Hitler, looking very feline, as he plays cat-and-mouse with President Hácha.
On the evening of 14 March 1939, Hitler summoned President Hácha to the Reich Chancellery in Berlin, then deliberately kept him waiting for hours. Finally, at 1:30 a.m., on 15 March 1939, Hitler saw the President. He told Hácha that as they were speaking, the German army was about to invade Czechoslovakia. All of Czechoslovakia's defences were now under German control following the Munich Agreement in September of the previous year. The country was virtually surrounded by Germany on three fronts.
Hitler now gave the President two options: cooperate with Germany, in which case the "entry of German troops would take place in a tolerable manner" and "permit Czechoslovakia a generous life of her own, autonomy and a degree of national freedom" or face a scenario in which "resistance would be broken by force of arms, using all means." After Hermann Göring threatened to subject Prague to merciless aerial bombing, the 66-year-old Hácha suffered a heart attack and had to be revived by an injection. Hácha contacted his government at 4 a.m. and "signed Czechoslovakia away" to Germany.
At 5:00 a.m. on March 15, 1939, Hitler declared that the unrest in Czecho-Slovakia was a threat to German security. On the morning of 15 March, German troops entered Bohemia and Moravia, meeting no resistance. Carpatho-Ukraine immediately declared its independence as the Republic of Carpatho-Ukraine, which lasted for only one day. With Hitler's agreement, Hungarian troops occupied and annexed the short-lived country the next day. On 16 March, Hitler entered Czechoslovakia and from Prague Castle proclaimed the new Protectorate of Bohemia and Moravia. Hitler re-installed Tiso as President of Slovakia, telling the world that Slovakia was now independent but under the protection of Germany. In reality, Slovakia was now a mere puppet state, though still with more freedom than Bohemia and Moravia.
