On June 14 while the world's attention was focused on the fall of Paris to Nazi Germany a day earlier, the Soviet military blockade on Estonia went into effect. Two Soviet bombers downed a Finnish passenger airplane "Kaleva" flying from Tallinn to Helsinki carrying three diplomatic pouches from the U.S. legations in Tallinn, Riga and Helsinki and over 120 kilograms of diplomatic mail by two French embassy couriers. The US Foreign Service employee Henry W. Antheil Jr., the French couriers and other passengers were killed in the crash.
