William Clark and the Raritan Bay Horse Thieves
by Michael Adelberg

- May 1781 -
There is little known about William Clark’s early life. While an antiquarian source claims he was from Dover Township, his father (Dr. William Clark) was a physician in Middletown Township. So, William Clark (Jr.) likely grew up in Middletown. Perhaps he lived in Dover Township before the war—but he is not listed as owning land in the 1773 tax list for that township. His wife and children were in Middletown by the middle years of the war.
The Clarks of Middletown were disaffected from the Revolution (another Clark family from Freehold Township solidly supported the Revolution). Dr. Clark was accused of illegally trading with the British in early 1777 and jailed in Freehold until November when he petitioned for his release. Dr. Clark’s 1779 estate was only 13 acres and one head of livestock—a very modest estate. Dr. Clark was likely a physician to prominent disaffected families along the Raritan Bayshore, such as Kearney’s of Keyport and Amboy. As their fortunes dropped, so did Dr. Clark’s.
William Clark (Jr.) was also disaffected. His wife, Mary Tilton, was from a disaffected family that included Clayton Tilton, an active Loyalist raider, and other Loyalists. William Clark was arrested for high treason in January 1778 and convicted at the 2nd Court of Oyer and Terminer in June. But in an act of mercy afforded to a young man from a “good” family, he was permitted to sign a pledge of good behavior, post a bond, and was released.
The Raritan Bay Horse Thieves
The earliest documentation of robberies committed by Clark is a January 1782, New Jersey Supreme Court record that discusses a robbery committed by four Clark family members in January 1780. Elizabeth Pritchard was robbed of £29 of household goods and livestock by a gang consisting Nicholas Clark, Robert Clark, Andrew Clark, and James Clark. Two years later, the gang was convicted of trespass and breaking & entering "for taking away and conveying her goods & chattels to very great damage."
The Raritan Bay Horse Thieves are discussed in a June 1780 report printed in a New York newspaper. The New York Packet reported:
On the 19th instant, three spies and horse thieves were hanged at Headquarters near Morristown; they were taken in Monmouth County by some of our militia. The gang consisted of five, one was killed, and another made his escape. They were harbored by a Quaker, who is now in custody, and it is expected that he will in a few days receive the reward his conduct deserves.
The prisoners were William Hutchinson, John Clawson, and Lewis Lacey. Lacey was from a modest Middletown family. Hutchinson and Lacey were from families that included other Loyalists.
Horse thieves were particularly detested in agrarian America because horses were essential to working the farm and transporting people. The New Jersey Legislature specifically enumerated horse theft as a capital offense; the theft of other animals was not. Unlike other Loyalist raiders, such as the Black Brigade, the Raritan Bay horse thieves were not linked to “man-stealing” or arson—though stealing horses was a capital crime in its own right.
By this time, William Clark was associated with these and other Loyalist irregulars based on Sandy Hook. Clark’s growing infamy prompted Middletown’s magistrate, Peter Schenck, to move against Mary (still residing in Middletown) in May 1781. Schenck wrote Governor William Livingston:
I beg leave to request a favor of your Excellency - A certain Mary Clark, with two children, resides in sd township, her husband, William Clark, is on Staten Island. Said woman and children are very good [but] have no means of support to subsist on. She makes an application to the town for support. She may be willing to go to her husband, provided your Excellency permits her passing there; sd Township being overburdened with poor, seek her passage from sd Township over to Staten Island, with her children and what small matter of effects she might have.
Schenck noted that people in Middletown wanted to remove Mary Clark for their own safety:
We would not trouble your Excellency with sd request did we not conceive it would save the town from great cost and also may be a means of preventing sd [William] Clark, in a great measure, from coming amongst us, as he is a great villain - and has kept many in fear of being taken off by him, amongst which I include myself.
While Mary Clark followed a trickle of Loyalist women from Monmouth County into British lines, Dr. Clark, William’s father, remained in Middletown. Deprived of family, he apparently suffered on his undersized estate. In September, the Loyalist New York Gazette reported that Dr. William Clark had died "from rebel cruelty." The specifics of Dr. Clark’s demise are not stated.
On June 21, 1781, a massive raiding party of at least 1,000 men marched through Middletown. As the local militia left their posts to resist the incursion, horse thieves on Staten Island took advantage. Asher Holmes, commanding the Middletown militia, reported on June 22 that the prior day: "a party of refugees from Staten Island in boats landed at Shoal Harbor and took eight or ten horses" while the militia was diverted.
In July 1781, Silas Condit of the New Jersey Legislature wrote Governor Livingston:
We have direct information from N. York and Staten Island, the trade of horse stealing flourishes amazingly, and I think it advisable and for the good of the State to offer a pretty handsome reward for apprehending Caleb Sweezey, Isaac Sweezey, Nathan Horton, junior, James O'Hara, John Moody and there is one Giberson from Monmouth whose Christian name I am not certain of... a number may be carrying on this business with too great success, and I think we ought to give encouragement to such as may take pains to apprehend them, for without it, they are not likely to be taken.
