Question: How old was Daniel Morgan when Adamson Tannehill was attached to the Provisional Rifle Corps? Passage 1: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.
Passage 2:Friends dissolved shortly afterwards, and Kipner formed a new group, Skyband. Lloyd and Cotton left MGM when Curb also left to establish his own production company. The pair recruited Texan-born Chris Christian, and in 1975 the trio recorded their first album, Cotton, Lloyd & Christian, issued by 20th Century Records. Their version of the Del Shannon song "I Go to Pieces" - a 1965 hit for Peter and Gordon - became a #66 hit on the Billboard Hot 100. Other tracks included a slowed-down version of the Supremes' hit "Baby Love"; a medley of songs from the Who's Tommy; and "I Don't Know Why You Love Me". The album was repackaged by Curb and Lloyd in 1976, and used as the music soundtrack of a movie, The Pom Pom Girls. The trio's second album, Number Two, also appeared in 1976, and in April 1977 they released another single, "Crying in the Rain", written by Carole King and Howie Greenfield and first recorded by the Everly Brothers. Both albums were produced by Lloyd and Curb. No further recordings by the trio were released.
Passage 3:Originally a legendary chronicle written in Anglo-Norman in the thirteenth century (identified by the fact that some existing copies finish in 1272), the Brut described the settling of England by Brutus of Troy, son of Aeneas, and the reign of the Welsh Cadwalader. In this, it was itself based on Geoffrey of Monmouth's text from the previous century. It also covered the reigns of many kings later the subject of legend, including King Cole, King Leir (the subject of Shakespeare's play, King Lear), and King Arthur, and exists in both abridged and long versions. Early versions describe the country as being divided, both culturally and politically, by the River Humber, with the southern half described as "this side of the Humber" and "the better part". Having been written at a time of division between crown and nobility, it was "baronial in its sympathies". It was probably originally composed "at least in part" by clerks in the Royal chancery, although not as an official history. It later became a source for monastic chronicles. Popular already in its early incarnations, it may even have limited the circulation of rival contemporary histories.
