Aug. 23, 1961 - The Western powers deployed 1,000 troops of their West Berlin garrison, backed by 10 40-ton U.S. tanks, along the border with East Berlin today. This was the swift Allied answer to the attempt by East German Communists to establish remote control over a 110-yard zone all along the West Berlin side of the 25-mile border. The Communists have warned all persons to stay at least 110 yards away from both sides of the intracity border. Two of the American tanks were on Friedrichstrasse, one of them about 40 yards behind 10 soldiers with machine guns. The soldiers took up positions directly on the border line.
