Concerned for her entire family's safety, Natalia made plans for the children to be taken abroad. With the help of the Danish embassy, which was next-door to Princess Puyatina's apartment, George was smuggled out of the country to Denmark by his nanny, Miss Neame. The Danes extended diplomatic protection to the villa in Gatchina by pretending to rent it and flying the Danish flag over the house. Natalia wanted to join Michael in Perm, and after repeated pleading received a travel permit to join him. They spent about a week together, until an army of disgruntled Czechs advanced on Perm. The Bolsheviks had attempted to ship prisoners-of-war from Austria-Hungary out of Russia, ethnic Czech troops amongst them. The Czechs, however, were not going home to fight once more for the Austrian empire, but to fight for a separate independent homeland. The Germans demanded that the Bolsheviks disarm the Czechs, with the result that the Czech forces joined with the White Army, fighting against the Bolsheviks. With the approach of the Czechs, Michael and Natalia feared that she would become trapped in Perm, possibly in a dangerous situation, and so on 18 May she left for Moscow.
