He would later run the 6th network of Trepper's seven espionage networks in France, providing intelligence from US and Belgian diplomats.

In 1938, Springer moved to Belgium and became an active member of the espionage network run by Anatoly Gurevich. Springer fought against fascist forces in Spain from 1937-1938. Springer ran the 6th network of Trepper's 7 networks in Europe, supplying intelligence garnered from US and Belgian diplomats.

After the raid at 101 Rue des Atrébates by the Funkabwehr on 12 December 1941, Mikhail Makarov was arrested, Springer fled to Paris with Gurevich on 15 December 1941. Springer was sent to Lyon by Trepper where he attempted to establish a new espionage network. However, Springer failed to establish a wireless telegraphy link with Moscow.
