From 30 April-1 May 1945, the Waffen-SS Senior Group Leader (Obergruppenführer) and General of Police Karl Hermann Frank announced over the radio in Prague that he would drown any uprising in a "sea of blood". As rumors of an impending Allied approach reached Prague, the people of Prague streamed into the streets to welcome the victors. Frank ordered the streets to be cleared and instructed the German army and police forces in Prague to fire at anyone who disobeyed.
