One day, while they are hunting, they meet Andrei, who is enchanted by Natasha. Later, Andrei dances with Natasha when she attends her first ball and realizes that he wants to marry her. Prince Bolkonsky urges Andrei to wait a year, as Natasha is so young and the Rostovs are not their social equals, but promises to consent if Andrei still wishes to marry her then. With Natasha’s promise to wait for him, Andrei then joins the mission to Prussia, where Czar Alexander and Napoleon sign a peace treaty in June 1807. While Andrei is gone, however, Natasha is seduced by Anatole Kuragin, Helene’s brother, who is as cold-hearted and debauched as his sister. Even though he is secretly married, Anatole persuades Natasha to elope with him, but their plans are foiled by Natasha’s cousin Sonya and Pierre, who threatens Anatole with exposure of his marriage if he ruins Natasha’s reputation. Pierre’s threats come too late, however, and soon all of Moscow is gossiping about Natasha, who falls ill after Andrei ends their relationship. After several months, she begs Pierre to convey her regret to Andrei, and Pierre, who is in love with her, assures her that she is blameless, and that if he were free, he would ask for her hand.
