she was recalled with Rudolf to Moscow in August 1935. Poland In September 1935 they were both posted to Poland where, apart from at least one more lengthy visit to Moscow, they would remain till Autumn 1938. The couple lived mostly in the Polish capital Warsaw during this time and carried out espionage to assist underground Polish communists, apart from a three-month mission in the Free City of Danzig in 1936. In the meantime it would later transpire that in 1937 the Soviets awarded her the Order of the Red Banner for her espionage work in China. Without ever wearing a uniform, she now held the rank of colonel in the Soviet military.
