After the Armistice, Princess Caradja went back to Bucharest, and devoted herself to social work, most notably, at Saint Catherine's Crib, a complex of orphanages started by her mother, which housed more than 3,000 children. In 1920, she gave birth to a third daughter, Alexandra (1920-1997). The second daughter died in Vienna in 1933, while her eldest daughter and her husband (Constantin Emandi) were killed in the deadly earthquake of 10 November 1940. World War II and aftermath The princess first became known internationally as a result of her opposition to Romania's alliance with Nazi Germany during the Second World War (see Romania during World War II). When the oilfields at Ploieşti were bombed by the Allies in August 1943 in Operation Tidal Wave, she personally took custody of surviving Allied crews, saw that they were cared for in her hospitals, and facilitated their escape to Italy. During the Allied bombings of spring and summer 1944, several American airmen landed on her estate at Nedelea, after either emergency landing or parachuting. Throughout the war, she eased the burden of captivity for more than one thousand flyers who had been shot down. Those deeds earned her the nickname "Angel of Ploieşti" among the airmen. One of the pilots who survived crash landing, and escaped thanks to her efforts, was Richard W. Britt, who recounted the story in a book, many years later. After the Communist regime was established in Romania, her orphanages and foundation were nationalized in 1949. Her daughter, who had left for Paris in 1948, helped the princess escape in early 1952, with assistance from the French secret services; she left the country on a Danube tanker, arriving after 8 weeks in Vienna. During the winter of 1954–55, the princess directed relief efforts for children in Algiers, in the wake of the September 9, 1954 earthquake. She traveled widely, giving talks in France on "Life Behind the Iron Curtain", and speaking at the BBC. In America In December 1955, Caradja received a visa to come to the United States; soon after landing, she appeared on the Dave Garroway show. She resided in the U.S. for more than 35 years, mainly in the town of Comfort (in the Hill Country of Texas), but also in Baltimore, Maryland and in Kansas City. While traveling across America, speaking at various venues, she found more than five hundred of the former prisoners of
