He fought in the Haitian Revolution as a sous lieutenant and later as a lieutenant . Empire . During the War of the Third Coalition the French Army of Italy under Marshal André Masséna faced Archduke Charles , Duke of Teschen ' s Austrian army . Lacour led a brigade in Julien Augustin Joseph Mermet ' s cavalry division consisting of four squadrons each of the 24th and 30th Dragoon Regiments . At the Battle of Caldiero on 29 – 31 October 1805 , Lacour ' s brigade was attached to Guillaume Philibert Duhesme ' s 4th Division . On the 30th , Duhesme ' s division deployed on the right with Lacour ' s dragoons guarding the army ' s extreme right flank . The plan allowed for Jean - Antoine Verdier ' s division to cross the Adige River and extend Duhesme ' s right . Masséna assigned Duhesme the task of capturing the town of Caldiero . In the event , Verdier ' s attack miscarried and Duhesme captured Caldiero without help . However , the day ended in stalemate after bitter fighting . Every unit was committed to the fray except Mermet ' s other brigade which was made up of cuirassiers . On the 31st , Verdier ' s relatively fresh division attacked but was stopped . Charles ordered his army to retreat the next day . On 11 November 1805 , the Austrians fought a successful rear guard action at Valvasone on the Tagliamento River in which the 23rd and 30th Dragoons were present . Lacour led four regiments of dragoons in action at Flitscher - Klause ( Bovec ) on 19 November . General - major Heinrich Bersina von Siegenthal commanded two artillery pieces and 1 , 200 Austrians in the " De Ligne " Infantry Regiment Nr . 30 . Because the action was fought in a mountain pass , the Austrians were able to hold off Lacour ' s column . Since no French officers became casualties , losses were probably light . The 23rd , 24th , 29th , and 30th Dragoon Regiments were the only units of that type with Masséna ' s army . Lacour ' s independent force eventually linked up with Michel Ney ' s VI Corps at Villach . Lacour participated in the Invasion of Naples in 1806 . In March 1806 , Mermet ' s cavalry division was organized with the 23rd and 24th Dragoons in the 1st Brigade and the 29th and 30th Dragoons in the 2nd Brigade , though no brigadiers were named .
