Reclus was taken prisoner on 5 April into Fort Quélern. On 16 November he was sentenced to deportation for life. Because of intervention by supporters from England, the sentence was commuted in January 1872 to perpetual banishment from France. After a short visit to Italy, Reclus settled at Clarens, Switzerland, where he resumed his literary labours and produced Histoire d'une montagne, a companion to Histoire d'un ruisseau. There he wrote nearly the whole of his work, La Nouvelle Géographie universelle, la terre et les hommes, "an examination of every continent and country in terms of the effects that geographic features like rivers and mountains had on human populations—and vice versa." This compilation was profusely illustrated with maps, plans, and engravings. It was awarded the gold medal of the Paris Geographical Society in 1892. An English edition was published simultaneously, also in 19 volumes, the first four translated by E. G. Ravenstein, the rest by A. H. Keane. Reclus's writings were characterized by extreme accuracy and brilliant exposition, which gave them permanent literary and scientific value. According to Kirkpatrick Sale: In 1882, Reclus initiated the Anti-Marriage Movement. In accordance with these beliefs and the practice of union libre ("free unions"), which was common among working-class French in the mid-to-late 1800s, Reclus allowed his two daughters to "marry" their male partners without any civil or religious ceremonies, an action causing embarrassment to many of his well-wishers. Reclus had himself entered a free union in 1872, after the death of his first wife. In 1882 he also wrote Unions Libres, a pamphlet which detailed his anarchist and feminist objections to marriage. The French government initiated prosecution from the High Court of Lyon, arrested him and Peter Kropotkin as the International Association's organizers, and sentenced the latter to five years' imprisonment. Reclus escaped punishment as he remained in Switzerland. In a 1913 piece, Kropotkin, in admiration of Reclus, said that if anyone asked about the conflicts of the Middle East, that "I should merely open the volume of Elisée Reclus's Geographie Universelle L'Asie, Russe..." Reclus had strong views on naturism and the benefits of nudity. He argued that living naked was more hygienic than wearing clothes; he believed that it was healthier for skin to be fully exposed to light and air so that it could resume its "natural vitality and activity" and become more flexible and firm at the same time.
