Tannehill was an early citizen of Pittsburgh and a Pennsylvania politician who held several local, state, and national appointed and elected offices. These included one term as a Democratic-Republican in the U.S. House of Representatives from 1813 to 1815 and president of the Pittsburgh branch of the Bank of the United States starting in 1817 until his death in 1820. He also served on the founding boards of several civic and state organizations. In late 1800, Tannehill, while a justice of the peace, was alleged to have charged more than was allowed by law for two probates and was convicted of extortion. He was reinstated to office shortly after by the governor of Pennsylvania.
Tannehill died in 1820 near Pittsburgh, Pennsylvania. He was buried at his Grove Hill home outside Pittsburgh and reinterred in Allegheny Cemetery in 1849.
Early years
Adamson Tannehill was born May 23, 1750, in Frederick County, Maryland,[1][2] the oldest of nine children born to John Tannehill, owner of a tobacco plantation, and Rachel Adamson Tannehill.[2] Adamson's maternal grandfather took a special interest in the grandchild who bore his name, and he provided "such pecuniary assistance as to secure a fine education" for him.[3] Little else is known of Adamson's youth and upbringing. No portraits of him are known to exist; family records state that as an adult he "was six feet in height, well proportioned and of commanding appearance".[4]
Revolutionary War service
A Continental Army officer's commission for Third Lieutenant "Adamson Tannehill, Gent[leman]" of Captain Otho Holland Williams' Independent Rifle Company, dated January 1, 1776. The document is signed by Charles Thomson, secretary of the Continental Congress and by John Hancock, president of Congress. Williams had replaced Thomas Price as captain of the company in late 1775
At the age of 25, Tannehill was among the first volunteers to enlist in one of the earliest American military units to form when the American Revolutionary War started in the spring of 1775.[5] He served in the Continental Army, initially as a sergeant in Captain Thomas Price's Independent Rifle Company,[5] one of the original ten independent rifle companies from Pennsylvania, Maryland, and Virginia authorized by the Continental Congress on June 14, 1775.[6] He received his officer's commission dated January 1, 1776, as a third lieutenant,[7] while serving at the siege of Boston.[3][8] In mid-June the same year, Tannehill and his company were incorporated into the newly organized Maryland and Virginia Rifle Regiment, when he advanced to second lieutenant.[9] In the summer and fall of 1776, many of the regiment's officers, including Tannehill, conducted recruitment and initial training of new enlistees in the two states and moved them to New York to join the regiment.[10]
On November 16, 1776, a large portion of Tannehill's regiment was captured or killed at the Battle of Fort Washington on northern Manhattan Island.[11] The remainder—about one-third of the unit including Tannehill—continued to serve actively in the Continental Army.[12] That winter, they participated in the battles of Trenton, Assunpink Creek, and Princeton and in the early 1777 skirmishing in northern New Jersey, a period termed the Forage War.[13][14] The following spring, they were administratively attached to the 11th Virginia Regiment because of the losses suffered by their rifle regiment.[15] The riflemen also provided an experienced, if small, force to bolster this newly formed Virginia unit.[16] Tannehill was promoted to first lieutenant on May 18, 1777,[17] and the following month he was attached to the newly organized Provisional Rifle Corps commanded by ColonelDaniel Morgan.[18] Deployed as specialized light infantry, this regiment-size force of about 500 riflemen played a major role in the Battles of Saratoga and the Battle of White Marsh in late 1777 and a peripheral role in the Battle of Monmouth in June 1778. The rifle corps was also notable for its scouting and outpost duties in defense of the Continental Army's Valley Forge encampment during the winter and spring of 1777–1778.[19]
Tannehill was detached from the rifle corps after the Battle of Monmouth in mid-1778 and returned to the Maryland and Virginia Rifle Regiment (his permanent unit).[19] This occurred when Lieutenant ColonelMoses Rawlings, the regiment's commander, was marshaling the remnants of his unit and recruiting new members while stationed at Fort Frederick, Maryland.[20] (Rawlings had been captured at the Battle of Fort Washington and recently exchanged from British captivity.)[21] In furtherance of Rawlings' effort to muster the members of his regiment, General George Washington ordered in early 1779 that "all the men belonging to…Rawlings's Regimt. now doing duty in the line are to be delivered up to Lieutenant Tanneyhill [sic] of said regiment upon his demanding them."[22] Tannehill supervised the assembly of the regiment because of the temporary absence of its acting commander.[23]
