In February 1913, Stalin was arrested while back in Saint Petersburg. He was sentenced to four years exile in Turukhansk, a remote part of Siberia from which escape was particularly difficult. In August, he arrived in the village of Monastyrskoe, although after four weeks was relocated to the hamlet of Kostino. In March 1914, concerned over a potential escape attempt, the authorities moved Stalin to the hamlet of Kureika on the edge of the Arctic Circle. In the hamlet, Stalin had a relationship with Lidia Pereprygia, who was thirteen at the time and thus a year under the legal age of consent in Tsarist Russia. In or about December 1914, Pereprygia gave birth to Stalin's child, although the infant soon died. She gave birth to another of his children, Alexander, circa April 1917.
