While with the solicitor he had made the acquaintance of Alexandre Goujon, and they soon became close friends - he married Goujon's sister, Sophie (on 5 March 1793), and when his brother-in-law was elected deputy to the National Convention and sent as a representative-on-mission to the Revolutionary Armies of the Moselle and Rhine, Tissot went with him as his secretary.
