Rutland 21st March 1780
My rude State of health, which Since I came to this place has been daily improving puts me under the necessity of troubling your Excellency wt. my present address.
Sometime before I had the misfortune of becoming a prisoner of war, I made application to the Princ of Hesse for leave to return to Germany: His Royal Highness (in consideration of my long service for forty two years & the want of health, which renders me incapable of active Service) will I have no doubt grant my request, & orders for that purpose, I am convinced have long ago now been sent to New york.
From the above motives, I presume to Solicit Your Excellency for leave to go to New york on parole, and remain ther, till such time as an Exchange for me takes place, or a Genl on is settled.
Lt Stroderroth and Ensn Poli both officers belonging to the same Regt wt. me, were taken prisoners wt. me last april, the former is my nephew, a young man, who has been always under my protection, & I wish if possible to bring along wt. me to Germany; Should Your Excellency think proper to attend to my requisition, including these two Gentlemen in the parole, will add greatly to the obligation.
I take the liberty of inclosing a letter for Genl Knyphausen, which I request Your Excellency, will order to be forwarded—I hope Your Excellency, will pardon me for the trouble I give, & impart it to my situation. I have the Honor to be Sir Your very obedt humble Servant
J. C. Koehler
Colonel of the Hessian Troops
