On 22 April 1936 Birraux was elected Superior General of the White Fathers. He succeeded Bishop
Paul Voillard. In his first years Birraux visited White Fathers locations in Europe and Canada, and in Algeria, Tunisia, Sahara, West Africa and the Gold Coast (now Ghana). He reorganized the White Fathers into provinces aligned with national borders. In 1939 the Tanganyikan missions of
Mbulu and
Turu were ceded to the
Pallottines. During
World War II Birraux was opposed to the armistice between France and Germany. Despite the difficulties, from his base in Algiers he maintained contact with members of the society in France, Italy, Belgium and the Netherlands, and also with missions in French Africa. Apart from Cameroon, Congo-Brazzaville, Gabon and Chad, all the French colonies in Africa remained loyal to
Marshall Pétain's right-wing and pro-Catholic Vichy regime rather than that of General
Charles de Gaulle in London.
General Weygand visited Birraux in Algiers in 1941 and gained assurance that he would support the Vichy regime. In 1943 the White Fathers assumed responsibility for the mission in
Oyo, Nigeria. In 1946 the society assumed responsibility for the mission in
Beira, Mozambique. Birraux suffered from
hypertension, and required treatment several times during the war years. He underwent surgery twice in 1945. He died from a
cerebral hemorrhage on 30 April 1947. He was succeeded as Superior General by Bishop
Louis-Marie-Joseph Durrieu. ==References==
