Following the occupation of France in 1940, Sautot declared the New Hebrides' allegiance to the Free French on 20 July, the first territory to do so.[1] On 13 September Charles de Gaulle appointed him Governor of New Caledonia.[1] He sailed to New Caledonia and, greeted by large crowds on his arrival, went straight to Government House and removed Colonel Denis from office.[1] He subsequently set up the Bataillon du Pacifique [fr] which sailed in May 1941 to fight in North Africa and Europe.[1] He was made a companion of the Order of Liberation on 1 August 1941, later also becoming a Commander of the Legion of Honour and an Officer of the British Empire.[2] However, after the new French High Commissioner in the Pacific Georges Thierry d'Argenlieu arrived in 1942, disagreements between the two led to Sautot being deported to Auckland in New Zealand in May 1942.[1]
Later in 1942 Sautot was appointed Governor of Ubangi-Shari by de Gaulle, a post he held until retiring in 1946.[1] He then returned to New Caledonia with his New Caledonian wife.[1] He entered local politics, and served as mayor of Nouméa between 1947 and 1953.[2]
Sautot died in a clinic in Nouméa in March 1963.[1]
