I have been researching two brothers from Columbia Co. [then Albany Co. and in an area claimed by Massachusetts] during the Revolutionary War and used the New York Historical Manuscripts: Revolutionary Papers and NEW YORK IN THE REVOLUTION AS COLONY AND STATE. The latter lists Robert and Edward B. Coventry as British Prisoners of War. In the first source, the documents are an account of a court martial on or around 13 June 1777, the result of which is Robert is condemned to death. On the 18th of June he gets a full pardon. But then on 14 July 1777 he writes a petition saying he has been held for 8 weeks without a hearing and wants to be released. Edward's petition says the same thing. Can someone make sense of this?
