Question: How many years did the war last that coincided with Bracton's retirement? Passage:Plucknett describes Bracton in this way: "Two generations after Ranulf de Glanvill we come to the flower and crown of English jurisprudence – Bracton." Bracton was born around 1210 in Devon and had a great deal of preferment in the Church. He either derived from Bratton Fleming or Bratton Clovelly. Both villages are in Devon. It was only after his death that the family name appears as Bracton; during his life, he was known as Bratton, or Bretton. This originally may have been Bradton, meaning "Broad Town". Bracton first appeared as a justice in 1245. From 1248 until his death in 1268 he was steadily employed as a justice of the assize in the southwestern counties, especially Somerset, Devon and Cornwall. He was a member of the coram rege, also called the coram ipso rege, later to become the King's Court. He retired from this in 1257, shortly before the meeting of the Mad Parliament in 1258 at Oxford. It is unknown whether his retirement was related to politics. His leaving coincided with the onset of the notorious Second Barons' War in 1264. At that time Bracton was ordered to restore to the Treasury the large store of plea rolls (case records from previous trials) that had been in his possession. He was also forced to surrender the large number of rolls from his predecessors Martin Pateshull and William Raleigh, also known as William de Raley. It cannot be determined whether he disgraced the King or the barons in this affair, but it is speculated that some kind of political intrigue was involved. The practical result was that his major work, De Legibus et Consuetudinibus Angliae ("The Laws and Customs of England"), was left unfinished. Even so, it exists in four large volumes today. He continued to follow the assizes in the southwest until 1267. In the last year of his life he filled another prominent role, as member of a commission of prelates, magnates and justices appointed to hear the complaints of the "disinherited" – those who had sided with Simon de Montfort, 6th Earl of Leicester.

Question: How many professional boxers did Garcia train? Passage:Despite being forced to retire from pro boxing Díaz kept in shape by lifting weights at a local gym. The gym owner was impressed with Díaz physique and work ethics and recommended he become a luchador. Díaz was originally trained by Ray Carrasco and later also trained under Rogelio de la Paz, Genaro Contreas, Raul Rojas and Daniel García; the latter would later be famous under the name of "Huracán Ramírez". Díaz made his professional wrestling debut in 1954, using the ring name "El Pelón" (Spanish for "Baldy") Chato Díaz, then later on worked under names such as "Indio" Mendoza, El Rayo Rojo and El Hombre del Rayo Rojo. He also worked for a while as an enmascarado (masked) character called Gargantua between 1954 and 1955. In 1955 Díaz came up with the ring name "Ray Mendoza" after his mentor Ray Carrasco and his wife's maiden name Mendoza. As Mendoza he quickly forged a very effective Rudo character ("bad guy") by using well developed physique and charisma to create a ring character that the fans loved to hate. In 1956 Mendoza began working for Salvador Lutteroth's Empresa Mexicana de Lucha Libre (EMLL), the world's oldest and Mexico's largest wrestling promotion. He made his debut at EMLL's main arena Arena Coliseo in February, 1956 in a Battle Royal that also included EMLL headliners Gory Guerrero, El Santo, Cavernario Galindo, Blue Demon and Black Shadow, a match that immediately established him as someone who Lutteroth saw potential in. In EMLL Mendoza struck up a friendship with René Guajardo and Karloff Lagarde out of the ring and a "partnership in crime" in the ring as the three became one of the most hated trio in lucha libre at the time. The three drew full houses all over Mexico, setting box office record after box office record as they faced técnicos(good guys) such as El Santo, Rayo de Jalisco or Blue Demon. They also had a very financially successful feud with Los Espantos (Espanto I, Espanto II, and Espanto III) in what at the time was a rare rudo vs. rudo feud. Outside the ring Mendoza, Guajardo and Lagarde often spoke out on behalf of the wrestlers, demanding higher pay and better conditions, and since they were able to generate a lot of ticket sales EMLL officials listened to their demands.

Question: Who was the first architect of the building Barton completed after the Mexican-American War? Passage:Barton Stone Alexander (September 4, 1819 – December 15, 1878) was a Union Army lieutenant colonel, engineer regiment commander and chief engineer for the defenses of Washington during the American Civil War. In recognition of his service, in 1866, he was appointed to the brevet rank of brigadier general in the regular army, to rank from March 13, 1865. He was a graduate of the U.S. Military Academy at West Point and served in the United States Army's Corps of Topographical Engineers, which at times was both a part of and separate from the United States Army Corps of Engineers. After graduating from West Point as a second lieutenant in the Class of 1842, he served in the Mexican–American War, building fortifications to protect American supply lines in the advance on Mexico City. After the end of the war, he was stationed in Washington, D.C., where he served as architect for the Scott Building and Quarters Buildings at the U.S. Soldiers' Home and took over the completion of the Smithsonian Institution Building after dissatisfaction with the pace of the first architect caused him to be dismissed.
