On January 24, 1962, twenty-eight Berliners succeed in escaping from East to West through a twenty-seven-meter-long tunnel that they built themselves. The spectacular escape under the Wall is followed by other similar attempts. In the first half of 1962, a total of sixty East Berliners succeed in smuggling themselves through six tunnels under the Wall. But these attempts claim human lives. In March 1962, a person assisting with an escape is shot dead. Three months later, a sergeant in the [East German] People’s Police is killed. The GDR border commandos now refine their surveillance and security tactics. There are eight more attempted escapes in the second half of 1962 but only one succeeds. Twenty would-be escapees are arrested. Once again, someone trying to assist with an escape attempt is killed. Nevertheless, GDR citizens continue trying to dig their way through to West Berlin.
