When France entered the war, there were patriotic demonstrations in the streets of Paris, with crowds singing "La Marseillaise" and chanting "To Berlin! To Berlin!" But Napoleon was melancholic. He told General Lepic that he expected the war to be "long and difficult", and wondered, "Who knows if we'll come back?" He told Marshal Randon that he felt too old for a military campaign. Despite his declining health and the fact he was practically dying, Napoleon decided to go with the army to the front as commander in chief, as he had done during the successful Italian campaign. On 28 July, he departed Saint-Cloud by train for the front. He was accompanied by the 14-year-old Prince Imperial in the uniform of the army, by his military staff, and by a large contingent of chefs and servants in livery. He was pale and visibly in pain. The Empress remained in Paris as the Regent, as she had done on other occasions when the Emperor was out of the country.
