In 1770 he was involved in an incident wherein a crew member was flogged after a failed mutiny. The crew member later died, and it was clear that his reputation had taken a big hit. So John Paul left Scotland and took command of a British vessel. Again, however, he put down a mutinous sailor, this time killing him with a sword in Tobago. Before he could be tried, however, he fled the area and essentially disappeared for 18 months.
In the meantime his brother, who lived in the Fredericksburg, Virginia, area, died. John Paul went to America to settle his brother’s affairs. It was at this time that he appended the last name “Jones” to his name. Shortly thereafter he joined the American Navy. During his time as an American naval officer, it doesn’t appear that he killed anyone, but in his later years, he sailed for the Russian Navy, where he was derailed by the accusation of rape of a ten-year-old Russian girl. It was only because of the murkiness of some of the details that gave the Empress Catherine some leeway to have him exiled rather than beheaded.
