In late 1977, due to unusual storms, numerous corpses washed up on beaches south of Buenos Aires, producing evidence of some of the government's victims. There were also hundreds of cases of babies and children being taken from mothers in prison who had been kidnapped and later disappeared; the children were handed over in illegal adoptions to families and associates of the regime. The CIA also reported that Operation Condor countries took very well to the idea of working together, and developed their own communications network and combined training initiatives in areas such as psychological warfare.
