The treatment I receive as a Flag Officer is very different from what I expected. I am here under the sanction of a passport signed with His Excellency General Washington’s name. An expression in this Passport says, that I am to be considered as an Officer on parole. Judge by Yourself, Sir, how surprized I was to see myself, by the direction of Mr Breadforth a prisoner under the care of an American Officer, and confined to my lodgings not suffered to execute the business on which I was sent. Not satisfied with this my corporal is taken up, and put in the guard without my knowledge. Conscious that neither I, or my Corporal, has done any thing contrary to the commission I bear, therefore I take the freedom, Sir, to address You on the subject, and beg the favour to lay the matter before the Board of War; I am so well acquainted with the justice of this Board, that I not only flatter myself with an explanation of the indifferent treatment I have received, but with a speedy redress of the Grievances I have mentioned to You in this letter. I am to answer for my conduct as well, as to every thing, which happened to me to His Excellency General de Knyphausen. I have the honour to be, Sir, Your most obedient humble servant

The business, on which I am sent, is nearly executed, but before I leave this place, I must beg leave to execute His Excellency General de Knyphausen’s order, which is to recommend the protection of the Hessian Prisoners to the honourable Board of war, in particular the sick. I am wholly convinced, that as soon as the Board is informed of the disadvantage in keeping them in Goal, they will soon be removed, if not, an infection will take place, and the city may suffer. I am at the same time ordered to beg leave to go to Lancaster, to provide for the prisoners there, and return by the way of Reading to discharge the debts of the Hessian Officers left there when exchanged. But having met with Captain Heer in the Goal, I have agreed to go with him to Reading and deliver the necessaries for the prisoners in his hands, and he will send them to Lancaster, provided I can get a List of the prisoners names, their number, and different regiments they belong to, which Colonel Attlee has not been able to furnish me with in this city.

If I obtain the Board’s leave to go, I shall send an express to Lancaster, which will meet me at Reading. I have the honour to be The Board’s most obdt hble servant

We have been honoured with Your letter relative to the Hessian Prisoners. We very sincerely wish to have them accommodated in the best manner possible. Their sickness has been in a very great degree owing to their want of necessaries which depended upon Yourselves to supply, and we hope, as they are now supplied, their disorders will cease. It will be requisite that You provide the means of supplying them with medicines and Hospital Stores. They are certainly not crowded in the place of their confinement; but We are about taking measures to have most of the prisoners at this place removed. We should be happy to comply with Your wishes as to going to Reading and Lancaster, but we do not think it proper at this time. We have directed the Commissary General of Prisoners to take Order as to Your return, and he will assist in any measures for forwarding monies or supplies to the Prisoners at Lancaster or Reading. We have the honour to be very respectfully Your obedient servants

On the 22d of April five o’clock in the afternoon Quartermaster Hartzog and myself arrived at Philadelphia with the cloathing for the Prisoners entrusted to our care.

We alighted at the house of Mr Bradford Commissary of Prisoners, and acquainted him with our business. He desired to see our Pass, which after reading it, he locked up in his bureau. We asked him to return it, and he laughed at us, saying that we should have in due time; He then conducted us to our intended lodgings, where he delivered us to the care of an American Officer, without whose knowledge we were directed not to do any thing.

Surprizing as this treatment appeared to us, we acquiesced in it till next day, when we asked the Officer to go out with us. The Officer consented, but we had not sooner got into the street, then we were met by the above mentioned Bradford, who sent us back to our lodgings, and directed the Officer to consider us as prisoners not allowed to stir till further orders. We desired an explanation of this order, but it was not given. An hour after this my servant informed me of the non commissioned Officers, that came with us, being carried off by a guard and put under arrest. I complained to the Officer of it, but to no purpose. I therefore wrote to the Board of War, but nobody being allowed to come to us, the letter remained on the table for four and twenty hours, when the Officer was so good as to forward it.

Though I received no answer to that letter, it had, I conceive, the good effect to occasion a message to me from the Board of War by Colonel Nicola, who promised the Sergeants should be released, sent to our lodgings, and permission should be given to us to distribute our cloathing to the prisoners. This promise was performed, but we were treated like prisoners to the moment we left Philadelphia.
