In September 1778, Lt. Helmer and eight
scouts under his command were sent to the
Unadilla River Valley to spy on Joseph Brant's company of Indians and Tories who were encamped at
Unadilla near the confluence of the Unadilla and
Susquehanna Rivers. It was feared that Brant would send a
raiding party north to the Mohawk Valley during the
harvest season to forcefully obtain stores for the winter ahead. When Helmer's scouts reached Edmeston Manor, the farm of
Percifer Carr, just north of what is now
South Edmeston, they were attacked by a large group of Brant's men, apparently part of the feared raiding party on its way north. Several of the scouts were killed, but Helmer managed to escape. Helmer took off running to the north-east, through the hills, toward
Schuyler Lake and then north to
Andrustown (near present-day
Jordanville, New York) where he warned his sister's family of the impending raid and obtained fresh
footwear. He also warned
settlers at
Columbia and Petrie's Corners, most of whom then fled to safety at
Fort Dayton. When Helmer arrived at the fort, severely torn up from his run, he told Colonel
Peter Bellinger, the commander of the fort, that he had counted at least 200 of the attackers en route to the valley. (see
Attack on German Flatts (1778)). The straight-line distance from Carr's farm to Fort Dayton is about thirty miles, and Helmer's winding and hilly route was far from straight. It was said that Helmer then slept for 36 hours straight. During his sleep, on September 17, 1778, the farms of the area were destroyed by Brant's raid. The total loss of property in the raid was reported as: 63
houses, 59
barns, full of
grain, 3
grist mills, 235
horses, 229 horned
cattle, 279
sheep, and 93
oxen. Only two men were reported killed in the attack, one by refusing to leave his home when warned. Three days later Helmer led another group of militia back to the Carr farm on the Unadilla, discovered the bodies of three of his scouts, and buried them at that site. The fate of the other five scouts is not known. Helmer also served in the New York State Levies under Colonel
Lewis DuBois. ==Personal==
