After the successful Bolshevik coup of November 1917, the Petrograd newspapers published a decree summoning all male Romanovs to report to the dreaded Cheka, the secret police. Initially they were just required not to leave the city. In March 1918, the Romanovs who registered were summoned again, now to be sent away into internal Russian exile. Sergei Mikhailovich was sent to Viatka, a small town in the foothills of the Ural Mountains. With suitcases in hand, the grand duke arrived at the Nicholas railway station on the afternoon of 4 April 1918. Sergei’s personal secretary, Fedor Remez (1878–1918), followed him in his exile. At seven that evening, the train pulled out of Petrograd headed east to Siberia. Grand Duke Sergei departed to his destiny in the company of his secretary, three sons of Grand Duke Konstantine Kosntantinovich (Princes: Ivan, Konstantine and Igor Konstantinovich) and Prince Vladimir Paley, the son of the morganatic marriage of Grand Duke Paul Alexandrovich. In Viatka, the Grand Duke was lodged in a different house from his much younger relatives. Although they all were virtually prisoners, they were allowed to walk freely around town, and could attend services at a local church. However, their situation changed after only eleven days.
