Thiers, Adolphe (1839). Histoire de la Révolution française (in French). Vol. 10 (13th ed.). Paris, France: Furne et Cie. p. 299. From p. 299: "Mais son regret fut tel, que malgré sa destinée inouïe, on lui a entendu répéter souvent, en parlant de Sidney-Smith: Cet homme m'a fait manquer ma fortune." (But his [i.e., Napoleon's] regret was such that despite his extraordinary destiny, one heard him often repeat, in speaking of Sidney-Smith: That man made me miss my chance.)
