He was appointed in 1858 to a command at home, and at the close of 1859 was selected to lead the French troops in the Anglo-French expedition to China. His conduct of the operations did not escape criticism, but in 1862 he received from Napoleon III, the title of comte de Palikao (from the Battle of Palikao); he had already been made a senator. The allegation that he had acquired a vast fortune by the plunder of the Old Summer Palace in Peking seems to have been without foundation.
