According to your Excellency’s Desire I have the Honor to Send you a Summary Account of my Services in America.

I first joined the Army under your Excellency’s Command on the 6th of Octr 1777 with the Rank of Lt Col. of Engineers. I attended a Short time after the Marquis de la fayette when he attaked the british Post at Glocester & when after this I was determined by a Council of War to abandon & [blow] up fort Redbank, I, with Col. Du Plessis and a Sergeant of Artillery undertook & compleated the Busyness.

On the 17th of Novr I was promoted to the Rank of full Colonel. In the beginning of Decr was detached to Willmington with Genal Smallwood’s Division, where, being the only Engineer I erected Several Works for the Security of the garrison. In April 1778 I repaired at Valley-forge and followed your Excellency to Monmouth; then to the White plains, where I, with Col. La Radiere and Col. Villefranche reconnoitred all the Ground between the Camp and King’s Bridge, with Several Detachements under the Command of Generals Scott and Michlemberg.

In Septr following I was Sent, by your Excellency, to Philadelphia with Col. Villefranche to take a Survey of the River Delaware, in order to form a Plan of Deffence. Having been ordered in february 1779 to the Southern, this Busyness was compleated by Col. Villefranche.

I Staid in Sth Carolina, as Commanding Officer of the Engineers, under the Command of Genal Lincoln, till the taking of Charlestown. I was at the attack of the River of Stone-ferry and at the Sieges of Savannah & Charlestown, whose attack and Dffence I had the Direction of as Chief Engineer, and all of which I had the Honor of giving [plans] and journals to your Excellency last fall.

Having had the Misfortune to be taken prisoner at this last Siege, I could not be exchanged till the Month of August 1782, when I repaired immediately to New-Windsor.

Conscious that in all these Services my only Aim was to promote, as far as laid in my Power the Good of the Cause I had espoused, and that I Spared none of my faculties for it, I wish that your Excellency may be Satisfyed with the Same, and beg that you would give me a Certificate, for which I will for ever have the greatest Gratitude. I have the Honor to be with the greatest Respect Your Excellency’s Most obedient and most humble Servant
