Problem:Question: In what country did King Henry VII's seven year truce originate? Passage 1:Following the defeat of Lieutenant Colonel George A. Custer on June 25, 1876, in the Battle of Little Bighorn, the United States government sent a large number of reinforcements into Montana Territory. By autumn, a few bands of the Sioux and Cheyenne tribes had begun returning to the reservations and agencies to acquire food and annuity goods in preparation for winter. The United States Congress had angered many Indians by demanding that they cede the Black Hills to the government in exchange for these promised goods. The army had replaced civilian contractors in charge of the agencies, further convincing many war bands to stay away from them. General Nelson Miles led a mixed force of infantry, artillery and cavalry after Sitting Bull's band, and had effectively defeated them by December. Ranald S. Mackenzie had similarly defeated Dull Knife's Cheyennes, who trekked through snow and icy conditions to join the camp of Crazy Horse in the Tongue River Valley. Concerned with the approaching winter and the destitute condition of Dull Knife's band, Crazy Horse decided to negotiate peace with the army. However, when a group of United States Army Crow scouts murdered Crazy Horse's delegation, the war chief demanded revenge. He led a series of small raids in an effort to draw out Colonel Miles from Tongue River Cantonment. In December, 1876, Colonel Miles led most of nine Infantry companies out of the Cantonment in pursuit of Crazy Horse, marching south, up the Tongue River valley. On December 7, 1876, Miles captured a few Northern Cheyennes, then his force of 436 men camped along the Tongue just south of present-day Birney, Montana. During that night a fresh layer of deep snow fell and temperatures dropped.
 Passage 2:On October 6, 1957, Bremer Broadcasting announced it had sold its stations for $3.5 million to National Telefilm Associates (NTA), an early distributor of motion pictures for television, joining its NTA Film Network. On May 7, 1958, channel 13's call sign was changed to WNTA-TV to reflect the new ownership; the radio stations also adopted these call letters. NTA's cash resources enabled WNTA-TV to produce a schedule of programming with greater emphasis on the people and events of New Jersey, compared to the other commercial television stations. NTA also sought to make channel 13 the center of a new commercial network, though during its run the NTA Film Network offered only one night of "in-pattern" network programming, Friday nights in 1957–58, and for most purposes WNTA served as the New York showcase for nationally syndicated programming and produced several such entries, notably the anthology drama series Play of the Week; the talk show Open End, hosted by David Susskind; children's show The Magic Clown; and a popular dance program emceed by Clay Cole. The station continued to lag behind New York's other independent stations—WNEW-TV (channel 5), WOR-TV (channel 9) and WPIX (channel 11)—in terms of audience size, and NTA incurred a large debt load. National Telefilm Associates put the WNTA stations up for sale in February 1961.
 Passage 3:Forman and Bishop William Elphinstone of Aberdeen were the principal envoys who brokered a seven-year truce with King Henry VII of England at Aytoun in September 1497. They were assisted by the Spanish ambassador Pedro de Ayala, who recommended in May 1498 that diplomatic correspondence to Scotland should be copied to Forman, his influential friend. The search for a queen for James began in 1499 when negotiators were appointed to treat with King Henry for the marriage of his eldest daughter, Princess Margaret. Dispensation from the pope for the marriage was received as both James and Margaret were cousins, descended from John Beaufort, Marquess of Dorset. On 8 October 1501, Forman, now postulate to the see of Moray, was commissioned along with Robert Blackadder, Archbishop of Glasgow and Patrick Hepburn, 1st Earl of Bothwell to conclude the treaty of marriage. In that same year, King Henry, in gratitude for his services required that Thomas Savage, Archbishop of York institute Forman as Rector of the parish church of Cottingham. On 26 November 1501, Pope Alexander VI provided Forman to the bishopric of Moray and then only a few months later in 1502, Bishop Forman concluded the Treaty of Perpetual Peace with England at Richmond Palace. The formal proceedings that finally concluded the marriage terms of King James and Margaret Tudor were conducted in Glasgow Cathedral on 10 December 1502 where Forman was a signatory. He was then appointed as a commissioner to oversee the exchange of the ratified marriage treaties at the courts of Henry and James. James designated Forman to conduct Margaret to Scotland but while in England, gave King Henry an undertaking that the King of Scots would not renew the league with France unless Henry was first consulted. The procession to Scotland took them to Fast Castle near Berwick where they stayed with Forman's sister Isabel and her husband Alexander Oliphant of Kellie. In 1509, Forman became commendator of Dryburgh Abbey and tried unsuccessfully to obtain the commendatorship of the wealthy abbey of Kelso in 1511. The lands and possessions of the parson of Boleskin, south of Inverness were given to Forman (as bishop of Moray) in 1511 and then in 1512 he became the Keeper of the castle of Darnaway, near Forres, Chamberlain of Moray and Custumar north of the River Spey.
