The Irish say the "Officer of High Rank in the 30th Division of French Infantry" was Louis-Antoine-François de Marchangy.
His bio supports his authorship of such a work, though fails to mention military service.
Thus, it goes to the original French edition of
Le siège de Dantzig en 1813 . Par M. de M********
Marchangy, Louis-Antoine-François de
Chaumerot jeune (Paris), 1814
