A young Navy doctor has put down his personal professional experiences in the refugee camps through which over 600,000 people made the ""passage to freedom"", from Communist held Northern Viet Nam en route to Saigon, following Dien Bien Phu and Indo-China partition. Dr. Dooley combines his description of the state of the refugees- so often the victims of terrible poetic injustice in the form of Communist atrocities (the teacher deprived of his tongue, the students of their ears)- with a description of the total situation. With the Haiphong area gradually reduced until by treaty arrangement it was to become Communist ground in May 1955, the medico and his staff found increasing difficulties. They managed to see off a statue of the Lady of Fatima and the wonderful Tonkinese mother of a thousand often- transported orphans to the comparative safety of Saigon. The doctor was impressed with the nobility of his charges and tells of brave flights to freedom, noting that most fled to practise their religion, Catholicism. His private public relations campaign for America took the line that this was American Aid sent through the American Navy; he won friends by learning Vietnamese and by service. He believes that America has in its military services a ready-made public relations force. While the expression of personal gratitude is frequent, it lends a folksy quality and does not intrude too much.
