“Acquainted with the conduct of Doctor Preserved Clap”
On 20 February, board members Richard Peters of Pennsylvania and Ezekiel Cornell of Rhode Island met and formulated a response to that petition:
The Board having considered the reference with which they were honored on the memorial of Preserved Clap, beg leave to observe, That it appears from his memorial and General [Henry] Knox’s letter that he hath been with the Army as a volunteer for eighteen months without pay or any emolument.The Congress approved that response the next day. Clap’s petition, which might include the letters from Knox and Lincoln, is preserved in the Congress’s files but not published.
That it farther appears by General [Benjamin] Lincolns and Knox’s letters that Mr Clap was sole inventor of stocking the Cannon that were supposed to be rendered useless by the enemy at Boston, and in the vicinity, in the spring of 1776; from which the Continent at large received a real benefit; for which he received no emolument but barely day wages.
From the foregoing state of facts it may be proper for Congress to resolve,
Resolved, That the supreme executive of the State of Massachusetts examine into the merit and services of Preserved Clap, and order payment on the account of the United States, for such sum as they think he may justly deserve; provided it shall not exceed one thousand dollars in bills of the new emissions:
That Preserved Clap be informed, that Congress cannot employ him in public service, consistent with their arrangements.
There is, however, a second published letter from Henry Knox on the doctor. On 13 March, Gen. John Sullivan wrote to Knox about him, and on 22 March the artillery commander replied:
I received your favor of the 13th instant, requesting a certificate from me, & such of my officers who were best acquainted with the conduct of Doctor Preserved Clap, & how he employed himself in the Army.This looks like the second time Dr. Clap threw himself into devising equipment for the army without arranging an official rank or contract, and without discussing pay. Not the wisest way to operate, especially when good money was scarce.
The result of my knowledge & information is that the said Preserved has great mechanical abilities, & that he joined himself to the Army in ’79, as a volunteer, ready to do any kind of work in his power, either for officers or soldiers, sometimes with & sometimes without pay.
When the Continental troops were principally withdrawn from West Point last August, the Doctor attached himself to the Post, but he declined to the best of my remembrance to be enrolled as an artificer, & apply himself to public work entirely.
Sometime in November he applied to me for a letter to Mr. Hodgson [Samuel Hodgdon, shown above], D[eputy].C[ommissary].G[eneral].M[ilitary]. Stores, the intent of which he informed was to procure assistance or permission to work with the artificers’ tools at Philadelphia to execute some design of a machine to destroy shipping, which he intended to present to Congress or the Board of War.
But I had not the least idea of his intending to claim pay for the time he had been with the army.
The Congress referred Clap’s case to Massachusetts, where the “supreme executive” was now Gov. John Hancock. The state archives might therefore contain more sources on Dr. Clap. However, I’ve found no evidence of pay for him on either state or national level.
TOMORROW: Last traces.