Signature of 30-year-old Adamson Tannehill, "Captain Comdg Md Corps", from a return (troop tally) taken at Fort Pitt on December 25, 1780. For administrative reasons, by 1779 his regiment comprised mostly riflemen from Maryland and was commonly known as the "Maryland Corps"
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 of the war's western front from Indian raids.[24][25][26] The high mark of this effort, in which Tannehill and his regiment took part,[27] was the 605-man Brodhead Expedition against hostile Mingo and Munsee Indians along the upper reaches of the Allegheny River conducted in the late summer of 1779.[28][29] Continental Army Western Department commander Colonel Daniel Brodhead considered the Iroquoian Mingo to be "the principal distressers of [the] settlements" at that time, especially north and west of Fort Pitt.[30] Consequently, the rifle regiment was also deployed in detachments to support Continental infantry contingents at Fort McIntosh,[31]Fort Laurens,[32]Holliday’s Cove Fort,[33] and Fort Henry[34][35] in western Pennsylvania, eastern Ohio, and adjacent northernWest Virginia. Tannehill was promoted to captain on July 29, 1779,[36] and by late 1780 commanded the regiment and was commandant of Fort McIntosh.[37][38]
Tannehill was discharged from service on January 1, 1781,[39] when several regiments, including Tannehill's, were disbanded as a result of Congress's major 1781 reorganization of the Continental Army instituted to reduce expenditures and increase organizational efficiency.[40] In a letter to Major General William Smallwood penned on Christmas day of 1780, Tannehill made note of his regiment's formal disbanding and the termination of his own period of service that were to occur seven days later. (Smallwood was Maryland's highest ranking military officer at this time in the war.) Tannehill's objective was to gain Smallwood's personal assistance in securing a position for himself in the Maryland Line because of his "great desire of Continuing in the Service of [his] Country".[41] Tannehill further affirmed that "I shall do every thing [sic] in my power to keep [the men] together till I have some instructions [from you] respecting them".[41] Smallwood could not grant Tannehill's request because of the recent congressional directive. The Maryland and Virginia Rifle Regiment was the longest-serving Continental rifle unit of the war.[42]
Tannehill was admitted as one of the original 80 members of the Society of the Cincinnati in the state of Maryland when this fraternal organization was established in 1783.[43][44]
Relocation to Pittsburgh
After his war service, Tannehill settled in frontier Pittsburgh, as did many other Revolutionary War officers and "their accomplished families".[45] He initially engaged in farming and was a tavern owner[46][47] and vintner.[48] He was also a landowner and a "large buyer"[49] of land lots in early Pittsburgh—land purchased directly from the heirs of William Penn.[50] Tannehill was not a slaveholder, like many prominent men of Pittsburgh.[51] From 1784 until around 1792, Tannehill owned and operated the riverfront Green Tree Tavern and Inn located midblock between Market and Wood Streets in Pittsburgh.[50][52] He resided in the adjacent house until 1787 when he moved to his new Grove Hill estate, which became popular as a local center for political meetings while owned by Tannehill.[53] The property was located on Grant's Hill just northeast of Pittsburgh in what is now the city's Hill District. One of the buildings at Grove Hill, known as "the Bowery", was the site of large annual social gatherings hosted by Tannehill where citizens of Pittsburgh came together each Fourth of July "to hail with joyful hearts the day that gave birth to the liberties and happiness of their country".[53][54] Tannehill lived at Grove Hill until his death in 1820.[55]
Early public career

Tannehill began public service no later than 1794 when the borough of Pittsburgh was established.[56] That year, he was appointed president of the Pittsburgh Fire Company[57] and elected one of three surveyors of Pittsburgh.[58] In March 1790, Tannehill had unsuccessfully solicited a public appointment in the administration of President George Washington by writing to Washington's personal secretary, Tobias Lear, who had visited Pittsburgh and lodged with Tannehill at his inn four years before.[59] In his note, Tannehill mentioned that Washington "has some acquantance [sic] of me, which may probably have some weight", referring to instances of direct interaction the two men had during the American Revolution.[3]
