It was fortunate for Napoleon that he married Josephine before he was made commander-in-chief of the armies of Italy.

Her fascinating manners and her wonderful powers of persuasion were more influential than the loyalty of any dozen men in France in attaching to him the adherents who would promote his interests.

Josephine was to the drawing-room and the salon what Napoleon was to the field--a preeminent leader.
