Henry Defendorff enlisted as a sergeant in Christoper P. Yates’s Tryon County company of the 2nd New York Provincial Battalion commanded by Col. Goose Van Schaick, on July 20, 1775. The position of his name on the company muster roll indicates he was the company’s second sergeant. The original company didn’t exist for long; shortly after the surrender of Fort Chambly in October 1775, it was disbanded and rebuilt under 1st Lt. Andrew Finck to finish out the year. Defendorff joined the company officer corps with a promotion to 2nd lieutenant in November.
In February 1776, Finck and his men were absorbed into the new unnumbered Continental battalion commanded by Col. Goose Van Schaick, as the 4th company. Finck was promoted to captain. Defendorff continued as 2nd lieutenant, but was soon promoted to 1st lieutenant in July. He was climbing the ranks quickly, though his service with the battalion in 1776 was spent mostly on furlough in Albany, New York.
During this period there were two events that directly involved Defendorff as an individual. The first occurred in late May 1776, when Capt. Joseph Bloomfield of the 3rd New Jersey Regiment was traveling east on horseback from Johnstown, New York, on regimental business. He was surrounded by about twenty Loyalists some five miles outside of Albany. Bloomfield wrote in his journal that they claimed that Lt. Col. Anthony Walton White, of his regiment, had earlier confiscated the horse and that they:
…were determined to dismount me, upon which I took out my Pistols out of my Pocket & told them I would be the death of two of them at least if they did not let go of the Reins of the Bridle immediately, that I would after discharging my Pistols, make use of my sword & sell my life as dear as possible before they should have the Horse….
…By this time Mr. Defendaff a Lieut. in Col. Van Schaick’s Regt., came up drew his sword & said He wod stand by me to the last, which struck such a Terror in those Cowardly Rascals that they left me to take the Road with my Horse as I pleased….
The second, less dramatic, event happened around July 24, 1776, when Defendorff carried a message to the General Hospital at Fort George informing them that “a large number of sick are coming.” The documentation does not show any written message, who sent him, or why he was selected, though the confirmation of his arrival was sent back to Maj. Gen. Horatio Gates.
Both events clearly demonstrated Defendorff’s true character as a reliable and brave officer, yet somewhere along the way his superiors labeled him as “middling.” So, when the powers-that-be got together in Saratoga, New York, to determine who should be recommended to the New York Provincial Congress Committee of Arrangement for officer’s commissions in 1777, he was passed over.
All was not lost, however, for on December 9, 1776, Jacob Cuyler, a leading member of the Committee of Safety, Correspondence, and Protection in Albany, NY wrote to William Duer, New York Provincial Congressman and a member of the Committee of Arrangement that:
Mr Henry Devandorph, who was given up to us as indifferent, has, since we were at Saratoga, done some very extraordinary services. This I have from Col Van Schaack; and I believe he will make a good officer. He is full of spirit and pride I know, and from what I can learn, he is sorry for the offence he has given some time ago to one of his Field Officers.
The particular offense is unknown, but it appears pretty clear who the offended officer was. In view of the fact that the 2nd New York in 1775 and Van Schaick’s (unnumbered) New York battalion in 1776 had the same field officers, it had to have been Col. Goose Van Schaick, Lt. Col. Peter Yates, or Maj. Peter Gansevoort. Of the three, only Colonel Yates, appears to have been the type of officer to report even a minor offense to his immediate superior. This was borne out back in 1775 when Yates had Capt. Joel Pratt of the 2nd New York arrested and court-martialed, at Fort Ticonderoga, over their exchange of words regarding Pratt’s not filling out a troop return correctly.
Lucky for Defendorff, Colonel Van Schaick would go even further than he had earlier in the month and write to the Committee of Arrangement late in December. There he took “…the liberty to recommend to the notice of the Committee, in the room of those who declined for lieutenants…,” several gentlemen he felt worthy. One of them was Henry Defendorff.
As a result, right after the third establishment of the Continental Army was formed in late 1776; Henry Defendorff was commissioned 1st lieutenant of the 1st company of Col. Goose Van Schaick’s 1st New York Regiment, but was soon inexplicably transferred to Col. Peter Gansevoort’s 3rd New York’s 1st company instead.
