He used Jamaica on and off as a refuge during the St Domingan slave's rebellion in the early 1790s and having served with the British Expeditionary Force in St Domingue, Peter and William went back to Jamaica when the British withdrew from St Domingue in October 1798 and settled in Kingston amongst other similar French colonial families. (We know that Peter and William were in St Domingue in July 1798 from a surviving notarised document of the transfer from Peter to William of some property in the parish of Jérémie.) Peter died in Kingston only a few months later, aged about 49 years, as a result of a riding accident.
