After a brief informal meeting two months earlier when they were impressed with each other, Countess Marie Walewska formally meets Napoleon Bonaparte at a ball in Warsaw. When Napoleon notes that her husband is three times her age, and as he is taken with her charms, he unsuccessfully tries to seduce her. She ignores his frequent letters and flowers until a few grim Polish leaders led by Senator Malachowski urge her to give into his desires as a personal sacrifice in order to save Poland. She goes to him despite the humiliation of her husband, who leaves for Rome to annul their marriage. They are extremely happy for a while; Napoleon divorces childless Empress Josephine and Marie eventually becomes pregnant. She is about to tell Napoleon about her baby when he tells her he decided to marry Archduchess Marie Louise of Austria. He explains that it will be a political marriage to insure his future son could rule securely with Hapsburg blood in him. It will not affect their relationship, he says, but Marie Walewska leaves to have her baby alone without telling Napoleon she is expecting his child.
