The assassination of Emperor Paul I on 23 March 1801 gave Anna an opportunity to carry out her plan to escape. By August of that year, her mother was informed that the grand duchess was seriously ill. Once informed about her daughter's health, Duchess Augusta came to visit her. In order to have a better treatment she took Anna to Coburg, with the consent of both the new Emperor Alexander I and Grand Duke Konstantin. Once she arrived to her homeland, Anna refused to come back. She never returned to Russia.
