Five years later, after the outbreak of the War of the Third Coalition, Arrighi was named "aide-de-camp" to Marshal of the Empire Louis Alexandre Berthier and received a wound at the battle of Wertingen but was nonetheless present at the battle of Austerlitz two months later. In 1806 he was named "Major-colonel" of the Guard dragoons and fought in the War of the Fourth Coalition throughout 1806 and 1807 and was promoted to brigadier general on the field at the Battle of Friedland. The next year, in 1808, Arrighi was made "duc de Padoue" (duke of Padua) and was sent to Spain with the cavalry of the Guard. Returning to France, he served in the newly assembled Grand Army of Germany and fought the Austrians at the bloody battles of Aspern-Essling and Wagram. In 1810 he became a general inspector of cavalry and two years later he was given the command of all French troops on the North Sea coastline, from the Somme to the Elbe. Commanding the III Cavalry Corps, he fought in a number of battles between the Elbe and the Rhine and was governor of Leipzig during the epic Battle of Nations. During the 1814 Campaign in France, Arrighi was given command of an infantry division and covered Marshal Auguste de Marmont's retreat at the Battle of La Fère Champenoise and then took part in the Battle of Paris.
