Question: Question: How many years had Fort Pitt existed when Tannehill was assigned there? Passage:Tannehill served in the Continental Army during the American Revolutionary War, initially as the first sergeant in Capt. Thomas Price's Independent Rifle Company, one of the original ten independent companies of riflemen from the frontier regions of Pennsylvania, Maryland, and Virginia authorized by the Continental Congress on June 14, 1775. He received his commission dated January 1, 1776, as a third lieutenant while serving at the Siege of Boston. In June 1776 Tannehill and his company were incorporated into the newly organized Maryland and Virginia Rifle Regiment, at which time he advanced to second lieutenant. Later that year a large portion of his regiment was captured or killed at the Battle of Fort Washington on northern Manhattan Island. However, those members of the unit not taken in the battle, including Tannehill, continued to serve actively with Washington's Main Army, participating in the Battles of Trenton and Princeton, and in the spring of 1777 were administratively attached to the 11th Virginia Regiment. Tannehill was promoted to first lieutenant on May 18, 1777, and the following month he was attached to the newly organized Provisional Rifle Corps commanded by Col. Daniel Morgan, which played a major role in the Battles of Saratoga and a peripheral role in the Battle of Monmouth. He returned to the Maryland and Virginia Rifle Regiment (his permanent unit) in mid-1778 when Lt. Col. Moses Rawlings, the regiment's commander who had been exchanged from British captivity earlier that year, was marshaling the remnants of his unit and recruiting new members while stationed at Fort Frederick, Maryland. In early 1779 Tannehill and the regiment were assigned to Fort Pitt of present-day western Pennsylvania where they supplemented other Continental forces engaged in the defense of frontier settlements from Indian raids. Tannehill advanced to the rank of captain on July 29, 1779, and he commanded the regiment in late 1780. He was discharged from service on January 1, 1781, when his unit was disbanded.


Answer: In early 1779 Tannehill and the regiment were assigned to Fort Pitt of present-day western Pennsylvania where they supplemented other Continental forces engaged in the defense of frontier settlements from Indian raids


Question: Question: What city was Leaton in when he gave his acceptance speech at the UN headquarters? Passage:He won significant critical attention in 2006 when he was awarded the grand prize of the 2006 Film Your Issue competition, judged by President Barack Obama, George Clooney and the Dalai Lama, among others. Leaton presented his winning film Orphans in Africa and gave acceptance speeches, covered by the press, at three awards ceremonies: at the United Nations Headquarters where he was introduced by the President of USA Today, then again in Hollywood where he was introduced by the Mayor of Los Angeles, and finally during Sundance in Park City with Kevin Bacon and Mandy Moore. Leaton also received the 2006 grand prize Walt Disney Pictures paid internship. His mentors included some of the top executives, and he began getting hands-on experience on various Disney films. Years later when Lindsey Brookbank of the Collegiate Times asked him what his favorite memory was from his grand-prize internship, he replied "Having dinner with Roy Disney on board the Queen Mary." According to Brookbank, this internship gave Leaton the connections and experience that would help him land jobs in Hollywood after finishing college. He returned to Film Your Issue as a member of the jury the following year, and has also judged other student film contests.

Question: Question: How long is the Tsarigrad Road in total? Passage:The garden already existed at least in the early 18th century. During the Austrian occupation of northern Serbia 1717-39, several hospitals were established in Belgrade, including the Great military hospital. Based on the Austrian plans, the hospital was set outside of the Belgrade Fortress ("Danubian" or "German Belgrade"), in the Serbian part of the city. As shown on the map of Belgrade by Nicolas François de Spar, the Tsarigrad Road began at the Württemberg Gate (Stambol Gate), at the modern Republic Square, and headed towards "Marko's cemetery" in Tašmajdan. The hospital was situated on the road's right side, where the modern Stari Dvor is located. Behind the hospital there was a large garden, predecessor of the modern park, and further behind it, across the road was the military cemetery. Later "Marko's market" developed on the spot and today it is the area surrounding the House of the National Assembly of Serbia. After Austria lost the Austro-Turkish War of 1737–1739, the northern Serbia, including Belgrade, was returned to the Turks. One of the provisions of the 1739 Treaty of Belgrade stated that Austria had to demolish all the fortifications and military and civilian buildings it has constructed during the occupation. Many Baroque buildings were demolished. However, Austria didn't demolish the buildings outside of the fortress walls, including the Great military hospital, which, albeit as a ruin, survived until the next Austrian occupation in 1788.
