Video: '1939 Invasion of Prague'

(Wednesday, March 15, 1939, 6:00 a.m. Central European Time) — The German Army poured into Bohemia and Moravia this morning as they began a complete occupation of Czechoslovakia in direct violation of the Munich Agreement signed Sept. 30, 1938.

The Germans met no resistance and by evening, Adolf Hitler was able to make the triumphant entry into Prague.

Hitler had summoned President Emil Hácha to Berlin and during the early hours Mar. 15, 1939, informed Hácha of the imminent German invasion.

Threatening a Luftwaffe attack on Prague, Hitler persuaded Hácha to order the capitulation of the Czechoslovak army.

Hácha suffered a heart attack during the meeting, and had to be kept awake by medical staff, eventually giving in and accepting Hitler’s surrender terms.

It was the first non-Germanic territory to be taken by the Nazis.