Defendorff would be with the 3rd New York regiment during the siege of Fort Schuyler in August of 1777. In fact, with the enemy closing in, he was to take a key part. According to the journal reportedly penned by Ensign William Colbreath of the 3rd New York, on August 6, 1777:
This morning the Indians were seen going off from around the garrison towards the landing; as they withdrew we had not much firing. Being uneasy lest the Tories should report that the enemy had taken the fort, Lieut. Diefendorf was ordered to get ready to set off for Albany this evening to inform General Schuyler of our situation, but between nine and ten this morning three militia men arrived here with a letter from General Harkeman [Herkimer] wherein he writes that he had arrived at Orisco [Oriskany] with 1,000 militia, in order to relieve the garrison and open communication, which was then entirely blocked up, and that if the colonel should hear a firing of small arms, desired he would send a party from the garrison to reinforce him. General Harkeman desired that the colonel would fire three cannon, if the three men got safe into the fort with his letter, which was done and followed three cheers by the whole garrison.
A relief column under the command of Lt. Col. Marinus Willett, including Defendorff’s “thirty as flank guards” under the command of other officers, was quickly sent out. Covering just a half-mile, it came upon an enemy encampment which they routed and plundered. After taking a number of casualties, the column did not proceed, but returned to the fort with their booty. Herkimer’s militia column was ambushed at Oriskany that very day, where they stopped the enemy, but took very heavy losses.
Defendorff presumably remained at Fort Schuyler until he signed a testimonial letter from the officers of the 3rd New York to their commander, Col. Peter Gansevoort, on October 12, 1777. He was subsequently listed on the rolls as being on recruiting duties through early April 1778, despite having resigned on November 1, 1777, by leave of Colonel Gansevoort. Why he remained on duty those extra months is not explained. Defendorff is known to have returned to Fort Schuyler, as he co-signed his company’s muster roll that was filled out there in April 1778. He was finally omitted from the rolls in May 1778.
One answer to this question might be found in the record of John Ball, former 1st Lieutenant of the regiment’s 5th company, who was veteran of Willett’s sortie out of Fort Schuyler. Similar to Defendorff, he “went to resign by leave of Col. Gansevoort” on December 29, 1777. Unlike Defendorff, he filed an application for a Federal pension, which explains that “…there was an arrangement by order of Congress to reduce the number officers and it was the misfortune of Lieut Ball (he being the oldest Lieut in the Regiment) to have his further services dispense with.”
As part of a sweeping resolution, dated November 24, 1778, the Continental Congress reinforced that:
Whereas from alteration of the establishment and other causes, many valuable officers have [been] and may be omitted in the new arrangement as being supernumerary, who, from their conduct and services are entitled to the honorable notice of Congress…and that all supernumerary officers be entitled to one year’s pay of their commissions respectively….
Attrition was far greater among the Continental Army’s enlisted men, necessitating a way to force the excess officers to retire. (The New York regiments would go through a further downsizing in October 1780 when they reduced from five down to two Continental regiments.) They became known as “retired supernumerary officers,” even though, at least in the 3rd New York, they were listed as resigning. Such inaccuracies could lead to administrative trouble for officers like John Ball when filing for pension, even though during the war, they seemed to know the situation. Defendorff, for example, would later be described as “retired as Supernumery,” so he clearly did not voluntarily resign, but was, in fact, retired.
To this point, Henry Defendorff had spent much of his time in the Continental Army on individual service. While with Van Schaick’s Battalion in 1776, he was on furlough in Albany for as much as eleven months. During this period he had performed some unspecified “very extraordinary services,” delivered a message to the Fort George Hospital, and had come to the aide of Capt. Joseph Bloomfield. With the personal assistance of the Colonel Van Schaick, Defendorff received a high-placed 1st lieutenant’s commission in the new arrangement for 1777, but was suddenly transferred to another regiment. While with that new regiment, he was selected to carry an important message personally to Major General Schuyler. Why him? Clearly, there is more to Defendorff’s story than meets the eye.
The only portion of that story that appears customary is that when Defendorff was off recruiting, there were six other company officers in the regiment doing the same thing. On the other hand, with his previous service in mind, one would question if he was really recruiting. Unfortunately, lacking any supporting documentation or a pension deposition there is not much that can be proved one way or the other.
