an assassination attempt on Dumbadze revived the investigation into the case on July 20. As a result, Voykov was forced to leave Petersburg; in summer 1907 he was hiding in Kharkiv for several months, and then emigrated. Emigration In 1907 Voykov left Russia on the passport of his classmate. In March 1908 he arrived in Geneva, Switzerland. In September 1909 he entered the Physics and Mathematics Department of the University of Geneva. In Geneva he met Vladimir Lenin and, although he was not yet a Bolshevik, he remained a Menshevik-Internationalist during the First World War, actively spoke out against the "defencists", and was an active participant in the "1st Geneva Group of Assistance". In the spring of 1914 he married Adelaide Abramovna Belenkina, who studied medicine in Geneva. On April 24, 1915 their son Pavel was born. Following the February Revolution of 1917, he returned to Russia with his wife and son, though not in the same sealed carriage with Lenin, as it was often claimed, but together with Martov and Lunacharsky in the next group, which arrived in Russia on May 9, 1917. Activities in the Urals On returning to Russia, Voykov became a Commissar of the Ministry of Labor of the Provisional Government; he was responsible for resolving conflicts between workers and employers. After the July Days, when the Menshevik faction supported the repression against the rioters and Bolsheviks, Voykov left St. Petersburg for the Urals. There he soon joined the Bolshevik faction and was a member of Yekaterinburg Soviet and was engaged in trade union activities. After the October Revolution he joined the Yekaterinburg Military Revolutionary Committee. he was elected chairman of the Yekaterinburg City Duma. In January through December 1918 he was Commissar for Supply in the Ural Region Soviet. In this post, he directed transportation of precious metals from Yekaterinburg, successfully sought the supply of foodstuffs from the state reserves to the Urals and personally provided for its delivery. The Great War, two revolutions and the policy of nationalization of industrial plants led to the disintegration of normal economic ties. In order to supply the cities with food, the Soviets resorted to the brutal policy of prodrazvyorstka when armed prodotryads (food detachments) were sent to the villages. As a Commissar of Supply, Voykov also dealt with this. Soviet biographers also note that he managed to organize the exchange of Urals iron for Siberian grain and
