The massacre at My Lai on March 16, 1968 continues to haunt students of the Vietnam War as a moment that challenges notions of American virtue. James Olson and Randy Roberts have combed unpublished testimony and have gathered a collection of eyewitness accounts from those who were at My Lai and reports from those who investigated the incident and its cover up. This new edition of My Lai includes an examination of the massacre's long-term impact on American public opinion and foreign policy. With five new sources, including documents from the fiftieth anniversary of the massacre, the second edition of the text provides eyewitness testimony of participants, thus helping students to evaluate the behavior of those involved in My Lai and its cover-up from a wider range of perspectives. Updated questions for consideration, chronology, and bibliography supplement the firsthand accounts. Available in print and e-book formats.
