Jacques de Menou, Baron of Boussay, succeded Kléber at the head of Egypt after the latter's assassination on 14 June 1800. Far less popular a military commander than his predecessor, de Menou converted to Islam and married a rich Muslim Egyptian woman with whom he had a son, Jacques Mourad Soliman, born in Rosetta. Upon his conversion, he took the name of 'Abdullah with which he signs the present letter.
His army was defeated at Alexandria on 21 March 1801 and he is known for having surrendered the Rosetta Stone to the British.
