At the end of the interview the two brothers parted with emotion. Lucien flung himself into his brother's arms, saying that doubtless he was embracing him for the last time, and left for Rome with his head high. He was obliged to yield only on one point, by sending to Paris his oldest daughter, Charlotte Marie, the issue of his first marriage with Christine Boyer. (She was born at Saint Maximini in February, 1795, and in 1815 married Prince Marius Gabrielli.) But the young girl had all her father's independent spirit. In Paris she was entrusted to the care of her grandmother, Madame Letitia, and she spoke so severely about the Imperial family in her letters, which were opened, that she was sent back to her father in Rome almost as soon as she had arrived in France. As for the idea of an annulment of the marriage or a divorce, Lucien absolutely rejected it. He preferred his wife to all the wealth, all the honors, all the kingdoms of the world. Jerome had yielded. Lucien did not yield. Napoleon left Mantua after his interview with his brother, and returned to Milan, where, December 17, he witnessed some naval sports in the arena of the circus, which was turned into a lake. There too, December 20, in the grand, hall of the palace, he adopted Prince Eugene as his son and declared him his heir to the crown of Italy. At the same time he issued these two decrees: "Wishing to give especial proof of our satisfaction with our good city of Venice, we have conferred, and by these letters- patent here present do confer, upon our dearly loved son, Prince Eugene Napoleon, our heir presumptive to the crown of Italy, the title of Prince of Venice." "Wishing to give especial proof of our satisfaction with our good city of Bologna, we have conferred, and by these letters-patent here present do confer, the title of Princess of Bologna upon our dearly loved granddaughter, the Princess Josephine." Napoleon left Milan, December 24, to return to Paris by way of Turin.
