Napoleon was at Châlons-sur-Marne with the army of Marshal Patrice de MacMahon. MacMahon, Marshal Bazaine, and the count of Palikao, with the Empress in Paris, all had different ideas of what the army should do next, and the Emperor had to act as a referee. The Emperor and MacMahon proposed moving their army closer to Paris to protect the city, but on 17 August Bazaine telegraphed to the Emperor: "I urge you to renounce this idea, which seems to abandon the Army at Metz... Couldn't you make a powerful diversion toward the Prussian corps, which are already exhausted by so many battles? The Empress shares my opinion." Napoleon III wrote back, "I yield to your opinion." The Emperor sent the Prince Imperial back to Paris for his safety, and went with the weary army in the direction of Metz. The Emperor, riding in an open carriage, was jeered, sworn at and insulted by demoralized soldiers.