After his retirement from the 3rd New York, Deffendorf appears as a householder in Middletown Township, New Jersey, in December 1778, March 1779, and in 1780. This township is on the New Jersey shore at Sandy Hook Bay, just below Staten Island. His wife, Hannah, and son were living with him. There appears to be no record of his son’s age. At one point in late 1780 or early January 1781, while he and the family were up in Newark, New Jersey, they were taken prisoner, for no documentable reason, by the British and transported to New York City.
Given the choice of imprisonment or enlisting in a Loyalist regiment, Defendorff enlisted on January 25, 1781, as a cavalryman in Capt. Gilbert Livingston’s Troop of Benedict Arnold’s American Legion. One Jacob Defendorff, who was probably his son, enlisted in the same troop four days later. Jacob, who had been sick on Long Island, disappears from the rolls as of May 1. Henry disappears from the rolls as of January 15, 1782.
Meanwhile, on November 8, 1782, Maj. Gen. William Heath reported from Continental Village (located just north of New York City, near Peekskill) to New York Governor George Clinton at Poughkeepsie that:
I forward, one Henry Defendorff, who left New York the night before last with three others, and arrived Wed here the last evening. Defendorff is a very intelligent man, says he was a lieutenant in the Third New York Regiment, retired as Supernumery, was taken at Newark and with his wife and Child carried to New York, where he inlisted into Arnold’s Corps with a view to get his Liberty the first opportunity that offered,— his wife and child are down at Niack with the water Guard. Your Excellency who probably knows his Character will best know how he is to be treated. Defendorff has been employed in a way, that has given him an opportunity of knowing the situation of the Enemy as well as any man I have seen, and can give you many particulars.
The night before, General Heath had written in his own journal about how the two deserters who had arrived at Continental Village (which were logically the common deserters Henry and Jacob Defendorff), had made their escape:
Two deserters came in from New York; they left the city the evening before—they were very intelligent; by them it was learnt that the British fleet returned to Sandy Hook the preceding Saturday was a week—that no action happened while they were at sea—that the troops were disembarked from the men-of-war, but remained on board the transports—that Gen. Sir Henry Clinton landed on Long Island and came across to the city.
The phrase “very intelligent man” indicated the man was in possession of valuable military intelligence. Since Defendorff had made his newest home in the New Jersey town next to Sandy Hook and served with the British, he would be able to provide a lot of information. It also bodes the question, had Defendorff moved way down there for other reasons than personal preference? Perhaps he was watching the British fleet? Also, what was he doing in Newark that got him arrested?
Nevertheless, there was sufficient information provided to prompt Governor Clinton to send a letter back to General Heath on November 10, 1781, that he had consigned Defendorff to the Committee of Conspiracies and presumed they would permit him “to take his Family to Schenectady where his Relations reside & his political Character can be better ascertained than at this place.”
If Defendorff’s family (his own or his in-laws) was from Schenectady, New York, this could explain why he was there to confront Captain Bloomfield’s attackers outside of Albany. Yates’s company of the 2nd New York of 1775 was geographically recruited from Tryon County, but Schenectady was relatively close to the county line. It is also only about fifteen miles west of Albany. So, he could have been in transit between locations when Bloomfield was confronted. Then again, being familiar with the area, he could have been there for other reasons.
There is no known record of what service Henry Defendorff provided after being handed over to the Committee of Conspiracies. He was awarded New York State bounty land of two 600-acre lots in Onondaga County, New York, on July 9, 1790. As a resident of Dover, Delaware, he arranged to transfer what might have been the awarded two lots of land, to two individuals, in 1793. He also tried to transfer the land to a third party, claiming he had not previously sold the land.
It is very frustrating to come to the end of this narrative and have no definitive conclusion. The facts presented show Henry Defendorff to be a sound and reliable officer who served with distinction. Any other conclusions that might be drawn from this narrative are purely speculative. They do give one pause to think of the intriguing possibility that, for much of the war, Henry Deffendorf may have been involved with intelligence-gathering, conveying information, or other forms of espionage.

The roll lists him as a 1st lieutenant and joining the battalion on February 16. It also states he was on furlough in Albany. The dates of this furlough are not given, so it could have been for all eleven months. It also does not list his promotion from 2nd lieutenant, so the muster roll had to have been rewritten after July 1776 or he actually started out with the battalion as 1st lieutenant in February.
