She then relocated to Russia and volunteered in the surgical department of Petrograd"s largest hospital for several months before being employed by a hospital unit financed by the National Union of Women"s Suffrage Societies. From there, she travelled with the Russian Red Cross to the Caucasus, where she performed surgical duties, and directed a hospital in Erzurum for a time before returning to Russia.
