On the western front of the Revolutionary war the British and Indians carried out a campaign of annihilation against the farms and settlements in New York and Pennsylvania. Under instructions from Congress, George Washington sent General Sullivan to destroy the Indian economy and throw them wholly on the British for support.


Few people are aware that the farthest west Revolutionary Battle in New York State was here in Livingston County.


The Groveland Ambuscade resulted in the death of Indian guide Han Yost and the loss of 16 of General Sullivanís men at Groveland and the torture death of Lt. Thomas Boyd and Michael Parker at Little Beardís Town (near Cuylerville).


How did that save lives you may ask?


Consider the situation.  Major-General John Sullivan and General Clinton had encamped their army of near 3000 on the high ground east of Conesus Lake while their engineers prepared a road across the swamp and a bridge across the inlet. ( While a man on foot could use the Indian paths a pack horse would break through and an army would turn it into a quagmire ).


The location of British Colonel Butler and Indian Chief Brant with their under 1000 men was not known. Neither was the exact location of their headquarters at the Indian town of Chinese Castle or Little Beardís Town.


Meanwhile  Butler and Brant had set up an ambush in the ravines and forests near the top of the slope west of Conesus Lake. They would have the superior position and element of surprise. The ambush location was over three miles from the armyís encampment and about 1/2 mile from the construction site. If the battle became too intense they would have easy retreat to the Genesee valley. From here they watched the armyís activities.


The lay of the land and the armyís habit of following the Indian trails predicted the probable path Sullivan and Clinton would follow.


Unlike the Newtown battle, Sullivan no longer had his heavy cannon and would not be set up in a standard battlefield array because of the swamp and narrow roadway and bridge.


The night of Sept 12, 1779, General Sullivan ordered Lt.Thomas Boyd to lead a party of 3 or 4 to find Little Beards Town the Seneca Castle. The party grew to about 25 mainly Morgans riflemen.


The scouts passed the enemy lines undetected. Neither  side was aware of the otherís presence.


The scouts arrived before dawn at the deserted   Gathtsegwarohare village. In the morning they encountered several Indians, killing one, and rested there part of the morning. Boyd then sent two runners who reported to General Sullivan that the scouts were returning.


Lt. Boyd later sent two more runners to report that the scouts would wait on the trail for the army. These men soon returned reporting they had seen Indians on the trail. The scouts started in pursuit of the Indians who were seen from time to time. Their guide HanYost warned it was a trap but the scouts continued the pursuit.


Now on September 13, 1779, comes Boydís returning scouting party approaching Butler and Brant from the rear.  Were they a lone party or were there others?  If they got back to Sullivan, the ambush might be revealed. The scouts were decoyed by the Indians right into the ambush.


A fierce deadly battle ensued inflicting over twice the  patriot casualties that had occurred at the better known battle of Newtown.  Boyd and Parker were captured and taken to Little Beardís Town where their mutilated remains were found the next day. Eight of the scouting party, including Timothy Murphy, escaped the ambush and reported to Sullivan who had become concerned over their delay. Gen. Handís light brigade responded but it was too late.


Butler and Brant, their battle plan exposed, retreated and  the  potential of a major battle was averted Ė probably saving many lives on both sides. Some say saving the army a capital blow.


The army continued on its mission virtually unopposed.


An Historical Note:  Boyd and Parkerís remains were discovered by Paul Sanborn. Moses Van Campen also a member of Morgans Riflemen was in charge of their burial. Both men later settled in western NY.  Van Campenís final resting place is in Until The Day Dawn Cemetery, Angelica, NY. Paul Sanborn settled near Conesus and often brought visitors to the ambuscade site telling its tale. Sanbornís final resting place is in Union Cemetery, on Rt. 256, 2.1 miles north of Scottsburg (location #10 on the tour map).

The Men in Sullivans Army were so greatly impressed by the 22 inch long ears of corn, the fine vegetable gardens and the fruit orchards that many determined to return and settle on this land after the war,


Three such men are:

  • Pvt. John Salmon (1760-1837) was in Groveland with the Sullivan Army.  He was a Morgan Rifleman under Capt. Michael Simpson, same as Lt. Boyd and much of the scouting party.  Although he wasnít in the scouting party, he helped bury Lt. Boyd and Parker at the Torture Tree.  He came back with his family and settled within a mile from the Ambuscade.  Salmon often proudly gave tours of his fallen comradeís graves.
  • Pvt. John Wright (1763-1847) was here with the Sullivan Army.  He was in the 1st Company of the 4th New York Regiment under Lt. Capt. Frederick Weisenfels.  He settled in Groveland within two miles of the Ambuscade at the Sutton-Cottonwood Point area of Conesus Lake.
  • Pvt. Albert Acker (1757-1832) was here with Sullivanís Army  He was in the 9th Company of the New York 3rd  Regiment under Capt. Henry Tiebout. He settled in Groveland in the Sutton-Cottonwood Point area of Conesus Lake.

