The freedom bell in West Berlin tolls in sympathy for East Germans on the first anniversary of the wall of shame that holds them prisoners. It was just a year ago that authorities in communist Germany, appalled at the numbers who were fleeing to the West, threw up the wall. German boss, Olbricht, cut worshipers from their churches, separated parents from their children, but at the same time, he unwittingly united Germany as never before. On this anniversary, wreaths are placed where people died, jumping to freedom, and at checkpoints authorities are on the alert to prevent outbreaks among West Berliners who might seize on the anniversary to vent their wrath on East German guards. U.S. patrols check a segment of the 95-mile-long barrier. There are brief memorial services led by Mayor Willy Brandt in tribute to the scores who died seeking freedom. The slogan of the day among the West Berliners is marked on the cross, We Accuse. They march along the wall, a display of silent contempt for communist efforts to imprison their friends and relatives. At dusk, tensions erupt in a rock-throwing barrage. The police have their hands full and don't succeed in quieting the Westerners for some time. It's the anniversary day of the shameful war.
