"At midnight on August 13, all troops involved in the construction of the Wall are alerted. The action begins, it is supported in the hinterland by the Soviet armed forces stationed in the GDR. At 0.30 o'clock, tanks roll over the street Unter den Linden. Shortly after 1 o'clock the lights go out at the Brandenburg Gate. Armed GDR border police and members of the combat groups are positioning themselves at the demarcation border. Ghostly scenes take place: pavement is torn open in the spotlight of the military vehicles. Piles are rammed into the ground, barbed wire rolled out, tank barriers erected. The "Melodies for the Night" are running on Berliner Rundfunk. At 1:11, they are interrupted. The news anchor reads out a special message: "The Governments of the Warsaw Pact States are addressing the People's Chamber and the government of the GDR with the proposal to introduce such an order on the West Berlin border, which reliably shunts the activity of rioting against the countries of the socialist camp and around the whole area of West Berlin a reliable watch is ensured. " This informs the citizens of the GDR about what has already been going on for 71 minutes: the building of the Wall."