Sometime before 1794, Tannehill was appointed a justice of the peace of Allegheny County,[57] an administrative unit that included Pittsburgh. In October 1800, he was temporarily removed from this office after being convicted of extortion related to an event that occurred five years before in which he was alleged to have charged two shillings more than was allowed by law for two probates.[60] He was issued a reprimand and fined fifty dollars.[61] Tannehill was quickly reinstated to office in January 1801 by Governor Thomas McKean, the former chief justice of Pennsylvania, was refunded his fine,[50][61] and subsequently held several prominent elected and appointed public offices. Tannehill believed the charges against him had marred his reputation and vehemently disclaimed any guilt for the rest of his life. His resentment toward whom he called "two of the most unprincipled scoundrels who ever appeared before a Court of Justice" and what he characterized as their "false swearing and vile slander" was still strong 15 years later when he reflected on the affair in his will.[62]
Tannehill was active in the state militia, serving as a lieutenant colonel in the Westmoreland County militia starting in 1788.[50] On August 3, 1811, Pennsylvania Governor Simon Snyder promoted Tannehill to major general of a Pennsylvania militia division drawn from Allegheny, Armstrong, and Indiana counties.[50]
Later public career

Starting in 1804, Tannehill served as a founding member of the board of directors of the Pittsburgh branch of the Bank of Pennsylvania[63] after leading Pittsburgh citizens in a petition to establish the branch.[54] (This was the first bank established in Pittsburgh and the first one west of the Allegheny Mountains.)[63] He was then appointed by the Pennsylvania state legislature as one of five turnpike commissioners for the state starting in 1811.[64] The commissioners' task was "to view the different routes for…turnpike roads from Harrisburg to Pittsburgh".[64] Tannehill was also chosen by the state legislature as an elector to the 1812 federal Electoral College for the state of Pennsylvania.[65] However, he was unable to attend the elector voting in December that year due to his military activities during the War of 1812.[66]
After the War of 1812 broke out, Tannehill served as a brigadier general commanding four infantry and rifle regiments of United States Volunteers.[67] In his most significant effort of the war, Tannehill and his brigade marched to the American encampment at Buffalo, western New York, in October and November 1812.[68] There, they were to join combined American forces (regular, militia, and volunteer) preparing to establish a foothold on the Canadian side of the Niagara River before the onset of winter. However, they did not arrive in time for the failed invasion, marked by the British victory at the Battle of Queenston Heights in present-day southern Ontario. Tannehill's military duties during the limited duration of the war in western Pennsylvania lasted from September 25 to December 31, 1812.[1]
Meanwhile, outside of public office, Tannehill served as an inaugural trustee of the First Presbyterian Church of Pittsburgh starting in 1787.[69][70] He was also a member of the fraternal Tammany Society, which was founded after the American Revolution in several American cities, including Pittsburgh.[71] The society focused on the celebration of American identity and culture. Members of the society in its earliest years closely allied themselves with the Democratic-Republican party of Thomas Jefferson. Consequently, when Jefferson announced his intent to withdraw from public service in 1808, Tannehill, in his capacity as Grand Sachem (high official) of the Pittsburgh Tammany Society, wrote to "Brother" Jefferson, expressing "heartfelt regret" over his "resolution to retire from the duties of protecting thy children [of this tribe]".[72][73]
U.S. House of Representatives
Although Pittsburgh was a stronghold of the Federalist Party in the city's earliest years, between 1798 and 1800 the rival Democratic-Republican Party began to prosper under such men as Adamson Tannehill, who had become chairman of the city's Republican party by 1800.[74] Tannehill was also a three-time candidate for the U.S. House of Representatives, initially representing Pennsylvania’s 11th congressional district in the election to the 12th United States Congress on October 9, 1810. He was defeated by fellow Democratic-Republican Abner Lacock, who garnered 51.0 percent of the vote; Tannehill earned 43.2 percent, and Democratic-Republican Samuel Smith received a distant 5.7 percent.[75]
The high point of Tannehill's active political career was his election as a Democratic-Republican to the 13th United States Congress on October 13, 1812.[1] Tannehill was elected to serve Pennsylvania's newly established 14th congressional district with 48 percent of the vote, defeating Federalist John Woods and Democratic-Republican John Wilson, who received 39.3 and 12.7 percent of the vote, respectively.[76] Tannehill served from March 4, 1813, to March 3, 1815,[1] casting 322 votes and missing 30.[77]
Tannehill ran for reelection on October 11, 1814, again as a Democratic-Republican, in the 14th United States Congress. He narrowly lost his reelection bid, receiving 49.5 percent of the vote; his opponent, John Woods, whom he had defeated two years earlier, won with 50.5 percent of the vote.[78]
Following his tenure in Congress, Tannehill served as president of the Pittsburgh branch of the Bank of the United States starting in 1817[79] and ending with his death in 1820.
