During World War II, Czapska lived in Poland, and was a member of the Żegota during this time; this led to her crossing the green border and moving to France in 1945, where she lived the rest of her life. For a short time, Czapska helped with the startup of Tygodnik Powszechny, and after moving to France she worked on Kultura, a Polish exile magazine. She was also a member of Polish Society of Arts and Sciences Abroad. During her time in exile, her works were subject to censorship, which was discovered after Tomasz Strzyżewski defected to Sweden, publishing the information which noted her name among many others. Later in life, she focused on literary works, namely "Dwugłos wspomnień", "Europa w rodzinie", and "Czas odmieniony". In 2014 two of her books, "A Family of Central Europe" and "Through the Storm" were published in one book for the first time in English.
