the viaduct of Dannemarie, and the front stabilised and extended from the Vosges to the Swiss frontier. The population suffered artillery bombardments and, for fear of spying, many were evacuated into those communes untouched by war. Sundgau reverted to France in 1918, but its reintegration posed several problems; since Alsace was German speaking, they now saw themselves obliged to express themselves in French. By way of derogation, German was taught in schools for three hours a week. The administration was only in French and the mayor was appointed by the French government. Between the wars, 56% of the population worked in agriculture, 28% in industry and only 7% in services. In the Second World War after the declaration of war, the communes bordering on the Rhine were evacuated. The German army crossed the river on 15 June 1940. Following the Armistice of 22 June, Sundgau was once again in German hands. Elsaßian Jews, a few North Africans and French-speakers were expelled to the free zone between it and Vichy France, while the school system was changed back again to a only German speaking system (like pre 1918). Communes were renamed (received their pre 1918 old German names back), and youngsters enrolled in Hitler Youth from 1942. From then also, men born between 1914 and 1925 were drafted in the Wehrmacht. General Jean de Lattre de Tassigny's troops reached the Sundgau in November 1944, with Seppois-le-Bas (Nieder Seppbach) being the first. As after the first World War, language issues arose. From 1945 to 1984 the use of German in newspapers was restricted to a maximum of 25% (despite the fact that the population was still mainly german speaking). Post-war, there was a period of reconstruction and economic growth. Jean Fourastié's Trente Glorieuses, the thirty years of economic growth 1945 to 1973, ended by the first Oil Crisis, and the number of agricultural workers dropped year by year. More than 35% of the population currently work in services. Organisation Sundgau is an arrondissement (the arrondissement of Altkirch) and is divided into 4 cantons: Dannemarie, Altkirch, Hirsingue and Ferrette. These run roughly along a North/South axis (see map) and consist of 112 communes. These communes are in turn grouped into 8 communities and one village (Bernwiller) for economic and tourism promotion purposes.
