The political crisis between Prussia and France that began in May 1870 required his return from Cannes to Paris, where he participated in the emergency meetings of the Senate. His health worsened, and he only rarely could leave his house. The Empress sent him fruit from the imperial gardens, and on 24 June he was visited by his old lover, Valentine Delessert, and by Viollet-le-Duc. His health continued to decline; he told a friend: "It's well over. I see myself arriving at death, and am preparing myself".
