conduct. Mitchell took 20 bullocks, three heavy drays, three light carts and nine horses to carry supplies, and set out on 24 November 1831 to investigate the claim. On reaching Wollombi in the Hunter Valley, the local assistant surveyor, Heneage Finch, expressed a desire to join the expedition. He had established his credentials by surveying a route from Sydney to Wollombi, so Mitchell approved his request, provided he obtained extra supplies and men, and he followed along later.  The expedition continued northward, climbed the Liverpool Range on 5 December, and made Quirindi on 8 December. Shortly afterwards Finch arrived but inexplicably had not brought provisions, so Mitchell immediately sent him back to get them. By 11 December the expedition had reached Wallamoul Station near Tamworth, the northern extent of white settlement at the time.  Mitchell continued his northward push into new territory, taking local Kamilaroi people to assist in finding water and to express his peaceful intentions. By early January 1832 he was in the vicinity of the present town of Narrabri, reached the Gwydir River in mid-January, and found the Barwon by the end of the month, where he set up camp. Mitchell left the main party and made a reconnaissance down the Barwon until he found its junction with the Gwydir. After Mitchell returned to the main camp, Finch arrived with tragic news. He had been travelling with three convicts and provisions but, because of a shortage of water, the group had separated. He left two men behind while he attempted to locate the main expedition. Having failed to do that, on the second day he returned to the campsite to discover that it had been ransacked. Supplies were scattered and beneath the wreckage were two dead men. The immediate effect was that Mitchell decided to abandon the expedition and return south. The party reached the Gwydir on 8 February and was near the site of the attack on 17 February. Mitchell buried the two bodies and salvaged some equipment. Once back at Wallamoul, Mitchell placed White in charge of the main party, while he returned hastily to Sydney. He was satisfied that there was no truth about the river Kindur claimed by Clarke. Fourteen years after the attack, Mitchell revealed that the convicts had indulged in sexual relations with Aboriginal women.
Question: Where did the attack happen?
Answer: found the Barwon by the end of the month, where he set up camp.

Problem: Background: Amilcar Lopes da Costa Cabral (Portuguese: [a'milkar 'lopiS ka'bral]; (1924-09-12)12 September 1924 - (1973-01-20)20 January 1973) was a Bissau-Guinean and Cape Verdean agricultural engineer, intellectual, poet, theoretician, revolutionary, political organizer, nationalist and diplomat. He was one of Africa's foremost anti-colonial leaders.
Context: In 1972, Cabral began to form a People's Assembly in preparation for the independence of Guinea-Bissau, but disgruntled former PAIGC rival Inocencio Kani, together with another member of PAIGC, shot and killed him on the 20th January 1973 in Conakry, Guinea. The possible plan was to arrest Cabral (possibly to judge him summarily, later), but facing the peaceful resistance of Cabral, they immediately killed him.  According to some theories, Portuguese PIDE agents, whose alleged plan eventually went awry, wanted to influence Cabral`s rivals through agents operating within the PAIGC, in hope of arresting Cabral and placing him under the custody of Portuguese authorities. Another theory claims that Ahmed Sekou Toure, jealous of Cabral's greater international prestige, among other motives, orchestrated the conspiracy; both theories remain unproven and controversial.  After the assassination, About one hundred officers and guerrilla soldiers of the PAIGC, accused of involvement in the conspiracy that resulted in the murder of Amilcar Cabral and the attempt to seize power in the movement, were summarily executed. His half-brother, Luis Cabral, became the leader of the Guinea-Bissau branch of the party and would eventually become President of Guinea-Bissau.  A declassified United States Department of State brief notes that the motives of his assassination are unclear but may have linked to "a feud between mulattos from the [sic] Cape Verde islands and mainland Africans." Cabral was assassinated prior to the independence of the Portuguese colonies in Africa, and therefore died before he could see his homelands of Cabo Verde and Guinea Bissau gain independence from Portugal.

Problem: Background: Harriet Tubman (born Araminta Ross, c. 1822 - March 10, 1913) was an American abolitionist. Born into slavery, Tubman escaped and subsequently made some thirteen missions to rescue approximately seventy enslaved people, family and friends, using the network of antislavery activists and safe houses known as the Underground Railroad. She later helped abolitionist John Brown recruit men for his raid on Harpers Ferry.
Context: By 1840, Tubman's father, Ben, was manumitted from slavery at the age of 45, as stipulated in a former owner's will, though his actual age was closer to 55. He continued working as a timber estimator and foreman for the Thompson family, who had held him as a slave. Several years later, Tubman contacted a white attorney and paid him five dollars to investigate her mother's legal status. The lawyer discovered that a former owner had issued instructions that Rit, like her husband, would be manumitted at the age of 45. The record showed that a similar provision would apply to Rit's children, and that any children born after she reached 45 years of age were legally free, but the Pattison and Brodess families had ignored this stipulation when they inherited the slaves. Challenging it legally was an impossible task for Tubman.  Around 1844, she married a free black man named John Tubman. Although little is known about him or their time together, the union was complicated because of her slave status. Since the mother's status dictated that of children, any children born to Harriet and John would be enslaved. Such blended marriages - free people of color marrying enslaved people - were not uncommon on the Eastern Shore of Maryland, where by this time, half the black population was free. Most African-American families had both free and enslaved members. Larson suggests that they might have planned to buy Tubman's freedom.  Tubman changed her name from Araminta to Harriet soon after her marriage, though the exact timing is unclear. Larson suggests this happened right after the wedding, and Clinton suggests that it coincided with Tubman's plans to escape from slavery. She adopted her mother's name, possibly as part of a religious conversion, or to honor another relative.
Question: Where did Tubman go when she escaped?
