If such an incident occurred, it would be reflected in George Washington's papers. No such mention is made. Rather, mention is made about carrying out the New York provincial congress' orders to have prominent Tories arrested.
From his May 21, 1776 letter to Philip J. Schuyler describing problems being created by the Tories:
Dear Sir: I have inclosed for your Perusal Copies of two Informations, and a Letter I received on Saturday last from the Committee of King's District by the Hands of a Martin Bebee, who says he is their Clerk and was sent Express.
From these you will readily discover the diabolical and insidious Arts and Schemes carrying on by the Tories and Friends to Government, to raise Distrust, Dissensions and Divisions among us.
Having the utmost Confidence in your Integrity, and the most incontestible Proof of your great Attachment to our common Country and its Interest, I could not but look upon the Charge against you with an Eye of Disbelief, and Sentiments of Detestation and Abhorrence, nor should I have troubled you with the Matter, had I not been informed that Copies were sent to different Committees and to Governor Trumbull, which I conceived would get abroad, and that you, (should you find that I had been furnished with them) would consider my suppressing them, as an Evidence of my Belief, or at best of my Doubts of the Charges.
The Confidence and Assurance I have of the Injustice and Infamy of the Charges against the Convention, obliged me also to lay the Matter before them; least my not doing it, should be construed a Distrust by them of their Zeal, and promote the Views of the Tories; who, to excite Disorder and Confusion, judge it essential, to involve those in high Departments in a Share of the Plot, which is not unlikely to be true in some Parts, believing that our internal Enemies have many Projects in Contemplation, to subvert our Liberties.
His May 21, 1776 statement before the New York Convention:
Gentn: Congress having been pleased to request my attendance at Philadelphia, to advise with them on the Situation of affairs and being about to set out immediately; I judged it proper to give Major Genl. Putnam Instructions similar to those I have the honor to inclose you; for the regulation of his Conduct, in case you come to any determination respecting the Tories here and on Long Island and should have occasion for Military assistance, to carry it into execution. I have &ca.
His May 21, 1776 instructions to General Putnam:
Sir: I have reason to believe that the Provencial Congress of this Colony have in Contemplation a Scheme for Siezing the principal Tories, and disaffected Person's [in the most obnoxious parts of the Government] on Long Island, in this City, and the Country round about; and that to carry the Scheme into Execution, they will be obliged to have recourse.
I need not recommend secrecy to you, as the success, you must be assured will depend absolutely upon precaution, and the dispatch with which the measure, when once adopted, is executed.
General Green will, tho' not in person perhaps, have a principal share in ordering the detachments from his Brigade on Long Island, of course will be a proper Person to let into the whole Plan. I wd. therefore when application is made by Congress, have you and him concert Measures with such Gentlemen as that body shall please to appoint and order the execution with as much secrecy and dispatch as possible and at the same time with the utmost decency and good order.
Finally, none of his other instructions or orders to General Putnam revealed content that would corroborate Kilt's opinion.
