He was assiduous in his attendance on Queen Hortense until the Hundred Days brought him into active service again.
Of the two other sons of Louis Bonaparte and Hortense, the elder, Napoleon Charles (1802-1807), died of croup at The Hague; the second, Napoleon Louis (1804-1831), died in the insurrection of the Romagna, leaving no children.
It is certain that, after the abdication and exile of Louis, Hortense lived in France with her two children, in close relation with the imperial court.
His brother Alexandre, vicomte de Beauharnais, married Josephine Tascher de la Pagerie (afterwards the wife of Napoleon Bonaparte) and had two children by her - Eugene de Beauharnais and Hortense, who married Louis Bonaparte, king of Holland, and became mother of Napoleon III.
In 1802 the First Consul married him to Hortense Beauharnais, a forced union which led to most deplorable results.