These three soldiers are buried in the Lakeview Cemetery above the Ambuscade Park.  There may be more soldiers who returned here to settle but we donít have the information to prove it.


In 2006, new research led us to the fact that Hanyerry was not the Oneida Indian Guide killed at the Ambuscade in 1779. It was his brother, Lt. Han Yost.  Hanyerry died in 1795 according to his family histories.


We have newly attached a plaque to the monument, ďOneida Indian Lt. Han Yost, Thaosagwat, was killed at this site on Sept. 13, 1779 while acting as a guide for Lt. Boydís Scouting Party. His brotherís name Hanyerry was mistakenly placed on the monumentĒ.


TOUR GUIDE  USING THIS  MAP (on file at Town Clerkís office)

Start at the park in the Village of Conesus on NY Route 15,  0.7 mi. north of the intersection with County Road 33 (Sliker Hill Road). The log house which is staffed seasonally by the GA-NE-A-SOS  History Keepers has local history displays.


Proceed north on NY 15,  to Footes Corners.  A Stone Monument is in the intersection with Footes Corners Road on your left and a State Historical Marker is on your right. The monument has a bronze relief map of the entire Sullivan Campaign.  Sullivanís army was encamped in this area.


Turn left onto Footes Corners Road to Clark Road.  Turn left onto Clark Rd. Proceed to stop sign and continue straight onto Henderson Hill Road (all season gravel)  to East Lake Road (County Road 8). At the foot of the hill Turn left onto East Lake Road to Sliker Hill Road (County Road 33).


Turn right on Sliker Hill Road across the swamp lands to the bridge near the intersection with NY Rt. 256 -  3.4 miles from the army camp.


Early settlers reported the log remains of the army bridge near this site. From the area of the bridge, you can see the formidable barrier the west side of the valley presented with a steep climb of over 200 feet to where Butler and Brant planned the ambush.


Turn right on NY Route 256.  David Gray Hill Road goes up the hill on the left. (This is a seasonal limited use steep gravel road. David Gray Road leads directly to the entrance of the Ambuscade Park but it is not recommended for general use.) Sullivansí scouts may have used this route. Continue north on NY Rt. 256 and turn left onto Maple Beach Road. Follow Maple Beach Road to Barber Hill Road. Turn left onto Barber Hill Road  to Gray Road. Turn left onto Gray Road  to the Ambuscade Park on your right.  Signs point to the monument beyond the park picnic grounds.


To follow the army route to the site of the Indian village of Gethtsegwarohare from the Ambuscade Park, take David Gray Road left  up the hill past the Lakeview Cemetery to Gray Corners. Continue straight on Rosebrugh Road to Groveland Hill Road (County Rd 2).


Turn right on Groveland Hill Rd  to Adamson Rd. Turn left onto Adamson Rd .  Crossing Logan Road stay straight on (all season gravel) Adamson Rd. to NY Route 63.


The Indian village of Gethtsegwarohare where the scouting party waited was in the valley shortly north and west of the present Adamson Road intersection Farm workers on the lands from here north along Rt. 63 have found numerous arrowpoints and other stone relics that indicate the area was occupied by Native Americans for a very long period.


There are no roads in the middle of the valley along the most probable military route.


Proceed north on Rt. 63  the intersection with NY Route 408. Turn left on Rt. 408 and cross the valley to the intersection with NY Route 36 in Mt. Morris  2.3 mi.

(In 1779, the valley had grass as tall as a man on a horse.).


To continue your tour turn right at the traffic light onto NY Rt. 36 north. You will cross the Genessee River as you leave Mt. Morris just a short distance from where the army crossed on foot in1779.


In the Village of Leicester (pronounced ďLesterĒ) turn right onto NY Rts. 20A & 39. On 20A & 39, just beyond Cuylerville the Boyd and Parker Roadside Shrine & Park is on your right in the area where Little Beards Town stood with itís vast fields of corn, vegetables and fruit orchards. The Seneca had planted as much as they could to support the war.


Although the Iroquois Confederacy was technically neutral during the Revolution, various groups sided with the British or with the Colonists. The Seneca here at Little Beards Town were the Keepers of the Western Door for the Iroquois Confederacy. This was also the headquarters from which British Colonel Butler and Indian Chief Brant carried out their campaigns against the white settlers.


If you are interested in a portion of a book from a from an author who wrote about this, some of the details may be somewhat exaggerated according to our Historian, but nonetheless, still interesting. (click here)
