As a "chef de brigade", he then served in the Egyptian expedition and won further distinction at Acre and Aboukir. Returning to Europe with Napoleon, Bessières was present at the Battle of Marengo (1800) as second-in-command of the Consular Guard. General Jean Lannes, commanding a corps at Marengo, felt that Bessières didn't support his faltering troops sufficiently, and a long running feud arose between them. At the close of the battle, Bessières led a successful cavalry charge with the Guard Cavalry, though its effect on the battle was not as decisive as Napoleon pretended. It was General François Étienne de Kellermann´s cavalry charge that won the battle for Marengo but Napoleon gave the credit largely to his own Guard Cavalry.
