A special situation was the one of Vietnam in the context of catholic clandestine hierarchy. After Hồ Chí Minh proclaimed the Democratic Republic of Vietnam in 1945, France restored in the same year its colonial administration in the southern part of the country. In 1954, France lost the war, and Vietnam was divided alongs the 17th degree into a communist north and a western orientated southern part. In 1964/1965 the next war erupted, and the government of the north conquered step by step the south; the southern state surrendered on May 1, 1975, and Vietnam was reunified from Hà Nội as capital.
The position of the catholic Church became difficult because of the Church's strong French influence there. When the hierarchy was established on November 24, 1960, beyond the 19 reigning bishops were already 17 autochthon prelates and only two French ones; Paul Léon Seitz, bishop of Kontum in South Vietnam, left his office on October 2, 1975, as last missionary prelate.
In spite of the fact most dioceses also in the north were filled with bishops, the Holy See worried about the situation at the transition era at the war's end and appointed numerous new bishops. As soon as 1974 the southern Metropolitan provinces of Huê and Sái Gòn got three bishops, who were consecrated by Agnelo Cardinal Rossi on August 11, 1974:
01.07.1974 Phaolô Huỳnh Ðông Các, Bishop of Quy Nhơn
01.07.1974 Nicôla Huỳnh Văn Nghi, Auxiliary Bishop of Sài Gòn
01.07.1974 Ða Minh Nguyễn Văn Lãng, Bishop of Xuân Lộc
At the beginning of 1975 Rome separated the newly erected diocese of Phan Thiết from Nha Trang diocese within the Sài Gòn Metropolitan province and appointed a new bishop for the vacant see of Ðà Lạt:
30.01.1975 Bartôlômêô Nguyễn Sơn Lâm, P. S. S., Bishop of Ðà Lạt
30.01.1975 Phaolô Nguyễn Văn Hòa, Bishop of Phan Thiết
These both consecrations were the last regular ones in South Vietnam for quite a while. During progressing crisis several reigning bishops got the right to choose a coadjutor and to consecrate him immediately to assure a working diocesan government even in the case of impedition of the ordinary due to militaryr or political circumstances.

On April 24, 1975, Phaolô Nguyễn Văn Hòa was sent as Bishop to Nha Trang within Huê Metropolitan province, and Phanxicô Xaviê Nguyễn Văn Thuận, up to the Bishop of Nha Trang, became Coadjutor of Sài Gòn. Eight from ten new bishops were destinated for the Southern provinces. The Coadjutor of Huê was forbidden to fulfill his duties for long years, and the Coadjutor of Sài Gòn was kept into custody steadily, while the remaing prelates were able to administer their offices in the limits of those times. In 1994, Phanxicô Xaviê Nguyễn Văn Thuận was retired by St. John Paul II and became President of the Pontifical Council for Justice and Peace in 1998. In 2001, he was honoured with the cardinalate before he died the following year after long illness in the rumour of saintity. His beatification is in progress.
In 1976, St. Paul VI raised a bishop out of the northern part of the country, the Archbishop of the capital Hà Nội, Giuse Maria Trịnh Như Khuê, to Vietnam's first Cardinal. The announcement of this creation still was "in pectore" regarding to the question whether the new cardinal was allowed to leave Vietnam to Rome, but indeed Mons. Trịnh Như Khuê got his insignia in public. During the same year the last collective appointments took place:
Appointment and Consecration

09.12.1976 Giuse Nguyễn Thiện Khuyến, Coadjutor of Phát Diệm (Hà Nội) consecrated on 24.04.
While the two appointments for the Southern sees occurred clandestine, borth Northern bishops were nominated in the regular way. In 1982, the Coadjutor of Phú Cường resigned; he died in French exile.
Ða Minh Ðinh Huy Quảng
Ða Minh Ðinh Huy Quảng, appointed Auxiliary Bishop of Bắc Ninh in 1975, was the only prelate from the war's last phase who never was published; he died in 1992. Already on February 13, 1964, Giuse Lê Quỳ Thanh became Vietnam's first clandestine bishop as coadjutor of Phát Diêm, a very catholic and thus strongly by communist administration controlled diocese in Hà Nôi Metropolitan province. He died in 1974 and was never published.
