My Lai Massacre on the newspaper front page

An infamous massacre perpetrated by US troops in Vietnam was kept a military secret for more than a year. The first public acknowledgment was a small report in The New York Times on September 7 1969, confirming that First Lieutenant William L. Calley had been charged with the murder of civilians in Vietnam. A report by Seymour Hersh appeared on the front page of St. Louis Post-Dispatch on November 13 and his more detailed account with horrific black and white photographs taken by Sergeant Ronald Haeberle was published shortly afterwards, on November 20, in The Plain Dealer.