Livingston acted on August 8 when he placed bounties on the head’s of four dangerous robbers. On August 15, the New Jersey Journal advertised Livingston’s bounties: $200 on the heads of Caleb Sweezey, O'Hara, Moody, and Guisebert Giberson for their "atrocious offenses, diverse robberies, thefts and other felonies." A bounty was not put on Clark’s head. Perhaps this was because Clark was not tied to a specific violent act or because of the higher social status of his family. But his father was “suffering” in Middletown at this time—probably from extra-legal retaliation.
The precise crimes of the men with bounties are not listed in surviving documents, but, for some, it may have been a combination of robberies committed along the Atlantic shore (as part of Pine Robert gangs) and activity as a Raritan Bay horse thief. It is easy to imagine that a Pine Robber, while delivering taken goods to Sandy Hook and Staten Island, joining a group of thieves forming to raid Middletown and taking horses. Clark’s Dover Township ties make this that much more likely.
The bounties coincided with quick actions against three Loyalists:
Caleb Sweezey was promptly caught and convicted of counterfeiting, but escaped from the Monmouth County jail on September 4. He was indicted for murder in 1782 but never caught.
James O’Hara was killed by a posse on August 8 (the same day that Livingston signed the bounty order).
John Moody was the brother of the famous Loyalist partisan, James Moody. He was caught and jailed; he was hanged November 21.
Interestingly, the bounty on Guisebert Giberson was a mistake. On October 9, the bounty on his head was rescinded and placed on the head of his nephew, the Pine Robber leader, William Giberson.
Other horse thieves penetrated deep into Monmouth County. On November 2, Major Elisha Walton (a leading Retaliator and the antagonist to disaffected residents in the landmark Holmes v Walton litigation) was robbed of a horse, taken from his farm near Freehold. He offered a £3 reward for the return of the horse and an £10 reward "for the horse & thief." The thieves were likely John Thomson and Joshua Pierce. The New Jersey Gazette reported on December 19:
John Thomson and Joshua Pierce were convicted of horse stealing and robbery, Richard Bell of Robbery, and were all sentenced to be hanged on Saturday last, -- We hear that Thomson and Pierce were executed accordingly, but that Bell was respited for a few days.
Prior to their hanging, Chief Justice David Brearley (of Upper Freehold) recommended a pardon for Pierce “on account of his youth.” But the recommendation was apparently not acted upon.
The Raritan Bay horse thieves likely participated in two February 1782 raids into northern Monmouth County—one against Pleasant Valley and the other against Colts Neck. The first of these raids resulted in the capture of several men, nineteen horses and five sleighs of plunder. The second raid featured, according to the New Jersey Gazette, “sundry sorties upon the sheep and the calves, making great numbers of them prisoner.” It is unknown if Clark, himself, participated in either raid.
As is so often the case with outlaws, William Clark was finally caught. On July 3, 1782, the New York Gazette, printed a June 20 letter:
William Clarke, the noted horse thief, is no more. He was shot somewhere in the vicinity of Woodbridge on one of his customary excursions. This man was an early refugee from Jersey, and has since the Fall of 1776 taken off upwards of one hundred valuable horses from the County of Monmouth, and other counties, for which he found ready sale on Long Island and New York. He had eluded the strictest vigilance of our guards and scouts for upwards of five years, although it is pretty certain he passed at least half that time within our lines.
According to the letter, Clark was lured into an ambush by a "friend" who informed him that two horses were available for easy taking, while a militia party laid in wait. Clark was killed with an associate "one Miers, of the same profession." An antiquarian source claims that Clark led at least a dozen raids from Sandy Hook and Staten Island and "stole upwards of one hundred valuable horses which he sold to the Royal Army." Another antiquarian source discussed the “Raritan Cowboys” (a gang of Loyalist horse thieves) without specifically naming Clark.
Perspective
Surviving documents do not well detail the Staten Island-based Loyalists who raided Monmouth and Middlesex Counties for horses. A direct connection between these men and other Loyalist irregulars—including the Pine Robber gangs of the Jersey shore—is undocumented. While Clark focused on the Raritan Bayshore of Monmouth and Middlesex counties while the Pine Robber gangs of 1781-1782 laired fifty miles south, they may have had links. William Clark had contacts in Dover Townships (a center of Pine Robber activity) and the August 1781 bounties put out by Governor Livingston include men who were probably associated with both Raritan Bay horse thieves and the Pine Robbers.
Only a handful of the specific horse robberies of the Raritan Bay horse thieves are documented. The sad reality is that there was so much violence and kidnapping in Monmouth County in 1781 and 1782 that the robbery of a horse, of itself, was not newsworthy. As such, the activities of Clark and his associates weew vastly under-reported. While the claim that Clark was involved in the theft of “upwards of one hundred” horses is likely exaggerated, it is probable that he was involved in the theft of at least few dozen or more. This would have made Clark and his colleagues a very real threat to the people of northern Monmouth County and coastal Middlesex County.
