The Berlin border between East and West Berlin is closed. The zonal boundary is sealed in the morning by East German troops. “Shock workers” from East Germany and Russia a seal off the border with barrier of barbed wire and light fencing that eventually became a complex series of wall, fortified fences, gun positions and watchtowers heavily guarded and patrolled. In the end, the Berlin Wall was 96 miles (155 km) long and the average height of the concrete wall was 11.8 ft (3.60 m). Over the course of the Wall’s existence, 133 people were confirmed killed trying to cross into West Berlin according to official sources, while a victims’ group puts the number at over 200 dead. There were also some 5,000 successful escapes into West Berlin. The August 13 operation lasted 24 hours.

Don’t hesitate to use your weapon even when border breaches happen with women and children, which traitors have often exploited in the past.”


Construction of the infamous ‘Stutzwandelement UL 12.11’, known also as Grenzmauer 75 (Border Wall ’75) begins. This new installation — a second wall — penetrated deeper into East German territory and included a touch-sensitive, self-firing fence. The product of a large-scale development and testing program, it was made of L-shaped sections of pre-cast concrete used by farmers to build open silos. Each section was 3.60 meters high and 1.20 meters wide and was topped off by a smooth asbestos-concrete pipe 40 centimeters in diameter. Consequently, the Wall becomes harder to penetrate. Yet this did not put an end to attempted escapes. As a result, East German authorities increase their control of the border structures.
