Napoleon's triumph at Marengo secured his political authority and boosted his popularity back home, but it did not lead to an immediate peace. Bonaparte's brother, Joseph, led the complex negotiations in Lunéville and reported that Austria, emboldened by British support, would not acknowledge the new territory that France had acquired. As negotiations became increasingly fractious, Bonaparte gave orders to his general Moreau to strike Austria once more. Moreau and the French swept through Bavaria and scored an overwhelming victory at Hohenlinden in December 1800. As a result, the Austrians capitulated and signed the Treaty of Lunéville in February 1801. The treaty reaffirmed and expanded earlier French gains at Campo Formio. Britain now remained the only nation that was still at war with France.

Where did the victory for Napoleon that secured his political power and increased his popularity in France occur?
