Being found guilty of treason, his entire estate was confiscated and he was imprisoned under guard, effectively a prisoner of war. His sons vehemently rejected the committee's offer of neutrality and continued in royal service, with one joining Simcoe's Rangers, and John Goodrich himself returned to privateering after escaping prison. Later in the war, Goodrich's privateering operation moved to New York, and grew over the course of the war to four fighting vessels; the largest, "The Dunmore", was a sixteen-gun ship. After the war, Goodrich and several of his family members left the United States and settled in England. He died in November of 1785, aged 63 years, and was interred at Topsham Church in Devon. Edmund Randolph, in his "History of Virginia", remarked regarding Goodrich and his sons that "Virginia never repaired the loss which she sustained in these men." In England, the descendants of John Goodrich were known as the Goodriches of Energlyn. His son John Goodrich, Jr. was High Sheriff of Glamorganshire in 1798, while another descendant, James Pitt Goodrich, was High Sheriff of Denbighshire in 1878. His Shedden descendants prospered as well; they lived for several generations at their estate at Spring Hill, East Cowes.
