This is doubtless the true story of his death. The Nathaniel Underhill who so slew this one-armed patriot of two wars was a notorious Tory who lived on the southern' part of the Manor in the vicinity of Yonkers. It is said that Sergeant Mart ling had once caused his arrest, hence personal animosity sharpened his cruel hate. After Independence was achieved he found it ' convenient to retire to Nova Scotia, with other Tory refugees, and died there.

Capt. John Romer in his later years gave the following account of the affair : "On the 26th day of May, 1779, a party of Refugees (Tories) suddenly came upon Tarrytown. The inhabitants drove their cattle in great alarm into the woods north of Pocautieo Brook, on the first approach of the enemy. In consequence of their numbers, Capt. Buchanan, (of the Water Guards.) had found it necessary to retreat across the Pocantico, where he lay in ambush awaiting their advance, but they did not go so far. At Tarrytown they killed Isaac Martling or rather Nathaniel Underhill killed him. They then pushed for the house of James Requa, where a guard was kept during most of the war, which they surprised, but the whole party made their escape except one, who was killed, and whose name was John Van Tassel." It will be noticed that this is a very different account of the affair from that given in Bolton's History, and then he locates it at Capt. Glode Requa's, while Capt. John Romer says that the attack was made at that time upon the house of James Requa, which was on the Bedford road. And then Capt. Romer gives a different version and place of the killing of Polly or Katrina Buckhout. He says she was "killed by a Yager rifleman belonging to a party under Kmerick who were patrolling on the west side of the Saw Mill River.
