After the start of the Franco-Prussian War in July 1870, Cézanne and his mistress, Marie-Hortense Fiquet, left Paris for L'Estaque, near Marseille, where he changed themes to predominantly landscapes. He was declared a draft dodger in January 1871, but the war ended the next month, in February, and the couple moved back to Paris, in the summer of 1871. After the birth of their son Paul in January 1872, in Paris, they moved to Auvers in Val-d'Oise near Paris. Cézanne's mother was kept a party to family events, but his father was not informed of Hortense for fear of risking his wrath. The artist received from his father a monthly allowance of 100 francs.