Death
Tannehill died after a short illness at his Grove Hill home just outside Pittsburgh on December 23, 1820, aged 70 years and 7 months.[1][80] He was survived by his wife, Agnes M. Tannehill,[81][82][83][84] and his ward, Sydney Tannehill Mountain.[85] Adamson and Agnes had no children.[86] Tannehill was interred at his Grove Hill home,[87] as specified in his will.[88] His 1820 obituary relates that "his remains were accompanied to the grave by a large concourse of his fellow citizens and were interred with military funeral honors by two…Volunteer Corps" of the Pittsburgh area.[80]
Tannehill's body was reinterred in Allegheny Cemetery in Pittsburgh on April 26, 1849,[89] because urban spread and city road construction necessitated moving his Grove Hill grave. The archive files of a prominent Pittsburgh newspaper provide detail on this reinternment: "after the big fire in 1845, when [the Pittsburgh city] council extended the city limits to take in the farms on what is now the Hill district…it was found that in extending Wylie avenue, Colonel Adamson Tannehill's grave would be between the curbs…About 1851[sic] [the] council decided to remove the colonel's remains to Allegheny cemetery. The Tannehill family objected, but [then] agreed to make the transfer themselves".[90]

Consequently, June 14, 1775, is recognized by the current U.S. Army as its formal date of establishment.

Fort Duquesne was a fort established by the French in 1754, at the confluence of the Allegheny and Monongahela rivers. It was later taken over by the British, and later the Americans, and developed as Pittsburgh in the U.S. state of Pennsylvania. Fort Duquesne was destroyed by the French before its British conquest during the Seven Years' War, known as the French and Indian War on the North American front. The British replaced it, building Fort Pitt between 1759 and 1761. The site of both forts is now occupied by Point State Park, where the outlines of the two forts have been laid in brick.
Fort Prince George was an uncompleted fort on what is now the site of Pittsburgh, at the confluence of the Allegheny and Monongahela Rivers in Allegheny County, Pennsylvania. The plan to occupy the strategic forks was formed by Virginia Lieutenant Governor Robert Dinwiddie, on the advice of Major George Washington, whom Dinwiddie had sent on a mission to warn French commanders they were on English territory in late 1753, and who had made a military assessment and a map of the site. The fort was still under construction when it was discovered by the French, who sent troops to capture it. The French then constructed Fort Duquesne on the site.
Daniel Morgan was an American pioneer, soldier, and politician from Virginia. One of the most respected battlefield tacticians of the American Revolutionary War of 1775–1783, he later commanded troops during the suppression of the Whiskey Rebellion of 1791–1794.
The siege of Boston was the opening phase of the American Revolutionary War. In the siege, American patriot militia led by newly-installed Continental Army commander George Washington prevented the British Army, which was garrisoned in Boston, from moving by land. Both sides faced resource, supply, and personnel challenges during the siege. British resupply and reinforcement was limited to sea access, which was impeded by American vessels. The British ultimately abandoned Boston after eleven months, moving their troops and equipment north, to Nova Scotia.
The 1779 Sullivan Expedition was a United States military campaign during the American Revolutionary War, lasting from June to October 1779, against the four British-allied nations of the Iroquois. The campaign was ordered by George Washington in response to the 1778 Iroquois and British attacks on the Wyoming Valley, German Flatts, and Cherry Valley. The campaign had the aim of "taking the war home to the enemy to break their morale." The Continental Army carried out a scorched-earth campaign in the territory of the Iroquois Confederacy in what is now western and central New York.
John Gibson was a veteran of the French and Indian War, Lord Dunmore's War, the American Revolutionary War, Tecumseh's War, and the War of 1812. A delegate to the first Pennsylvania constitutional convention in 1790, and a merchant, he earned a reputation as a frontier leader and had good relations with many Native American in the region. At age sixty he was appointed the Secretary of the Indiana Territory where he was responsible for organising the territorial government. He served twice as acting governor of the territory, including a one-year period during the War of 1812 in which he mobilized and led the territorial militia to relieve besieged Fort Harrison.
William Crawford was an American military officer and surveyor who worked as a land agent alongside George Washington while Washington was a teenager. Crawford fought in the French and Indian War, Lord Dunmore's War and the American Revolutionary War arising to the rank of Colonel. In 1782, his unit was attacked, and while he and his surgeon escaped for less than one day, Crawford was eventually captured where he was tortured and burned at the stake by Crawford's former soldier turned British agent, Simon Girty, and Captain Pipe, a Chief of the Delaware Nation.
