 On the 13th of August 1961, a wall of East German police stands at the Brandenburg Gate. All communication between the Eastern sector and those of the West has been cut as though by a knife. Before it, West Berliners stand stunned. Soon they give voice to the indignation. All objections, all approaches, they only answer, jets of water from Eastern armored trucks. Soviet attacks on the rights of the Western powers in Berlin showed that the war was meant to be a step towards control of the whole city, towards forcing out the Western powers. As the last escape routes were cut one after the other, final strambles so as not to be left behind in the prison. And this was an exodus not confined merely to the civilians. Even among the East German police guarding and maintaining the new barrier, there were some who decided that they too had reached the end of their term.
