In 1780, the General Gates went missing. No British warship laid claim to sinking her.
But the Navy happens to have some records:
General Gates returned to Boston harbor 13 April 1779, so unseaworthy from battering gales that her crew, at times, had despaired of ever reaching port. She was ordered sold 2 June 1779. In August she was loaned by the Navy Board to the Deputy Commissary of Prisoners at Boston to convey prisoners to New York. On completion of this mission, she was sold.
One wonders how unseaworthy the General Gates was when she sailed for her final, fatal voyage.
