Peter McNelly – Affidavit




On June 7, 1794, Peter McNelly recounted to George Turner how he escaped from White River Station, a stockade outside of Vincennes (modern-day Indiana). Although he was able to make his way back to Vincennes, his wife remained in their captors’ clutches. McNelly thus asked Turner to apprehend the band of settlers that had seized him and his wife, Queen, in an attempt to sell them back into slavery. The mastermind behind the kidnapping was Henry Vanderburgh, a Vincennes fur trader and militia officer. George Turner, a congressionally-appointed judge for the Northwest Territory, had stopped in Vincennes while riding the circuit. The three principal players in this story shared one common characteristic. McNelly, Turner, and Vanderburgh had all fought in the War of Independence for the Patriots. In response to McNelly’s complaint, Turner worked with his colleague, John Cleves Symmes, to prosecute Vanderburgh for violating the Northwest Ordinance’s prohibition of slavery.

In 1787, the Confederation Congress in New York unanimously enacted the Northwest Ordinance. This piece of legislation established the path to statehood for prospective settlers looking to purchase land from the federal government in the Ohio Valley and Great Lakes regions. The most controversial of the Northwest Ordinance’s provisions was the sixth and final article. While Article VI prohibited slavery in the newly established Northwest Territory, it also upheld the right to recapture “any person escaping into the same, from whom labor or service is lawfully claimed in any one of the original States.”

Conditions on the ground posed an immediate challenge. The Northwest Territory had once been a part of New France, where the French Crown had legalized racial chattel slavery. Settlements like Vincennes functioned as nodes in the vast commercial networks linking France’s continental possessions to its Caribbean colonies through the flow of sugar, furs, grain, alcohol, firearms, and slaves. For these reasons, by the time that Governor Arthur St. Clair and his fellow administrators arrived, slavery had long since taken root within their jurisdiction. During the early 1790s, St. Clair’s administration struggled to assert control over the Northwest Territory as the British remained in forts along the Great Lakes and the Miami Confederacy resisted encroachment by Anglo-American settlers in the Ohio Valley. Thus, when the McNellys left Kentucky in 1793, escaping north meant navigating a war-torn landscape. 

Litigation in the wake of the McNellys’ kidnapping added to the St. Clair Administration’s woes by broaching the subject of the Somerset Decision. Turner made a case to St. Clair that the McNellys were “free by the Constitution of the Territory.” As no statute protected slavery in the Northwest Territory, did residence on free soil spell freedom for the McNellys? In 1795, Symmes took over the case from Turner and negotiated a compromise with the people of Vincennes. McNelly would indenture himself to Vanderburgh for five years in exchange for the latter traveling to Kentucky to obtain manumission papers. In 1833, thanks to support from his fellow Vincennes residents, McNelly successfully applied for a pension from Congress for his service in the Virginia Militia. Evidence remains unclear whether he and Queen ever saw each other again. 

The McNellys’ kidnapping and subsequent ligation revealed conflicts unfolding simultaneously within the territorial administration and on the ground over the legality of slavery in the Northwest Territory. These conflicts in turn can help contemporary historians recognize divisions within the Founding generation over what kind of a republic Congress should build on in the Old Northwest, slave or free. By taking his kidnappers to court, Peter McNelly forced two territorial judges to grapple with how to interpret the Northwest Ordinance in a way that would make Congress’ ban on slavery an enforceable one.

Questions to consider:

  • What did Peter McNelly’s ability to bring suit in a territorial court in 1794 and apply for a pension in 1833 in a state court suggest about the status of free African Americans in the early republic?
  • In many ways, the Peter McNelly’s story spoke to a broader constitutional debate in national politics during the Antebellum era regarding Congress’ power to prohibit slavery in federal territories. Could Antebellum Americans coexist in the “House Divided” with slavery legal in some parts of the Union and illegal in others?

that the last named three persons forcibly seized on this deponent, bound his arms to his side with a rope, and made the rope fast to the tail of Baird’s horse, and thus dragged him this deponent forward into the woods – telling him, exultingly and sneeringly, that he must now go before the Judge – that, at this time, the said Dutton was dispatched back to Vincennes with the said cart and horse, and this deponent disengaged from the horse’ tail, but his arms remained bound – that the said Baird now amounted the last mentioned horse, and after an absence of an hour, or thereabouts, returned on foot accompanied by a person named Henri Renbeau, an inhabitant of Vincennes, leading Baird’ horse and on which was mounted this deponent’s wife, who [???] (as he has been told and verily believes) had been forcibly seized [???] in the dwelling house of the said Vanderburgh – And this deponent for the said that Jean Baptiste Constant, junior, of Vincennes [???], yeoman, and also an Indian, to whose name he is a stranger, accompanied the said Baird to the spot where the first party had halted – that the said Indian, Constant, and Renbeau and Baird acted as a guard over the person of this deponent and his wife, on the route to White River, which they took, and where they arrived the same day at a point about twelve miles, or more from the town of Vincennes;

and that the said Baird brought with him a pair of Handcuffs, with  which he manacled this deponent, and that, in this situation, the deponent remained until near midnight on the sixth day of this instant June, which disengaging one of his hands from the manacles, he made his escape from the fortified station aforesaid, through the roof of the said Moses Decker’s house, and the next morning presented himself before the subscribing Judge, at Vincennes And this deponent furth saith not