Guyasuta was an important Native American leader of the Seneca people in the second half of the eighteenth century, playing a central role in the diplomacy and warfare of that era. Although he became friends with George Washington in 1753, he sided with the French against Britain during the French and Indian War and fought against the British in Pontiac's War. He later supported the British during the American Revolutionary War. In his final years, he engaged in peacemaking to end the Northwest Indian War.
William Irvine was an Irish-American physician, soldier, and statesman from Carlisle, Pennsylvania. He practiced medicine as a ship's surgeon for the Royal Navy before he sympathized with the American Revolution and fought against the British during the American Revolutionary War. As tensions escalated between the American colonies and the British government during the 1770s, Irvine sympathized and allied himself with the revolutionary cause. He subsequently served as a brigadier general in the American Revolutionary War and served in the western theater. After the war he served in the Continental Congress, and later played an active role in ending the Whiskey Rebellion in Pennsylvania. He also served one term in Congress representing Pennsylvania, and was also active in the state's other public affairs.
The 8th Pennsylvania Regiment or Mackay's Battalion was an American infantry unit that became part of the Continental Army during the American Revolutionary War. Authorized for frontier defense in July 1776, the eight-company unit was originally called Mackay's Battalion after its commander, Colonel Aeneas Mackay. Transferred to the main army in November 1776, the unit was renamed the 8th Pennsylvania Regiment on 1 January 1777. It completed an epic winter march from western Pennsylvania to New Jersey, though Mackay and his second-in-command both died soon afterward. In March 1777 Colonel Daniel Brodhead assumed command. The regiment was engaged at the Battles of Bound Brook, Brandywine, Paoli, and Germantown in 1777. A body of riflemen were detached from the regiment and fought at Saratoga. Assigned to the Western Department in May 1778, the 8th Pennsylvania gained a ninth company before seeing action near Fort Laurens and in the Sullivan Expedition in 1778 and 1779. The regiment consolidated with the 2nd Pennsylvania Regiment in January 1781 and ceased to exist.
The 13th Virginia Regiment was a United States infantry regiment during the American Revolutionary War.
Samuel Ross Mason, also spelled Meason, was a Virginia militia captain, on the American western frontier, during the American Revolutionary War. After the war, he became the leader of the Mason Gang, a criminal gang of river pirates and highwaymen on the lower Ohio River and the Mississippi River in the late 18th and early 19th centuries. He was associated with outlaws around Red Banks, Cave-in-Rock, Stack Island, and the Natchez Trace.
The Maryland and Virginia Rifle Regiment, most commonly known as Rawlings' Regiment in period documents, was organized in June 1776 as a specialized light infantry unit of riflemen in the Continental Army during the American Revolutionary War. The American rifle units complemented the predominant, musket-equipped, line infantry forces of the war with their long-range marksmanship capability and were typically deployed with the line infantry as forward skirmishers and flanking elements. Scouting, escort, and outpost duties were also routine. The rifle units' battle formation was not nearly as structured as that of the line infantry units, which employed short-range massed firing in ordered linear formations. The riflemen could therefore respond with more adaptability to changing battle conditions.
A flying camp was a military formation employed by the Continental Army in the second half of 1776, during the American Revolutionary War.
Otho Holland Williams was a Continental Army officer from Maryland in the American Revolutionary War. He participated in many battles throughout the war in the New York, New Jersey and Southern theaters, eventually ending his career as a brigadier general.
The Battle of Trenton was fought on December 26, 1776, during the American Revolutionary War campaign for New Jersey. In a surprise attack, the Continental Army led by George Washington attacked the winter quarters of a brigade composed primarily of German troops from Hesse-Kassel in Trenton, New Jersey. The Hessian brigade was under the command of Colonel Johann Rall; he died of wounds sustained in the battle, and about two thirds of his men were taken prisoner. It was the first major victory after a long string of defeats that had resulted in the loss of New York City, and was a significant boost to American morale. It was followed by two more American victories, first in a second battle at Trenton on January 2, 1777, and then on January 3 at Princeton.
Moses Rawlings (1745–1809) served in the Continental Army during the American Revolutionary War, most notably at the Battle of Fort Washington. He attained the rank of lieutenant colonel before leaving the military in 1779. He later served as the State Commissioner for Prisoners in Maryland.
Daniel Brodhead was an American military and political leader during the American Revolutionary War and early days of the United States.
John Wilkins Jr. was a United States Army officer who served as Quartermaster General of the United States Army from 1796 to 1802.
