Henry W. Antheil Jr. |
Bullitt presented his credentials to the Soviet government on December 13, 1933; Antheil and other newly-minted foreign service employees arrived at the embassy several months later.
After serving five years, during which Antheil was responsible for maintaining cryptographic communications devices and their codes and ciphers in the Soviet Union and Northern Europe, he obtained a transfer to the U.S. Legation in Helsinki, Finland, a country for which he developed a particular appreciation during his travels.
When the Soviet Union concluded mutual assistance treaties with the Baltic States in 1939, and moved toward their occupation in 1940, Antheil was dispatched to close the U.S. Legation in Tallinn, Estonia, and retrieve sensitive documents. On June 14, 1940, he boarded the Finnish airplane Kaleva for the return flight to Helsinki, with several diplomatic pouches in hand, but the plane crashed over the Gulf of Finland ten minutes after takeoff from the Tallinn airport.
